Black Market Race Rear Differential Solid Mount Brace BMW B58 (G2x/G42) & Toyota Supra

The Black Market Race Rear Differential Solid Mount Kit is a supplemental brace that connects the rear differential cover directly to the subframe, significantly reducing flex and stabilizing the drivetrain under load. This added reinforcement improves traction and throttle response and reduces wheel hop, without replacing the factory mounts.

- Stainless mounting hardware; precision drill bit included
- Designed and manufactured in-house
