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

i agree this is a great site. has some good info . everything sounds good except the air presure. try this lf 9 psi rf 13 psi rr 13 psi lr 11 psi if you cant run beadlocks go up 2 psi on each tire. as far as offsets go with 2 inch offsets every where when the track is wet, if it goes tacky put a 3 inch offset on the rr, if it goes dry slick put a 4 inch off set on the rr. and get some good shocks. bilistein shocks are what i have been running on my street stock. it is a big monte carlo but i ran a small monte carlo last year and won 4 races and got several seconds in about 12 races. every one likes a little different set up so start here and figure out what you like and feel comfortable with. good luck. c17 charlie norris

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??

on a street tire i always run tubes and never run below 18# with a tube and a bead lock you might be able to go a little lower on that corner but not much

last year i ran 255/70/15 on a pure stock with the above presures and had no problems w/wo tubes what you have to do is when you mount the tire air it up to 20 psi after the bead seats and let it all the way back down so the tube is not stretched and then air it up to 35 psi and set it out in the sun all day and then put it on the car and when it is race time let it down to the above psi. i now run street stock and run bead locks on the r/r with 10 to 13 psi depending on track condition. if you feel uncomfortable with these just run what you think is right for you. you will get different set up tips from different people that may or may not work , just find a happy medium and the longer you run and experiment the more you will learn. ask around at your track from the people that are doing well and watch and learn from them. most will be happy to help. charlie norris street stock c17 bellmead speedway. bellmead tx.

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
