First time on r comps.
The front end is chattering in the corner, get on the gas and it fixes it cant carry any entry speed because of it. Tires are BFG R1's, pressures to start are 30F 26 R, end of session 34F 33R. I took the rear spring rubbers out and lowered the rear. The ass end was all over the place, this helped a bunch and dropped 3 seconds off the lap time. Go up or down on pressure or what? You enter the corner, the car starts to push and the tires chatter, skip, gas pedal pedal helps it. All input welcome. My new best is 2:02 at NOLA. |

Tire pics. They were rotated at the end of day 1.
What is the line forming on the right side of the tire? This the LF.
