Hello fellow ES owners. I have a question. In a week and a half or so I am (at 50 years old), going to Autocross for the first time. I am stoked. My question is, does anyone have any advice on what tire pressures I should be running for the event? Front and rear? I am using the car with stock tires.
I have already test-driven my Sport with the tires & wheels on an autocross course.
The best tire pressures I found were 34-lbs. (cold) 38-lbs. hot (front) and 32-lbs. (cold) 34-lbs. warm (rear) - you won't get the rear tires hot.
The OEM tires, just aren't very responsive to quick steering inputs and definitely are not very grippy....
I purchased another set of rims specifically for autocross use. TSW wheels 17" x 7.5" wrapped with Hankook RS4's in a P255/40ZR-17 size. Optimum tire pressures for the RS4's were 32-lbs. front (hot) and 30-lbs. rear (warm).
All tire pressures were set, using a laser tire pyrometer gun to get all the readings.
Please let me know if you experience a "severely-delayed" throttle response to the engine or just absolutely "no engine power" coming out of a sweeper or corner when you apply the gas pedal on the autocross course.
I shutoff the "traction & stability" control settings on it before going out on the autocross course and experienced both of the symptoms as described above.
Thanks.
