Hardrace BMW 3 Series E46 Adjustable Rear Camber Arms with Rose Joint Bushes

Hardrace BMW 3 Series E46 Adjustable Rear Camber Arms with Rose Joint Bushes

The first benefit to fitting the Hardrace alignment arms is that they come with either an uprated bush or a rose joint. These uprated components minimise the movement in the arm in comparison to the standard items. You want minimal movement as any movement translates through to the steering in the form of vagueness and a lack of response the steering input. Each and every original bush has a degree of slop built into it to maximise the cars compliancy and minimise noise and vibration being passed into the cabin. This soft nature is exaggerated with age as the bush starts to deteriorate and their resistance to forces reduces leading to greater and greater deflection under load. As you turn the steering wheel the original bushes start to take the strain and in doing so compress. As they compress you have to compensate via the steering wheel as the original inputs effect is reduced via the bushes squashing.

You can improve the cars steering response and reaction to input by minimising or eliminating the play that exists in the original soft bushes. For the majority of road cars the Hardrace uprated rubber bushes will be sufficient. We use rubber rather than polyurethane due to the better noise and vibration absorption properties with no loss of effectiveness in reducing deflection in comparison to polyurethane. If you want to eliminate play completely then we offer rose jointed bushes. These provide a complete elimination in play for maximum response to steering input. Rubber and polyurethane bushes provide significant resistance to arm movement, they want the arm to sit in the position it was fitted in so when the wheel moves upwards through its travel the bush tries to push the arm back down to its resting position. The rose joints allow free movement of the arm with minimal stiction. This allows the suspension to work more efficiently improving the spring and dampers ability to function as designed and keep the cars tyres in contact with the ground and control body movement.

The majority of the Hardrace arms are adjustable. This allows you to alter key elements of the cars geometry to optimise the handling characteristics.
