View Full Version : Celica and the odd "oversteer" as well as mod concerns

i know under OR oversteer are both a bad thing

but i have noticed that when going through slaloms the celica's rear end steps out.

back when i used to think drag racing was fun..the rear end got VERY squirrely under braking after a run on the street. (i dont do that anymore)

what kind of handling setup is preferable?

im running stock shocks, eibach pro kit rmm front TRD rear tower brace
and 17 inch volks on kumho ecsta 712


also...what kind of exhaust would give me decent torque

and i may also be getting supercharged or some sort of FI (hopefully an SC because I like still having a useable powerband rather than drag race style power)

i ran my last autoX on straigh tpipe.....and there was a noticable loss of low end

i also had too low tire pressure as i discovered
running only about 34 psi :(

any advice?

In general, like you said, you don't want under or oversteer...a neutral setup is preferable. However, it's not easy to find a setup that's going to be neutral over a wide range of situations, especially with a really front-heavy car.

The key to what is preferable is what you like and what you can learn to predict and control. Personal driving style can probably affect handling characteristics as much if not more than suspension setup. The rear-end getting loose in a slalom is probably more driving style than anything. (although there are certainly things you could do to the car to tighten it up...stiff front shocks, rear toe-in, etc.)

As for exhaust, I wouldn't expect to gain anything worth the bang/buck there.

In the last 2 years, I've had my Celi aligned 5 times. Basically I've found that more negative camber is better than less for autox situations. I also used to run zero toe all around, but at the last autox found that 1/16 rear toe in improves transitional stability and makes lift-throttle oversteer more predictable.

Running anything less than -2

I also recently switched back from zero toe in the rear to 1/16" toe in. Noticed the same things Erok did.

I ran GS last year and you obviously are not in a stock class. I run 225-50x15s with -1.2 to -1.5 camber, 0 toe. I'm most comfortable right now with 39psi front and 33psi rear. I don't have tail-happiness unless I lift from the throttle or oversteer, generally. Smooth inputs and transitions are a must (I don't practice what I preach much, though *grin*).

I have no idea what kind of experience you have at AX, but using the above I truly think all the rest is driver. Remember (if new) to run against yourself not others in your class. I *HIGHLY* recommend an Evolution school if you've not had the pleasure and enlightenment of one yet!

Other than that, there are 3 key things: seat-time, seat-time, and seat-time!

Peace and good luck!
