+1 for AMSoil - the absolute best syn fluid on the planet. Change your tranny fluid too. 3.5 qts for tranny and 1.6 or so for rear end.

all AMSoil diff fluids already have the friction modifiers in them, just go buy severe gear 75w90 for the diff

after you do this your car will feel like you put a new tranny in, seriously, I have an 04 6MT coupe with 50k on it, made a huge difference
