View Full Version : Street Grip review

I've NOT seen anyone's comments yet on the RideTech Street Grip that was released. I removed Hotchkis 3" lowering leafs and 500# rate front coils today and installed Street Grip front/rear. I previously enjoyed the "track cornering feel", but the car BEAT me up going through town, and was too stiff for my liking at highway speeds. I did NOT enjoy driving my car. Enter Street Grip.

PERFECT, exactly what I was working for. After a short 5 mile test drive, I believe I will like it. The first part of a sharp bump is softened, but quick enough you can feel the firmness come in. I would compare the ride feel to that of a Mercedes. A Cadillac is too soft, and you don't know if a road is even there. In a BMW, you feel the road, but often too much. With the Street Grip I felt in control, but did NOT have to experience EVERY bump anymore.


WELL DONE RIDETECH!!!!!

PS...Schwartz was GREAT to deal with too

It's definitely a great system, I saw it in action when Ridetech swapped the system into a red 68 Chevelle convertible at the Scottsdale Goodguy's. There was a several second difference in the autocross, and the car just looked so much flatter in the turns. I'd definitely consider it on any more basic cars I might do in the future (I have their full system for my 71 Firebird).

Great news. I am installing a StreetGrip system in my '55 Bel Air next weekend. I can't want to drive it afterwards.

What shocks were used with the TVS kit? What shocks are being used with the StreetGrip?

Shock tuning is of the biggest factors that effects ride quality on the street with aftermarket suspension. Having double adjustable shocks on a TVS or StreetGrip kit would allow tuning either of those suspension kits for optimum ride quality.

Look at ViKing shocks for example. They don't even make non-adjustable or even single adjustable shocks. They only sell double adjustable shocks. Their latest has been electronically adjustable and 4 way adjustable shocks.

Most users of these non-adjustable kits, however, can make these kinds of reviews because either company has their kits tuned one way. The TVS kit could've probably performed just as great if double adjustable shocks were installed and tuned for the car.

F-body--

I had HQs on the prior setup. My main issue was spring rates being too high. I even hated taking bumps with NO shocks installed. The suspension absorbed none of the bump. You cannot set an adjustable shock low enough IF the spring isn't even flexible enough to move the distance required to absorb the impact. I agree shock tuning is important, but there is no way to tune down spring rate.

High spring rates are GREAT for the track, I LOVED taking street corners at over 40mp. It was everything in between that I didn't like, and that NO shock can fix.

It seems counter intuitive, but it's been observed that under damped springs often feel more rough than aforesaid springs with the correct damping.

That isn't to say that a solid bar in place of springs would ride right with better dampers, but rather that there is often a lot of misattribution to spring rates that would actually be fine (or at least much better) with the correct damping.

Here's another question I have. Did you try installing a spherical bearing in the front spring eye on the TVS leaf? Installing this would've freed up motion/bind by letting the front of the leaf spring pivot on a bearing rather than a bushing.



Ace xp2 has a point that correct damping is key for any spring to work to it's fullest potential.

Since we're mainly talking about leaf spring suspension on this thread, I'll mention Dave at Pro-Touring F-Body. He often, especially on this forum, doesn't get enough credit on the performance suspension scene. He would be one of the first to tell you that you can comfortably run high leaf rate springs on the street if you have fully adjustable shocks. Many of his customers are running his competition (high rate) springs on the street and they also have fully adjustable shocks.

According to the website, the HQ are only rebound adjustable. Correct me if I'm wrong but there is not separate rebound and compression adjustments for those shocks. They aren't able to tune like a fully adjustable shock.

Sorry that I'm questioning facts in this review rather than jumping to brand conclusions. There's a lot more to it for me than simply StreetGrip is better than TVS after 5 miles of driving.

hotrodneb
07-23-2016, 03:30 AM
Here's a simple answer-----

I changed NOTHING BUT the springs (already had HQs on) and NOW I like the ride!!!!!! I HATED the ride before----PERIOD

Jeez-----the only reason for the post was to comment on how I like the Streep Grip. I don't need a hassle about all that I SHOULD have done OR did wrong. I F'n tried everything I could. And YES....it is "rebound" that is my main objection. The spring rate was SO stiff that the rebound could NOT be adjusted to my liking. I am looking for a SPECIFIC ride. To compare to OEM rides, no Cadillac, no BMW, but something close to a Mercedes ride. ( I drive ALOT of cars)

AND-----I didn't say ANYTHING was "better" than anything else. The Hotchkis stuff is excellent for what it is designed for. I NOW own a suspension designed for what I want out of MY car.

