Alright fellows, this is a great site.I run on a 3/8 mile track with 12 degree banking.i run springs, lf 100 rf 1300 lr 250 and rr 225. 54% left side weight, 51.5% rear weight. 1 1/2 stagger front and rear.air pressures are lf 16.5 rf 20 lr 16.5 rr 18. tire sizes are lf 27-15 rf 28-15 lr 28-15 and rr 29-15. With this info, how will this thing handle and do i need offsets and ifso which corner(s)? If you need any more info, please let me know. Thanks, Johnlj68

We run a very similar car, but I'm concerned about the low tire pressures. Our tire rule is any 70 series street tire. We plan on running a Lee Turbo tech on our 3200 lb Nova @ 1/2 mile clay moderately banked track. We can run a bead lock on the RR. What pressures should we start??

I agree with racer17. I won the first four out at my track last year and got called a lier about running the pressures between 18 and 24. By the fifth race others started trying it and noticed what I had discovered. An older racer that builds chassis in my area told me how to tell for proper inflation on the right side. He said check the dust line create on the outside of the tires and raise the pressures till its about a 1/8 inch below where the tread starts on the sidewall. Radials do not like to be ran on the sidewall. Plus another discover i made. RUN RADIAL TUBES in radial tires. This helps keep the tire cooler and they wont spin the tubes in the wheels
