Bent bar cars are probably the poorest choice as a starting point, but if that is what you want to use then give the guys at Firm Feel a call. Dick Ross raced a bent bar car for a few years and he has the parts that you'll need to get it to corner.

If you're going to road race it then you'll need some big front brakes. My 13 inch Viper kit will bolt on to the FMJ knuckle or you can get a kit from Baer or DoctorDiff.