Thank you

PS--(F-body) The rear leafs are listed in the classifieds

Sorry to aggravate you with my questions hotrodneb. You're right, you don't say "better" but you surely make it out to be in the nature of your comments. I, however, think you might be confused by rebound vs compression tuning on shocks.

Have you upgraded the control arms on your car? Tubular control arms with low friction ball joints and greaseable pivot points free up front suspension articulation. This hasn't been mentioned on this thread but would play a major role in suspension feel with either the TVS or StreetGrip kits.

I have the TVS springs so I don't need to buy yours. I'm actually going to switch to higher rate leaf springs from Pro-Touring F-Body. I have various reasons for that but I'm not trying to make this thread about me and what I'm doing.

PS hotrodeb - I have driven a lot of cars too. I've driven vehicles for a shop that serviced 10+ dealerships, worked as a mechanic at a luxury sports car dealership and have even worked at a restoration that specializes in vintage Italian cars. Your general point of Mercedes vs BMW vs Cadillac is kind of bogus if you ask me. All those companies make 2 door sports cars but also SUV's. Of course a Cadillac Escalade ESV will ride much different than a BMW M3.

This is a tech forum where people discuss subjects but it's a shame you obviously don't want to have anything to do with that. Sorry for trying to look at this thread more in depth and I will get off your thread now.

For anyone else looking at this thread, please don't use this as an example to base proper judgement on an aftermarket suspension kit for street use. There is no proper analysis here. The first post doesn't even say what car these kits are installed on. Spring "rate" does have a factor in the overall equation but there are plenty of other things you can address to free up suspension articulation.

I like subjective views of products. Thank you. I too have the TVS system and think it's a bit too harsh. On smooth roads it's great. On typical California rough ass roads it's a bit too stiff. I actually got closer to what I like ditching the IAS shocks I had and switching to Gabriel gas shocks.
I still have too much bump steer and am considering the true turn system.

FYI, i don't race, i drive my LS1 1969 Camaro daily. I live under 1800 rpms and put 15k miles per year on the car.

Another suggestion, get newer car seats! My bmw m3 seats made a world of difference driving 600 miles in one day!

My first thought is WTH???

Dude, he offered a general review on how his car responded for others to consider. What's with the third degree?? Hotchkis or someone else paying you to come on here and push product? It seems your posts have a constant theme...

Why don't you stop the hard sell when it's not wanted.

ace_xp2
07-24-2016, 01:17 AM
Heh, looking through his posts that's probably the case.

Without knowing the actual rates and figures of both sets of shocks and springs it's hard to say what's going on in either case. Which is often the problem with just buying kits from any company, be they Hotchkis, Ridetech or a China-by-night, without all the data on the table you're often just clutching at straws about how the system is working. And while changing to a new one may bring what you're seeking, it may not necessarily be for the reasons you may be thinking.

I really wish more companies posted complete information on the whole system, though they likely figure once you know enough to understand the data you'll probably just build your own.

I just want to be clear to you guys...I am not being paid by anyone! I'm sure those of you who may be thinking that have been looking at my most recent post history in the "for sale" section. Yes, I have written commercial-like posts in the "for sale" section recently but I mainly do this to minimize questions relating to what I am selling. If you guys have sold used parts on here, then you know people often ask things like, "what's the part number?" or "does it fit my car?"

