ZPOST - View Single Post - Change Z4 3.0Si Diff to M LSD

Incompatible · 12-23-2008, 02:13 PM

I'm doing my research for options on upgrading my non-LSD diff to a limited slip type for my 2007 3.0Si Coupe. Performance, cost, and maintenance are the main aspects of interest. Car use is primarily for street but will see some autox and track time.

I've looked at the Quaife and Performance Gearing setups and would like to compare those to the Z4M setup. I realize that the M swap would require additional subframe parts, not sure which. I've read through most of the threads on this topic, but price info is minimal.

Any info / thoughts are appreciated.
