well i run an old set of mickey thompsons tubeless tires. they are 18" wide and i have to use a 10" wide weld racing rim. i bought them from a garage sale for 75 bucks, the chassis is rusty. but i put a set of shocks on the front that my stepdad said would lift the front end off the ground. i have a set of 4:10 gears in the rearend and that helps too but the car is now gone and all i have left is the motor until i find a better car. i was told that an oldschool ferrari or porshe is a full frame car that can handle up to 1000 hp without anything like a stablizer or anything to help support the frame i dont know for sure but that is what i heard.
