E36 Subframe Issues
SuperPro polyurethane subframe bushings replace the factory installed rear subframe bushings that degrade over time and severely inhibit the cornering performance of your 3 Series BMW or M3 as the soft rubber breaks down. Old bushings not only impact your handling they also risk expensive frame damage by allowing your rear subframe to move and exert leverage on the long subframe mounting bolts until cracks form in your chassis. BMW addressed the issue by adding reinforcements for the 1996 production M3s to counteract the concerns for chassis cracks forming when rubber subframe bushings break down and allow the subframe to shift. E36s M3s built before 1996 and all E36 3 series owners will want to inspect your car to determine if upgrading your subframe bushings is sufficient or additional chassis repairs and reinforcement are required.
Stronger is Safer
SuperPro developed a solution for this issue with their polyurethane subframe mount bushings that offer superior strength and durability over the OEM rubber bushings. This increased strength properly locates the rear subframe to prevent shifting that can damage your chassis as well as create unpredictable handling. SuperPro's polyurethane was developed to have the material durability to deliver long term service in your BMW. The strength of polyurethane not only protects your chassis from damage, the reduced movement lessens wheel hop and maintains your alignment settings for better handling.
Rubber = Repetitive Repair
Rubber bushings are good for comfort but that comfort is short lived when automotive chemicals, heat, age, and impacts all break down rubber. Deteriorated rubber bushings allow your subframe and suspension components to shift around, negatively impacting ride comfort and cornering, and over time will damage your chassis and suspension. Avoid future replacements and the risk to your chassis that comes with rubber bushings by protecting your entire subframe with the strength of polyurethane subframe bushings using SuperPro's Rear Rearward bushing set.
Strength and Performance
Stronger subframe bushings are better able to tie your suspension components and chassis together to protect the subframe mounts as well as enhance cornering and handling of your vehicle. If your chassis requires repair or reinforcement, turn lemons into lemonade and create a lasting repair when you choose polyurethane bushings that will not only improve durability but cornering as well. SuperPro polyurethane bushings bridge the performance offered by solid mounted subframes with the vibration dampening and comfort of rubber bushings to deliver the ultimate driving experience for your BMW.
