OK, so let me get this straight. You expect to build a supercharged 'stang and NOT drive it hard. Um-kay . . . me, I drive mine like it's a rental in Jackie Chan's name . . . clutches are cheap.
Beat that thing like it owes you money . . . your 'stang that is . . .
basically If I were you I would just start an upgrade fund.
with stock tires you only have so much traction so you can only apply x amount of torque before you spin. once you run a sticky tire at that power level you will just espose the weaknesses.
for example the t-45. there is nothing you can do other than replace it if you wanted to launch on slicks. It will let go eventually. replace it will a TKO and you can launch all day long. same goes for the axles, axle tubes, torque boxes. you can damage those at near stock power levels on slicks.
