BMW Suspension Parts

Take total control of your E36's handling with the ECS Performance 2-Way Adjustable Coilover System. Built specifically for track use, this system bridges the gap between standard off-the-shelf coilovers and full-fledged motorsport suspension. These coilovers feature independent compression and rebound controls supported by external reservoirs; unlocking the precision tuning needed to shave seconds off your lap times.

Traditional 1-way coilovers force a single adjustment knob to balance both bump and rebound. These 2-way dampers eliminate that trade-off with fully independent compression and rebound controls. Use the 32 levels of compression adjustment to control front weight transfer under heavy braking, maximizing entry grip and allowing you to trail-brake deep into corners without understeer. 22 rebound levels fine-tune chassis recovery on brake release, keeping the front tires loaded through the apex for faster power-on exit speeds.

To maintain consistent performance during extended periods of performance driving, these dampers feature dedicated external fluid reservoirs that significantly increase total gas volume. During rigorous track use, rapid piston movement generates intense friction and heat, causing standard damper oil to thin out, aerate, and lose its damping force. By increasing overall fluid capacity, the external reservoirs effectively dissipate heat to keep peak oil temperatures down.

Enhance rear-end control and put more power to the ground with a straightforward 3-piece design that installs with ease. The factory rubber may favor ride comfort, but it struggles to keep up when driving gets aggressive. As it wears, the OEM bushing can soften and deform, reducing stability and allowing wheel hop to creep in when you need traction most.

Our 95A durometer polyurethane bushings solve that problem. Engineered to strike the perfect balance between soft factory rubber and harsh solid mounts, they significantly reduce differential movement without introducing excessive vibration. The result is more efficient power transfer, so your torque goes straight to the rear wheels instead of being lost in drivetrain flex.

Features & Benefits:

Minimizes differential movement and instability to help eliminate wheel hop
Two-piece 95A split polyurethane design for easier installation
Precision-fit insert reinforces the bushing and strengthens mounting points
Resistant to road salt, oils, and harsh chemicals
Compatible with dual mount differential plates
Design:

Type II Anodized 6061-T6 CNC billet aluminum inserts for superior corrosion resistance and durability.
95A Polyurethane 2-Piece Isolator.
Product Development:

Our Rear Differential Bushings are designed, engineered, tested, and quality inspected by our Research & Development team. Our development process includes leading-edge product technology: FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

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.
