Alright, just doing some basic maintainence.. need to know the fluid type/weight required for the rear end, and capacity. also the same goes for the transmission. i will be using royal purple products, has anyone used synchromax in the transmission of an M3? i use it in my 500+hp camaro with no problems at all. all opinions welcomed!

syncromax for the tranny, and max gear oil 75/90 I believe. 2 Quarts a piece.

yup, i would use either red line, royal purple, or amsoil. for the tranny, you can use either auto or manual tranny fluid, i've heard so many different opinions on what to use its really up to you. for the diff, use 75w90. and yes, about 2 qts a piece

redline D4 ATF for the trans, works well for me.
