If you go the the drag strip to race should you take your full spare tire out of the trunk?

Question

2003 mustang gt - so rear wheel drive. Would you leave the full spare in the truck or take it out before racing it in the 1/4 mile?

Answer 1

It depends on how badly you want that lower E.T.

It takes roughly 100lb weight savings to gain an extra tenth of a second in the 1/4 mile, so you'd have to take out alot more than the spare tire to see any significant gain.

Personally, I'd leave the spare tire and just work on things like reaction time and getting a good launch. Once you feel that you can drive the car to its potential, then you might want to look at trimming weight from the car.
