Installing Tru Turn

[MrQuick]

Hi Mike,

How does it feel?



Back notes, Brian @ Dreamspeed was able to finish up the car.

Allen and I found that Dynatech headers fit kick ass and fits the ridetech Tru Turn system with ZERO issues, plus having a 1 3/4" to 1 7/8" step is an added bonus. They are also designed to fit around the 670 boxes. The Dynatech stuff is built very well.

Maybe Mike can post some pictures.

we were able to fit my 18x10 6.875 back space rims with 285/18's. I think a 6" back space would work great.

Vince, what is the ground clearance like on the Dynatech's? I'm trying to figure out a set of headers for a 67 Camaro Chassisworks Subframe with power rack and SBC.

Vince,

Are you saying the 6.875 backspacing really worked? That is much, much more than what ridetech recommends. I would think that the tires would rub bad at full lock and would severely limit turning radius. Is this a stock subframe?

I just installed the ridetech TruTurn and complete front suspension system on my '69 and for the last 2 days have been measuring for new wheels. I borrowed an 18x10 with 5 7/8 backspacing and 275 tire. With the Ridetech recommended 5 3/4 backspacing, I do not see any way I could get an 18x10 with 275 tire on there. With a 3" drop, it would have severe rubbing of the fender!

Can we see a side shot of the ground clearance the headers? Also what oilpan on on that car?

[Rileys68Camaro]

Gary, on the 48 Hour Camaro, and all others, you have to trim and reweld/rework the inner fender to get a 10" wide wheel in there. Must use their sway bar set up as well.

[mdprovee]

I have only driven around town once, I don't notice a big difference, but autocross starts in a few months. I will know more then.

The new Dynotech headers fit nicely with tons of room. I will try and get some pictures tomorrow from the side. I am just waiting for the tread on the front tires to get worn off, then I will look into getting wider wheels and tires. Just from looking at what i have, a 8" wheel, I believe I could get an inch wider on the inside, but not on the outside without rubbing, or alot of inner fender mods. I will try to go to a 9" wheel.

[MrQuick]

We didn't get to drive it with the 285's, We got put on another project and it was finished by the other guys. We did drop it all the way down and turned the wheel lock to lock. It wasn't too bad. Wish I had more time with it to experiment.

The wheel/tire fitment kinda surprised us. It fit better than we thought it would. That size may rub the frame at full lock, but you're not going to be at full lock too often. I about crapped myself when I put the wheel on the car and it actually fit. And this is with a stock subframe with DSE uppers and lowers. A 275 on a 9" rim would be a good fit. I too wish we had more time to check it out and get a real determination on max size possibility.

I knew it, you slob!@!@ with a tad more camber too.

[Huzzah!]

So there's a bit more work to get wider tires in the front than what I thought. Exactly how much work had to be done to fit some say 275s. ?

[MrQuick]

nail the back space....

I see that was already said. My mistake. Carry on gentlemen.

I will have to take picture tomorrow.

Vince, anytime you want my car back to investigate its yours. I will need that investigation for myself also.

[Bad94]

At RTTH's Bret wanted me to take the 48 Hour Camaro front wheels off and put them on my Nova, and Let me tell you, they fit, Rubbed at full lock and thats all. I even have my car really low.

After talking with Bret, the novas have a little bit more room then the camaro does.

I did drop 2sec off my tire with the 275's over the 225's that i had. With the 275's up front and 275's out back, i was able to steer with the throttle.

no worries, some things are worth repeteing and i don't mind typing as long as you don't mind reading. lol gentlemen.... y thank you.

Thank you Mike, As soon as I find another shop i'll have to get you back in for a test and run.

do you recall the back space on that rim?

[Garymac69]

Those wheels on the front of the 48 hr Camaro are supposed to be 5 3/4" backspacing. That's why I was suprised at the amount of rubbing when I did my test with the 18x10 with 5 7/8". At a 3" drop, that 275 rubbed the bottom of the fender lip at around 70% turned, both left and right direction. I was prepared to do cutting on the inner fender, but not mods on the fender lip and risk damaging the new paint job. I really wanted 10's on the front, and I still think it may be possible with more backspacing. The car is on jack stands (I sold the old wheels) until I get new wheels, so I need to finalize the order for the new wheels very soon. It's looking like I will have to go with 9's to get a little more room.

Hi Gary,

The thing with a 6" + back space is there is less outer rim to hit the lower rear fenderwell/fender lip. We have another car that we are running tons of Camber on and his rims hit big time. 5.5 BS. With the 6.875 BS rim and 2" wider the tire clears by 1". Never comes close to the wheel wells but does hit the frame at full crank turn.

Like I said as I find another shop i'll do more testing with this set up.

Hi,
Could you please post a picture of how much the Dynatech headers hang down below the subframe?

[mdprovee]

Sorry took so long for pictures.

Headers give great clearance for the Tru Turn system. They do hang below the subframe, about 1/2" on the drivers side, and about 1" on the passenger side. Nothing more than the Super Comp headers from before. They also clear the steering box with dimpling, and tons of space on the passenger side.

They also clears the pan which is the Champ road race pan, also no problems with the Tru Turn system and pan.

ridetech was very helpful in dealing with me, and gave me great advance. I hope to start pushing it soon.

[anthonys 69]

Did you have any problems with the alignment. I have a 69 camaro stock sub frame and would like to put dse control arm and tru turn system. My vehicle will be a weekend cruise vehicle so id like the tires to last. Dse was not sure if I would have camber issues. Thanks..
