My question is, does this final drive (3,15) work better for you. I also have a heavily modded car pushing over 400WHP so this will help determine the final drive

I have the M3 rear on my FBO 135i and I am also 6AT. Going taller than stock sounds silly to me. I have the 3.85 of the manual M3 and it is perfect.
