Bill,
Thanks for the quick response! Sounds like this isn't your first rodeo. We appreciate all your knowledge and thanks for sharing!
Im happy to see someone build a proper suspension to harness the N54.
I have a question about LSD. If you switch to an M3 LSD would you also have to change to a 1M program? Forgive me if I'm wrong but doesn't the e89 have a computer controlled diff, while the M diff is mechanical? Would the ecu need to be modded to keep the system, engine power delivery and traction, in harmony? I worry the stock program and mechanical diff would fight each other with the computer cutting power. This is all speculation by the way.
I think your suspension set up, with fmic, upgraded oil cooler, ecu tune, and LSD would make for an incredible self made Z4M.
Thanks again!
Jake
