go for the stage 3. i had mine all of last season. i road raced twice, auto-x six times and went to the track about 15 times with 7 plus runs each time. 420hp/405tq the car ran an 11.8 which will be plenty of power for the street. i think your engine and trans will handle the power you will not run the car as hard as i did mine
