The rear lower control arms on E82/E9X models are the weakest link in the rear suspension. The arm is made from folded sheetmetal and it bends and deforms easily. Not only will it deform from potholes and curbs, tow truck drivers love to hook onto them without realizing how weak they are. We have seen other race teams complete the box section to make them stronger. A bent arm will throw off the geometry in the suspension, potentially affecting handling and tire wear. These aluminum arms are both lighter and stronger than the factory sheetmetal arms and is the best solution for chronic bending of the stock arm. These are a direct replacement to your stock arms with no changes needed to your alignment. New high-grade hardware is included.

Note: the stock arm is designed from the factory to be intentionally weak. These arms will bend so that something else in the suspension does not break. Our race cars used the stock sheetmetal arm but we replaced them often. We found that it was better to finish a race with a bent arm than not finish due to a catastrophic failure. The ECS arms are still designed to be the weakest link but are far stronger than the factory arm and will not bend as easily.

ECS Polyurethane Subframe bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Featuring 95A durometer polyurethane, ECS Polyurethane Subframe bushings are 25% stiffer than street bushings. Engineered to perform, ECS Polyurethane Subframe bushings offer a supreme level of control, while still maintaining enough comfort for the street. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure.

Key Benefits:

95A Polyurethane isolator reduces unwanted drivetrain movement while still allowing for an aggressive yet streetable driving experience.

Polyurethane bushings reduce subframe bushing deflection versus stock rubber bushings while keeping vibrations associated with such modification to a minimum.

Poly formulation and durometer, profile, and loaded surface area designed to minimize stress concentrations to stay within acceptable compressive strain limits of the material

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) ECS Polyurethane Subframe bushings were engineered to provide a balance of control while making ride quality more responsive, yet still streetable. As a factory bushings age, they become brittle and begin to harden and crack. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.
