mk3 supra NA vs. Mitsubishi 3000GT NA

[Supra2NR]

you can remove your spare tire, and the other stuff in your trunk,
take the backseat off too

i dunt know about taking the targa off, cuz i believe that gonna create drag and wind resistance, which will make him slower than when he had it on

i wouldnt take off the aircleaner, why?
because why would want unfiltered air to get your engine?
in the long run those things can ruin your internals
plus is it really worth it for this race?
how much money are you gonna make if you win?

and jus keep the tires at normal pressure, over-inflating your tires will reduce your contact patch which will in term you'll loose grip, and traction
and it can make your ride bumpy in a race, remember you want your car to stay connected to the road as much as it can

and its not really manual shifting the auto its jus launching it
put it in the lowest gear possible , when you launch it have it redline then put it back to "D", then punch that pedal , and hope for the best