Did you guy see my sway bar comparison thread in the suspension section recently? I wrote this for everyone on the forum to see a fair and unbiased test. This even highlights the pros/cons between all the brands mentioned in this thread. I want to emphasize that I wrote this in the most unbiased way I possibly could!
https://www.pro-touring.com/threads/121121-70-81-Camaro-Firebird-sway-bar-comparisons

Again, I am sorry for being a fire-starter on this thread. I said I would get off but I can't let it go by without it being known that I am not being paid by anyone to push products. Everything I do is self funded and I do my own work at home. When I sell parts I'm not using, it's to fund the next project on getting my car together. Cars and going fast are my hobby like many others on this forum. I haven't been up to par lately with posting my own tech threads or updating my build thread but after this I am now motivated to prove I am unbiased. Please stop the accusations!

How do the leaf springs mount with a multi spring rear? As I believe they are mono style ?

hotrodneb
07-24-2016, 03:33 PM
The kit came with provisions to mount to either mono or leaf perches, and hardware. There were correct spacer blocks included for both. They also came with new speed nuts and bolts for the front spring mounts. I bought the delron shackles too, worth the extra little coin. Full instructions too in the box.

I have the TVS front and rear springs with there latest 1.5 shocks. I have the guldstrand mod, stock arms with graphite bushings and huge Espo swaybar. Pretty much feel the same. Rides great on smooth road, and can corner great but not many smooth roads in my state. I have slowly been de-tuning the car to make it a more pleasant driver. I'm getting old and the ride is just a bit too harsh for my liking.

Its very jarring hitting bumps in the road. It doesn't really absorb the bumps as much as it rides up on them. I read about the hotchkiss front A-arms in another post. I would like to stick with the same brand instead of mixing parts but it comes down to a grand for new A-arms or put a grand in another direction? I was considering just changing the front springs with the ridetech dual rate ones. I'm still don't know about the fiberglass read leafs behind my 455.

I appreciate the review and the other comments on the Hotchkis stuff.

I would be very interested in this kit, IF there were spring rates posted.

hotrodneb
07-26-2016, 03:28 AM
The tag on the rear leafs said 175#, but they don't feel that heavy. I am certain they are progressive UP to 175. Hotchkis lists their rates at 150/180. I took the "overload" out of my Hotchkis to make them a 150 constant rate and they still didn't have the initial flex that the StreetGrip does on the initial hit of a sharp bump. To me they feel more like a 125/150, with the 150 coming in fairly smooth and relatively quick. Stock rear spring rate is 115 constant.

Here is an experiment IF you want. The Hotchkis leafs are 3 springs, with the last spring being an overload that makes the higher rate. The final piece is a 6" piece that fills the cavity in a multi-leaf perch. I swapped the stack so it went, leaf-leaf-spacer-overload. This made the overload come in MUCH later IF at all. It improved my ride feel in the direction I wanted. THIS experiment told me that MY driving required a lower spring rate.

My requirements for my car lean more on the touring side of Pro-Touring. YES shock tuning has ALOT to do with ride quality. My limited personal experience has been that "like a house is built on a foundation", it starts with the correct springs for what you want.

What was involved in swapping the leafs? Was it just a bolt in place? (As I was typing I remembered I had a picture)

Would also like to hear more on you impressions of the fiberglass leafs. Are you putting much power to the rear? Any wheel hop issues? I assume you put the rear swaybar?

Rather than all the BS...I would rather see a decent review on the Street grip system. I am thinking of putting this on my BB vert, and could really use some opinions/reviews on how easy the install was, the value at the price point and the level of improvement achieved. At around $2-2500, there are a lot of options out there, but it really depends on what you doing with your car. Mine is street driven, period...SO this system looks like a good choice.

"Viperman"-I can only offer opinions on how my butt feels driving my car now. I am certain there is someone out there who can offer a complete pic/pic and technical comparison. I like the car now, didn't before.

"rohrt"-- Since you provide pics of springs on the floor, you are MORE than capable of installing the StreetGrip. Both springs simply replaced stock pieces with no modifications. (bolt in place) The rear kit came with all possible hardware for both mono and multi leaf perches. I suppose I should have taken pics but it was REALLY hot and I was in a hurry to see the improvement. Total rear swap took me about an hour. (clean car-nothing rusted) There is a vid somewhere of them installing it in a parking lot.

