seriously, leave it all alone. you could ditch the spare, seats, carpet, trim panels, hood swap, dash
and prolly only gain MAYBE 0.15 in a quarter mile. and the car would look like shit. you could prolly gain 0.5 just by learning different shifting techniques. i'm not trying to rip on you, it's just most people don't know how to properly get the best time via shifting in a quater.
