Hi all,
I stumbled across this MFactory helical HSD for the non-M Z4's: http://www.teammfactory.com/catalog/partno/MF-TRS-05E46A. Has anyone had experience with installing this, or any LSD retrofit in general? Any noticeable improvements? Curious especially for track use / getting traction while coming out of a corner.
