Turner Dual-Mount Differential Plate - F8X M2 M3 M4

Putting down big horsepower or putting down hotlaps in an M2, M3, or M4 may result in differential bushing failure. Even street-driven, 100% stock cars without increased horsepower see failures in as little as 30,000 miles.  Early cars (prior to 07/2018) utilize a hydraulic bushing that is prone to cracking, with a subsequent loss of internal fluid. This fluid loss renders the bushing useless, functionally allowing excessive slop in the differential mounting, which is felt as a clunk on throttle application, and possibly as increased noise and vibration while cruising. While no bushing is totally failure-proof (with possibly the exception of solid mounts, which are not appropriate for street use) stepping up to the Turner Motorsport Dual-Mount solution allows the use of a second rear-position differential bushing, which evenly distributes loading forces across two bushings - as opposed to one in factory configuration. Avoiding bushing failure is an important benefit, however in reducin
