Put more power or sticky tires through it and that differential moves, which shows up as slack on and off the throttle and, over time, seeping differential and CV seals. The \u003ca href=\"\/collections\/mmr-performance\"\u003eMMX Performance\u003c\/a\u003e 4-Point Differential Lift Kit locates the differential at four points instead of three, so it stays planted under load.\u003c\/p\u003e\n\u003cp\u003eThe fourth point is the key. MMX's dual differential mount uses a secondary bushing location BMW leaves empty, giving the differential a new rear support structure. The whole system installs at factory height or raised +10mm, so it works on a stock-height car and corrects driveshaft geometry on a lowered one.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow the 4-Point Differential Lift Kit Works\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe \u003ca href=\"\/products\/mmx-performance-g8x-m2-m3-m4-rear-differential-front-cradle-mount-set\"\u003eMMX front differential cradle (MMR55-1604)\u003c\/a\u003e replaces the factory front mount and is machined from 6061-T6 billet aluminum.
