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.
Designed to work with the original bushing and eliminate over compliance or better known in motorsport as 'lost motion' of the rear crossmember. This Whiteline kit dramatically reduces rear cross member misalignment and movement which allows a more positive feel from the rear end during cornering.

These bushings have the hole off-center to give your car a little more track, caster, and camber. This style came as standard equipment on E30 M3s (8/89-later) and 1995 E36 M3 but will work with any E30, E36, Z3.
Rubber control arm bushings are designed to flex and absorb energy. That's fine on a streetcar but on an all-out racing machine you want your alignment to stay constant. We have picked Delrin for this application due to its high rigidity and low coefficient of friction allowing for minimal suspension bushing deflection (geometry change) but decreasing bushing windup or drag (friction). They are not recommended for street-use but highly-recommended for track cars.
To save time, pick up a pair of new bushing carrier brackets and hardware. This will save you the time and hassle of pressing out the old bushings. This will especially save you time if you're buying new control arms at the same time (no time wasted removing the old brackets from the arms). Stainless steel set screws included.

These bushings replace the stock rubber bushings and offer a better driving feel, increased lifespan, and better wheel alignment.
Rubber bushing allow for a lot more movement and are more susceptible to wear and tear from spirited driving and harsh weather conditions. Polyurethane is much more resistant to wear and is stiffer, reducing the total amount of movement that would normally affect the alignment negatively.
