1969 Camaro tru-turn - Page 23 - Lateral-g Forums

Rubbing while busting nuts around the race track is different than rubbing while pulling up a drive way into a gas station or burger joint. Mark doesn't seem like a compromise sort of guy, what suspension is he using on the front of his car?

If the tru-turn is for race cars that you trailer to the autocross, so be it. My expectation was that it was going to be 95% usable. For what it costs to buy a full ridetech suspension/steering box/ and then to roll the fenders and cut up the inners - you aren't too far away from what it costs for a full subframe designed for 275 tires.

What did you end up with Camber #'s on your alignment?

glr0212 · #**223** 03-29-2016, 03:36 PM

I started here

Camber -0.48

Caster +3.77

Toe in 0.03"

Then I took some measurements and added shims to get another degree of camber. 1 degree of camber is equal to roughly 0.5" of tire movement at the top. The other issue i had when trying to figure this out was turning radius. Turning radius can be determined by wheel base/tan X, where X equals the max angle the tire can turn from centerline. So a stock chevy camaro can turn roughly 29 degrees which equates a radius of 18.7' or 37.4 feet curb to curb.

With the tru turn i estimated i was going to be somewhere between 22- 24 degrees best case scenario, which is 44 feet curb to curb. Maybe I could live with that if i felt comfortable the tire wasn't going to live on the fender lip.

I guess they fit. Just for the record...all GM metal. Is it a tight fit... sure. The 1969 Camaro is much harder to fit the 275s if you want to run the car low. We used an 18x9.5 wheel with a 5.75 bs. We rounded the corner of the sway bar end to eliminate the rub. Still way cheaper then a Sub Frame.

Ridetech front suspension complete $3150. Uses parts to fit a Camaro headers, brakes steering connection and ect.

Aftermarket Sub Frame $7500 plus headers, engine mounts, brakes ect now we are north of $10000.

What (if anything) did you have to do to the inner fender lip on the 69 to get the 275s to fit? I have the same set up on my 69 firebird, but have 6" backspacing. I am waiting to a spanner wrench from Josh so I can get the front of my car out of the weeds. I would say that my car is currently nearly 2" lower in the front than the 69 pictured. I moved it from 1 garage stall to another last night and the tires rub when I get near full lock, but I think most of that will be taken care of when the front is raised up to ride height and camber is set to around 2 degrees (the car will see a lot of track time).

Beautiful car. What is the ride height in the front?

Smittys67 · #**227** 03-31-2016, 08:57 AM

I do not know the measurements for ride height. We did zero modifying on the sheet metal.

When you say "I guess it fits" What do you mean?

That it works on a car that is street driven on a regular basis with no issues.

My rim/tire might just kiss the muscle bar end at full lock. I might have to round off the front corner of the bar end for added piece of mind. The back of tire also just kisses the sub at full lock. I am running 6" BS, so that might contribute to that a little bit. There is a short section of each inner fender lip that might need some massaging, but I won't know for sure until I get my coil overs adjusted for ride height.
