The control arm comes complete with bushes and ball joint and are sourced directly from the manufacturer - the same manufacturer that make them for Porsche. There is one control arm per wheel on the vehicle and these are not "handed". The same control arm can be used to fit the front or rear suspension and also the left or right hand side of the car.
Contrary to popular belief, bush and ball joint kits are not available for these components from Porsche and Porsche recommend that the whole control arm is replaced when worn.
These control arms are sometimes called "wishbones" and are often reffered to in the trade as "coffin arms" due to their shape!
