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.
