BMW Control Arm Replacements & Upgrades for BMW E30 M3 S14 2.3L

Trailing arm bushings play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported 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 inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers. 

Looking to upgrade your front suspension to increase the strength and your steering angle for the track? IRP has you covered with their BMW Lock Kit. This kit includes new control arms that are stronger than stock, are a chromolon tubular system, and have monoball ball joints, new tie rod ends that feature steel monoball ball joints as well, new offset control arm bushings, fully adjustable camber plates, roll center/bump steer correction plates, and all new hardware. This enables this kit to be fully plug and play, giving you a much more adjustable front suspension, and increases the total amount of steering angle up to 70 degrees.

This kit is perfect for those looking to build a drift car and ensure their suspension is ready to take on the challenge.

*This Pro kit offers reduced weight control arms that help this kit shed 2.9 lbs from the standard kit while still remaining just as strong thanks to their chromolon tubular design.*

Kit features:

• CNC Laser Cut Components
