When high torque loads and aggressive corner exits push your chassis to the limit, stock differential mounts quickly become the weak link. The ECS Tuning Rear Differential Front Mount Upgrade Kit is track-engineered to lock down your rear diff, control axle wrap, and ensure immediate power delivery to the pavement.
Built to withstand severe track abuse, this kit eliminates hardware failure by replacing the undersized factory M12 bolt with an ultra-high-tensile Grade 12.9 M14x1.5 bolt. Surrounding the upgraded hardware is a track-spec 95A durometer red polyurethane bushing and a rugged 6061-T6 aluminum sleeve finished in Type II black anodizing. Engineered for maximum drivetrain stiffness, this upgrade ensures your differential stays precisely aligned under the harshest motorsport conditions.
The Powerflex Front Lower Control Arm Rear Bushing - Aluminum Shell (Centered) for BMW E30, E36, Z3, and Z1 is a premium upgrade that enhances the performance and longevity of your vehicle's suspension system. This bushing replaces the factory rubber component with a robust polyurethane bushing encased in an aluminum shell.
This Powerflex Front Lower Control Arm Rear Bushing is an excellent choice for enthusiasts looking to improve their BMW's handling and durability while maintaining comfort for daily driving.
