Front Left Control Arm, Lemforder - E46 non-M, Z4, Z4M

This is the OEM E46 ZHP control arm, made by Lemforder, the original supplier to BMW for the ZHP control arms and then used on the Z4M Coupe/Roadster.

With control arms, the quality of the ball joints is key to performance. Standard control arms use a ball joint with a plastic or rubber inner liner. Over time the liner wears out and leaves a lot of slop in the joint. The ZHP control arms, also called E46 Sport arms, have an all metal ball joint with much less slop and play even as it wears. This gives a much more direct feel in the steering and handling. With a better connection between the tire and the suspension, the steering feels better and the car feels more planted. They also last longer, especially when used in track and race cars.

The Genuine BMW ZHP control arm is also available.

This is an OEM ZHP control arm manufactured by Lemforder - the original supplier to BMW for this part, as well as many other arms and bushings. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
