Control arms are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.

Engineered for durability and performance, these bushings provide improved handling and responsiveness. Specifically designed for BMW E8X and E9X models, they ensure a precise fit and reliable performance. Reduce vibrations and enhance driving comfort with these high-quality replacement bushings.
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.
Note: Upgrading to M14x1.5 hardware requires drilling and tapping the original M12x1.5 differential mounting hole. See T#58563042 for a complete kit that includes the proper-sized drill and tap.
