New F97/F98 Bulletproof Differential Mount Kit

Put an end to drivetrain flex and destructive wheel hop. The S58 engine is an absolute torque monster, especially once you start tuning and turning up the boost. But while aggressive launches and heavy acceleration are the best part of owning these vehicles, the factory rear differential mounting wasn't built to handle that kind of abuse.

The OEM soft rubber bushing allows excessive differential twist and flex under load. This deflection transfers massive, uneven force directly to the factory mounting bolt, leading to bending or catastrophic snapping. The Turner Motorsport upgrade replaces that weak link, locking down your drivetrain to ensure every bit of horsepower safely makes it to the pavement.
