MQB platform cars use a stamped steel rear upper control arm to control rear camber.
The adjustable rear links are a direct replacement for the stock stamped steel and soft-ring arms, and allow for plus or minus 3 degrees of camber adjustment, in addition to what the stock eccentric bolt allows.
High-durometer rubber bushings on each end ensure minimal flex under the extreme loads of track use. But without the hardness of a solid ball joint, which is not suitable for regular road use.
The "Twin-thread" design offers clever stainless steel adjustment on the left and right for infinitely precise camber adjustments on the car. Most other arms only adjust 180 degrees, requiring disassembly and reassembly between adjustments.
