1967 GTO project thread

Heyohhhhh...look what was on my doorstep when I got home from work this morning!!!

New ridetech smoothbody HQ shocks with 24 adjustable rebound settings. Bret Volkel made me a deal here a week or so ago when I was asking for feedback on them in the suspension section. Here is what he said....

How about you try them and write a review? If you don't like them, put that in the review and send them back for a full refund. When you call the shop, ask for Darren. I'll share this offer with him.

I'd say one of the reasons you've not seen any feedback yet is because the harsh weather all over the country has kept everyone's cars inside. The HQ smoothbody was not released until later last year...sale took off during this winter, but many of these cars possibly have not hit the road yet this spring.

How can I pass that up? I basically get to try them out risk free as long as I review them on here and ill stick to my end of the deal. It made my decision easy. It was between Varishocks and Ridetech HQ's. If I run these and hate them, I can send them back for a full refund. From the Ridetech love I see around here though, i'm guessing I probably wont be sending them back. SWEET! Thanks for the offer Bret!

Well I installed the HQ's the other day. I talked to ridetech and they were pretty stern that I should be mounting these through the lower A arm hole and not on top of the spacers. It could have messed with available wheel travel. I had to get the die grinder and carbide bur out and do just a hair of clean up on the SPC lower A arm and spacers. Maybe a minutes total grinding on each lower arm. The HQ's just wouldn't fit through. I probably took out less than .080 total between both sides on each arm. I really just cleaned it up and they slid right in from the bottom. Mounted up with grade 8 hardware and that was it!

After a bunch of reassembly I took the GTO out on the first shakedown drive. I haven't even gotten an alignment yet. I just used a level and made the front wheels level and pointing straight. I probably logged 15 miles. My first impression....this thing handles awesome and was/is worth every penny iv'e stuck in it and every hour put tward it. Here is me initial reaction to the short drive I took it on today...


-I can now make a full left turn where I couldn't before with my old jacked up frame.

-I have no ackerman shudder on sharp turns where I had it pretty bad with my other frame

-It feels like its glued to the road and I don't even have an alignment in it yet let alone good wheels and tires. Against my better judgement, I took some pretty hard corners and a long sweeping left hand run down an interstate, it never felt out of control and it felt like it had a lot more in it if the tires would hold.

-The ridetech HQ shocks/SPC springs must really like each other. I have the 24 position shocks at 12 clicks in the front and 8 in the rear. The ride quality was super smooth and much better than the Bilstiens/stock springs I had before. I think I can make it better with some tuning after my alignment.

-The ABC aluminum body mounts/SC&C isolaters were not noticeable at all. I heard no squeaking, the ride quality was great. In fact much smoother and quieter than the stock springs/bilstiens/rubber bushings.

My only issue right now is ride height and this is where coilovers would shine. I'm off from side to side by about 1/2" in front and 1/2"-3/4" in the rear. Iv'e swapped rear springs around and that did nothing so it cant be a rear coil spring mismatch. I looked at the front springs and they are now sitting in their pockets in the frame correctly. I loosened everything up, removed swayabars and shocks and cycled the suspension. There is not a bind anywhere. Its smooth as glass and well lubed. The suspension is just off. If I get a 1/2" spacer in the rear for the driver side rear, I think it will clear most of the problem up. If i'm within a 1/4" side to side i'm calling that a victory for a 45 year old car.

Any other suggestions on where to look on my suspension for ride height discrepancies? I did find that the driver rear spring is compressed a half inch farther than the passenger side but i swapped springs around and that did nothing.

all suggestions are welcome.

A couple of shots...

Out with the new...in with the really new??









All back together where we started!! It was a huge undertaking and im still working out the ride height difference side to side but its good to have it in one piece!

Nick great write up and review.

Did you drive the car with the Bilstien shocks and the new suspension hardware first before driving with the HQ's?

You said the ride was not harsh. I assume the potholed roads are the same in Waterloo as in CR. Any further comments on the ride quality over our crappy roads?

How much drop did the SPC springs give you? I think they are rated at 1.5 drop correct? A bit hard to judge the ride height at that angle.

Nice to hear the solid body mounts are working for you. That always seem to be point of varying opinions.

What size sway bars were used front and back? Was the back sway bar the one that SC&C sells, that is adjustable?

No unfortunately I did not. I should have though. Again the ride quality is much better though and I havent even messed with the shock settings. Im at 12 in the front and 8 in the back.

Pot holes are terrible and ride quality in a Caddy up here sucks. Ride quality is a relative term given the roads are just horrible. I can say with certianty, on a smooth open surface its awesome. On potholed roads its pretty decent though it is a 45 year old car. Ill be messing with settings and logging ride quality from now until I swap to my 18's later on this spring and keeping track of what I think and write it all up later on.

More than I thought they would. They are lower than my stock springs with 1.5 coils cut out and I have the maximum amount of spacers in there. This is a common wish I think that the springs were an inch or two taller. If I took all the spacers out my headers would be on the floor.

Nice to hear the solid body mounts are working for you. That always seem to be point of varying opinions.

Again it was just my first impression but they seem to be a non factor and supposedly a huge difference maker for handling quality. It could be the little Savitske isolaters killing any NVH coupled with ridetech shocks and SPC springs allowing for the smoother ride? The way I see it is that its kind of like welding the body to the frame and making it a solid piece allowing the shock and spring to completely dictate ride quality? Its basically like driving a unibody car? I dont know . Its just a thought. I'm going to pay close attention though and write something up about them later on this summer after I log some miles.

What size sway bars were used front and back? Was the back sway bar the one that SC&C sells, that is adjustable?

I think the front is 1-1/4" and the rear is 1"?? I cant remember exactly but they are the bars SC&C sells. The rear bar is adjustable. It has 3 settings. I'm going to mess with them too eventually. The loosest one/ farthest out is street. Ive only used this one so far and the tightest is for autox/roadrace I believe. Its a very nice bar and they made a huge difference last summer even with the stock springs and A arms still in the car.

Love it, my favorite year for most cars... I wish my tempest was this clean...

Thanks! I'll be checking in on that tempest build!
