how fast do you want to go?ive been mid 9s on a 275/60DR in a stock wheelwell offset shackle SS spring dart.ive ran a 29x9goodyear slick also but i believe thats about the limit.i wouldnt bother cutting the car up if you dont plan on going very quick.i just went to minitub/caltrac deal 325/50DR and have only been .007 faster and somewhat regret doing it.if it wasnt for hit im going to put down it next season i would have left it stock.
