What tire pressures are you guys using. I can't seem to get a pressure setting I like. I am running 215 17 up front and and 255 17 on the rear. The car has gone from a push condition to an oversteer condition. I have 36 psi at all corners and 34 front and 36 rear(does this tire like to be at 32psi?). Please note that I am running an 8" rim up front and 9" on the back. Steering response is better than stock, but I having trouble figuring out tire pressures to run or if the front has that much better stick now and I am over driving the Car now? This might also be the fact that this tire has a lot more tread compared to the S02's when new.

I do a lot of Auto X and HPDE, but this tire set up has me miffed?

Any recommendations would be appreciated since one idea passed to me was to remove the rear sway bar to soften the rear and give me more grip.

 

When I ran MXs I ran 225s and 255s at 35psi all around and the car was perfectly neutral. I was running a saner front bar, though....I doubt you're going to make much of a difference by playing with a few PSI. If I was you I'd go in for an alignment before experimenting with anything else.

 

What front sway bar are you running david1?

 

I still have the stock front bar.

 

For me a 225/245 R18 Kumho MX combo was quite balanced, but using a stiffer (Muz) front sway. It was not the ultimate street tire but very good value for money.

Why don't you try disconnecting the rear sway for a track session and see how it feels. It's cheaper than buying a new front sway...

 

u talking about cold or hot air pressure...

going from 41 hot to 36/35 hot made a WORLD of imrovement.

First post represents cold pressures.

 

Even if you start at 10, 20, or 30 cold, your cold pressures are going to go up... end of discussion. The only number that matters is the hot pressures. Find out what works best for your tires and aim for that number. Add or remove air from the tires after every session to maintain your target number.

 

Seems that's why the handling is all mesed up. That's way too high. We are all talking hot pressure in the 30's. Tires will gain even >10 psi as they get hot.

You generally have to start with bleeding air from street conditions before you track.
