Risks of Speed
SuperPro polyurethane subframe bushings have the necessary strength and durability to handle grippier tires or a sport suspension that can exceed the design capabilities for your car and expose a weakness such as the rear subframe found on the 1992-1999 E36 chassis BMW. Increasing your car's cornering ability in the pursuit of speed can be very rewarding but can pose additional problems for your BMW. Too much movement of the E36 rear subframe risks damage to the chassis mounting points that requires costly repair to avoid unsafe operation. Drivers pushing the limits aren't the only source of excessive subframe movement, old rubber bushings are also unable to properly locate your subframe and need to be replaced before they create a cascade of failure as suspension components shift.
Material Strength
SuperPro polyurethane subframe bushings use a material with superior properties over the factory rubber bushings for longer lasting performance and protection for your BMW. Rubber's susceptibility to oils, heat, and even age will break the factory bushings down to destroy the comfort and protection they provide for your suspension and chassis. SuperPro's engineers have leveraged the strength of polyurethane to create subframe bushings that protect your chassis from damage by resisting deflection and deterioration from environmental hazards.
Better Than Factory
Exceed the performance potential your car possessed when it rolled off the factory line when you replace soft rubber bushings with durable polyurethane subframe bushings that are better able to support the rigors of spirited driving. Not only does subframe movement risk damage to your chassis it damages the handling of your vehicle by allowing suspension components to move and shift around unpredictably. Restore predictable handling to your BMW with bushings that offer the strength to precisely locate your rear subframe during standard driving and when you decide to test the limits of your capabilities.
Improve, Augment, and Upgrade
Suspension parts that augment the already amazing handling of your 3 series or M3, such as shocks and springs or sport tires, are very popular. Polyurethane subframe bushings create a firm foundation that is extremely beneficial for utilizing the full potential these suspension upgrades provide for your BMW. Bushings that resist deflection create a better connection to the road for the driver that can be best described as a more crisp steering feel. Install SuperPro's full complement of polyurethane subframe bushings using their Rear Forward bushing set to experience how much better your time spent behind the wheel of your BMW can be improved.