I only started this thread because I hated how my car rode. It handled like it was on rails. Just this week I sold off a high-mile 2002 Eldorado and replaced it with a 2006 Monte Carlo. The Cadillac felt mushy, the Monte solid. My Firebird now has a modern, solid feel that doesn't give me headaches driving through town. It also certainly is NO Cadillac.

hotrodneb,

I would like to know how your ride height changed in comparison to the hotchkis springs?
What kind of power are you putting out to the rear leafs?
Are you using the RideTech sway bar?
Who's A-arms are you using?

Thanks

hotrodneb
08-18-2016, 11:53 AM
1-I didn't actually measure ride height before/after but I believe the Street Grip rides about an inch higher than the 3" Hotchkis lowering leafs
2-Power is only a stock LS-1 You would have to contact RedeTech about max power suggestions
3-Rear sway bar is an Ebay cheapie, front is stock, and I like it
4-Control arms are cheap ebay Chinese tubular stock height knock-offs because I am a broke car guy. I have replaced all the ball joints with good ones.
The control arms have the reversible plugs for caster correction and tall upper ball joints in leu of tall spindles

Great info.

I was just wondering about wheel hop do to leaf wrap and if it was an issue.

So it sounds like you just bought the front and rear springs from the StreetGrip line. I was considering the same. I like my stance with the Hothkis springs, I think my fender to ground is around 25" if I remember correctly with a 25.5 inch tire. If you get a chance I would like to know what yours measures.

Thanks again.

hotrodneb
08-18-2016, 02:20 PM
Yes just the springs, already had HQ shocks

Rear measures 28 and front 26 to ground with 245-45-17s. Josh should chime in here. I think there is an easy lowering method if you want lower.

rohrt
08-18-2016, 07:17 PM
Pretty darn close to mine with the hotchkiss springs. Just ran out and looks like 27 in the back and 26 in the front with my 235-15 tires.

This kit looks awfully familiar to what I pieced together for my 70 Camaro. I agree, composite leafs are FANTASTIC compared to steel leafs. I got a set of 225lb ones and they are super responsive and highly tuneable with rebound adjustable shocks.

I wonder where Ridetech gets their composite leafs from? I got mine from Hyperco.

jknight16
08-20-2016, 06:13 PM
I have Hyperco leafs as well (225lbs) and can confirm they ride fantastic (I have Alston singles). The Ridetech kit is nice because their shocks are great, bushings are an improvement over the rubber ones I have, and the spacers/hardware to install them on multi leaf pads are nice to have all gathered in a kit. I added a Fays2 watts link but that seems to just add unnecessary packaging issues if you're using them on a street car.

kimosabi
08-21-2016, 06:02 AM
I watched the vids on the kit now and they say they are Hyperco leafs.

With a few twists I have this exact kit myself, only that I pieced it together from here and there. The shocks however I would like as mine are KONI Classics, adjustable but not on-car adjustable. Missus likes a smoother ride so if we went for a road trip together I'd have to remove the rear shocks and soften them up three turns.

About the watts link though, when is the limit to where a watts link should be installed to support the composite springs?

jknight16
08-21-2016, 07:34 AM
Re: the watts link, I'm not sure but this style of leaf is used in dirt track cars with very large tires that put far more lateral loads than most PT cars will. I think it's probably overkill, but that's how some people roll. Install the StreetGrip kit and you could always add a lateral locator if you found the need to adjust roll center. I suspect very few have that need.

Liteflex is the contracted manufacturer for Hyperco. Litelflex only does large quantity OEM type manufacturing, they have no ability [nor desire] to deal with the details of a retail sale [tech calls, price questions, fitment questions, etc.] They are the manufacturer for the Corvette composite leafs since 1982 as well as the composite leafs under the Mercedes Sprinter vans and a variety of other OEM applications.
Hyperco only has limited ability to handle retail sales as well...limited to the racing markets they are currently in...circle track, NASCAR, Indycar, etc. That is why we are handling these springs...and all the tech calls, pricing, packaging, development, fitments, etc. The Liteflex/Hyperco leafs have proven to be a really nice performer...when paired with the correct bushings and shock calibrations.

Hi,

What would be the recommended spring rate for these leafs in a 73 Firebird? 175? 200? 220?

