Cool. Do you think the difference is paramount due to me being on slicks ?

Purple crack are another category completely unrelated to this entire conversation. IIRC, they run a lot lower pressures than the standard street tire. plus, what other tire can you stuff a 245 onto a 6" wheel and it work just fine?

This is good stuff for me. I'm sure there's a learning curve in autox, but that about the tire pressure in different tires causing a bigger difference in handling than what I thought is surprising to me. I knew tires had an impact on curves, just didn't think it was that big that tire pressure was a differentiating factor. Glad you guys helped shed some light for me.

And it's amazing what just 1psi can do. Some of it is butt-dyno type stuff, but if it's close that one last tweak can really get it there for you. That being said (and I'm a bit ashamed we didn't mention it before), if/when you start making adjustments... only do one end of the car at a time. Don't bump up the fronts and drop the rears at the same time. Much more likely to overcorrect that way. Same thing with any setup changes you make. Only do one end, and only do small increments (unless you're REALLY sure you missed the setup by a lot). -------------------- |

Also the #1 adjustment is to the loose nut behind wheel. Seat time, seat time, seat time are what get you faster. Burn through a set of tires, then worry abotut making car adjustments.
Also, in Auto-X, tires are the second most important item on the car. Motons, 500hp, bg sway bars etc mean nothing if you can't get the tires to grip the surface worth a crap. If it was me in a J2, I'd search for some light 15x7.5" wheels and some 225/45/15 RS-3 or Rivals. You're stuck in a crap class (STC) so you will get destroyed by the 89 Civic Si's because they're stupid. It is what it is..... just go have a good time and get yourself as fast as you can. -------------------- Founding Member of the Indiana Chapter of the Teeny Weeny Club for Secure Adult Males

Seat is very important. Also having someone ride with you and let you doing wrong will also help. -------------------- "This may be true but it is a chrysler sebring which is synonomous with being a p.o.s. car.

Yep. don't be afraid to ask questions. Many "old timers" are more than willing to help you get started and offer helpful tips. There's not much "Secret" in auto-x.
