The stock rear upper control arms on your BMW weren't designed for the Track. This becomes apparent when deformation begins to occur to the sheet metal construction of the control arms and the rubber bushings begin to fail.
To remedy this, Turner Motorsport now offers its very own upgraded rear upper control arms with FK rod end bearings. These control arms are significantly more stout, holding up to the forces experienced on the track, without flexing or bending like the stock control arms. This helps to improve overall handling and stability with only a slight increase in expected NVH.
