Yes, I understand what you're saying, thats why i set the psi on the rears higher than the fronts. Most people think that if the psi is too high, it will result in wheel spin or slower launch when its actually the driver who causes wheel spin. At the track I looked at other cars and alway notice that their front/rear tires are low on air. When I asked, I get response like 20psi, 25,psi, etc. When I tell them I have my fronts set at 45psi, they go
and look at me like I'm stupid. Then they go
when they lose to me.
My front tires only need enough flat contact to the ground for a good launch. Notice how I can still pull a 2.1 60' with 45psi in the fronts. The main reason why I set the fronts to 45psi is for faster acceleration, better top end, to save gas
Notice how my trap speed is high
