what i'm doing w/ my car is building the engine and keeping the drivetrain stock cept for a manual valve housing and when something breaks cause of 2much hp replace it with the best part available at the time that way you don't have to spend all of your money at once and replace parts that will handle the stress for another year when you don't need to as for me i've got 2 sets of tires one 7inch wide and one 4.5inches wide the 7 inchers are for when i go to shows and race the 4.5 are for driving on the street
