Almost took mine out today, but took the SVTF instead.
I'm not new to the sport, but I'd like some feedback on this particular car, especially if you're running an automatic ( yeah, I know, not the best tranny for this type of thing.... )
I've run mine once this year, and am running again this weekend. But I'm new to the sport, and the current venue has quite of bit a brick wall that is quite intimidating to me , so I left traction control on last time, hehe.
Anyone know a good tire pressure to run on these cars stock?
I've been doing track events the past 9 years.
One year with a T-bird SC the rest with a 93 stang
Havent had my 07 out there yet So I cant say much.
The S197 chassis is way stiffer than my braced and caged
fox. Very good handling car stock. Im looking forward to
see how far I can take the brakes.
For tire pressure I would start with 28-30 psi for street tires.
Really? Admittedly my experience has been with WRX's, but tires are tires. We'd start at 40 psi and go up/down a psi or two to balance out the car. This is with summer street tires. I'd *guess* with rear wheel drive dropping the rear psi a bit would help with traction under throttle.
When I ran my contour, I ran the auto in 2nd gear and it was perfect; plenty of torque everywhere (well, for a countour).
You gotta remember that the tires PSI will go up around 5-8 PSI when
they get warm. So after a few laps your tires will have 45 PSI in them.
Bet you wear out the center of the tire fast.
For autocross there's plenty of time between runs to balance tire pressures. We're also only running ~45-90 seconds at a time, so heat doesn't build up as much. A couple psi heat increase between runs is normal.
Guess im more used to the large tracks I did'nt consider the question being for
parking lot type racing. See I mainly run a 4 mile track for 20-30 min
so tire PSI changes alot from start to finish of the race.
