We used to run 7 LR and 12 RR,,,several weeks age we changed to 12 LR and 15 RR and the car sems more stable. That is with two different cars and the same results.

2400# car (no driver)
RR 11.5
LR 10.5
RF 12
LF 9

I float around from these but not much. Works for us. I've mistakenly run higher in the rear before and that was way off. Also just for kicks - check you pressures after a feature some night - I've seen these pressures as much as 6# higher.

Just rememeber - we're not comparing oranges to oranges here but I'd say your in the ball park.

If you check your tire pressures after the race, you can see if the tire has to much air or not enough. Then take a temp guage and read across the tire. If the temps are equal the the tire has the right air pressure. If the center is higher to much air. If the center is lower not enough air. We do this as soon as we get off the track everytime. Its the only way to see what your tires are doing. Then you can change your starting pressures to fix the problem next time. We run nitrogen mainly. Heats we go 10lf 12.5rf
9.5lr 10.5rr
features we go 10lf 12rf
8.5lr 9.5rr
