Front end specs

tj310 · 03-18-2011, 10:38 AM

Stock settings work fine. As far as jacking up to set alignment, car should be setup sitting at the same attitude it goes through the traps. Our car is set at 3* positve caster 3/4* positive camber 1/8 * toe in. ...Thanx Trevor

Specs from a couple of top chassis builders: 0 camber, 1/16-1/8 toe in and all the caster you can get as long as even from side to side. All this is at ride height at speed.

That is what I have always used.

With "all the Caster you can get"... how does a car handle when you get on the brakes -Hard- at the finish line to scrub off ET or drop the front spoiler to trip the beams. I've always thought a lot of caster (too much) causes steering problems when you are hard on the brakes.

I may not run fast enough for that to show up. LOL

I don't see how "all the caster you can get" would cause any "straight line" steering problems, even under hard braking, as more caster only makes the car harder to turn....
That being said. I'm not an expert at front end alignment, so I could be wrong....

Adger,
I run as much caster as the car will allow, and make the right and left evan. I use zero camber and 1/16 in on the toe setting. I do not have any problem at the top end braking. I think my car uns faster that yours.

Thanks..
I hate to be so anal about this steering/ front end adjustment, but in the past the front end/steering caused a crash for me. My car did real well with the set up it had until I decided to have the bump steer/ toe steer(showed up in videos) corrected by a well known shop. The car came back to me out of alignment, regardless of what the guy that did it says. I had been working on it trying to go to the Sports Nat.'s.. I finally got in touch with him (he was at the race I wanted to be at) and he has given me just about the same specs as you guys. So, I guess I'll forward, pun intended, with the alignment.
Thanks for all the input.