I would combine them with Koni Classic Red shocks. Should the shocks be adjusted towards more rebound, less rebound, or just neutral?

The car would do 100% street & cruising with some spirited driving, but I would occasionally have people using the rear seats.

Thanks

Yater
08-26-2016, 09:14 AM
Also, forgot to ask, anyone with a 2nd gen. had issues, or is there anything to watch for, with the proximity to the exhaust tips ?

And can the Ridetech delrin bushings be fitted into a Hacerlo leaf? Do they fit then the stock shackles ?

Hope not to hijack the thread, good that we share the experiences...!

Yater---

Just buy the street grip system. I tried piecing stuff together, it is MORE hassle than you save.

Yater
08-26-2016, 12:05 PM
Thanks for your recommendation.
The fact is that I just need the leafs, since I have already front tubular arms and new shocks on all 4 corners.

Also, if I understood correctly Ridetech specs the leafs at 175 #. But I see some other people with 200 or even 225 #.
Not sure what's best based on the description I made. Any insights ?

hotrodneb
08-26-2016, 03:59 PM
you can buy just the leafs (I did) and the coils. Whatever the #spec....they are the ride quality I was looking for

I have the 225lb Hyperco leafs with Koni Classics set on 5 turns. That is STIFF as heck real solid. It depends how you want your ride, I am gonna try everything from zero turns up until the 5 turns I have now. Koni Classics are really variable(you can feel the differences from each turn when you compress them) so I would say with a 200lb leaf you can taylor the rear pretty much to anything you want just with the Koni Classics.

Worth noting though is that the difference in spring rate from 175 to 225 might not be so much, but the shocks makes a whole lot of difference.

Hi,

What would be the recommended spring rate for these leafs in a 73 Firebird? 175? 200? 220?

I would combine them with Koni Classic Red shocks. Should the shocks be adjusted towards more rebound, less rebound, or just neutral?

The car would do 100% street & cruising with some spirited driving, but I would occasionally have people using the rear seats.

Thanks

We use a 175# composite leaf in the second gen Camaro/Firebird as well. While we do not require that you use our shocks in conjunction with the composite leafs, be aware that the composite leafs react much quicker than a steel leaf and typically require a bit more rebound valving than the traditional steel leaf. Our shocks have a wide range of rebound adjustment so you can customize the ride and handling to your driving/handling style. We have a 70 Camaro that we have been driving to show, taking on tours, and doing some autocross event with. The ride is quite comfortable and the handling is nicely balanced. With a 235/275 Falken tire combination, it can run well into the top half of any Goodguys autocross field with a drive of limited experience [my 17 year old son Andy]. I won't pretend that it would be competitive in the Pro class but it certainly is an impressive combination of ride quality and handling performance.

I had the chance to drive the Ridetech c10 over the weekend. That is the best riding truck i have ever been in. Soaked up every bump i hit. I swapped seats with the Ridetech guy and he took we for some high speed corners. I was very impressed. Looking to do it now on my 78 c10. Buy once cry once!

We have the StreetGrip on our 66 Chevelle Convert.

It was sent to us to test out and I can tell you I have no desire to take it off at this point. The car rides AMAZING and it still handles very well. They truly hit the sweet spot between the two.

We have sold a lot of StreetGrip kits now and the feedback coming in is excellent.

At the price point, there are a FEW other choices but nothing out there will give you the mix of an incredible ride AND great handling.

Let me know if you guys need more info/prices on the kits.

Looking at the parts list for the StreetGrip kit, I'm assuming I can keep the oem front control arms on my 70 Elco, correct?
How soon before Ridetech offers new oval LCA bushings?

Got the ridetech streetgrip rear kit installed on my 69 firebird last week, hoping to do the front this week.

Hello,
according to Ridetech the manufacturing of the oval bushings is on the books but has yet to be done. We can only hope it will be done sooner rather than later. Unfortunately at this time we do not have an exact date.
We will keep you all in the loop once we know it will be available for purchase!
Thanks!

Thanks,Matt. Even though my car's stamped control arms have all-new rubber bushings and ball joints, the arms themselves are 47yrs old. I think my best bet is to save up for some better quality stuff.
