I was wondering what psi my front tires should be set at and the rear when I go to the track??? BTW..they are stock 15" tires..actually they're kuhmo ecsta supra 712's but stock size..thanks..

I would try between 20 - 25psi. The lower tire pressure will increase the contact patch for better traction durring your launch.

Yep .I've heard 20psi.

 

[DefiantGSR]

20 psi

20!?..oh my..dat seems really low..I was thinking more like 30, isnt 20 kinda dangerously low?..Thanks for the advice though..i'll try it out.If you lower ur psi I know that you'll grab harder on the lanuches but would it affect the acceleration/speed after the launch??

Another question. Would it be a good idea to bring a bike pump or something to pump the tires back up for the drive home?

 

[TurboGsR]

22 psi

bike pump wont handle it. pick up a small air tank. if you ever go to an auto cross event, you'll notice all the drivers have one. plus get a precision air guage... the stick things aren't accurate

 

[DefiantGSR]

just drive to a near gas station after the track

I dropped mine to about 22psi on my track day. I didn't notice a bit of difference...Then again, I was throwing WAY TOO MUCH giddy-up onto the accelerator on those launches, so maybe I'm not the best to answer! Especially since I have all-weather XGT-V4's that have pretty solid side walls, so they didn't flex very well.

i run around 25, depending on track temp. But the best thing ive done for traction, belive it or not is polyurethane motor mounts and a chain from the engine to the core support. It works! It took all the wheel hop out of it and really let me lay it down.

how much does your dash rattle now that you have the polyrathene motor mount bushings in? Thinking about getting them, but I CAN'T STAND rattles. I can deal w/ small rattles, but w/ anything large, ...

they handle harmonics fairly well, but then again, i wouldn't really care myself. I really didn't notice much change. It still had some wheelhop w/ them in, so i put a chain on the engine, stopped it almost compleatly

nope after you get going your tires will expand to what they normaly are from the cyntrifical force...but the thing is 20psi is to low because once they expand the pressure will be even lower like 10 or at best 15psi...so if you have to stear or anything in an emergency incidence then you are screwed...i drop mine to 25psi

 

[Integraholic]

I put mine at 20 to 19 psi.
