Adjustable rear control arm upper and lower set (4 adjustable arms) for the MINI Cooper and Mini Cooper 'S' results in improved handling and quicker turn-in response. These solid Heim joint control arms are a must-have for serious performance driving for track days and autocross competition. The solid Heim joints eliminate any play induced by the stock rubber or poly bushings - this means precise suspension geometry is maintained during transisions for maximum control!

This Rear Control Arm Set consists of four (4) weld-free adjustable control arms, pre-assembled with high quality oversize heim joints and threaded for quick and accurate full adjustment of rear toe and camber. Weldless construction includes flat wrench notch for easy adjustability.
Our four adjustable arms achieve precise and independent adjustment of toe-in and camber - unachievable with two arm kits. Think of a 'triangle' - with the 4 arm kits, you change two legs of the triangle, with the 2 arm kits, you only change one leg of the triangle. This means both camber and toe-in are affected simultaneously with the 2 arm kits - not the best solution!
'Toe-in' means the front edges of the two rear or front tires are angled inward toward each other, with 'toe out' being the inverse. While severe amounts of incorrect toe and/or camber will result in unwanted tire wear, a small amount of toe change in the rear can make the car turn-in more predicatable. 'Camber' is the amount of tilt the tire has top to bottom. Negative camber, with the tire tops angled inward relative to the bottom, will increase the cornering ability.
The lack of rubber bushing makes these control arms very precise. However, the solid Heim Joint (Pillow Ball Rod End) may generate some knocking noises as the arm rotates when going over bumps on the street. This is 'normal' for this product.
On MINIs with the optional Xenon Headlights - there is a 'level sensor' used by the Xenon Headlights that attaches to the Drivers side Upper Rear Control Arm - these Adjustable Control Arms do not have accommodations for attaching this sensor. Most customers simply us a couple of standard 'hose clamps' to affix the sensor to this arm.
