Track info Track types: 0 = short track 1 = mile oval 2 = medium oval (>1 <2) 3 = long oval (think this is the 2 mile) 4 = super speedway 5 = road course Chassis types: 0 = ? 1 = super speedway 2 = speedway 3 = short track 4 = road course Here are some things I found while testing at Talladega - Chassis 0 - high drag, huge torque, tires never wear out, top speed around 190. Chassis 1 - low drag, low HP, fixed rear springs, shocks and spoiler, top speed around 185. Chassis 2 - medium drag, top speed around 210. Chassis 3 - medium drag, top speed around 205. Chassis 4 - medium drag, top speed around 205. Chassis 5 - minimal drag, doesn't like to turn or stop, top speed around 240. You results may vary.
