I see other much heavier cars with stock OEM setups and non high performance tires putting down twice as much Hp as mine without this issue.


I am using my left over z1's for streets only.

I understand that, but in this region you have pro teams so you have to be doing 9/10ths or better the entire time to have a chance of winning. We are running about 2,350 without driver.. on 205/50s up front and 195/55 in back.
