Replacement upgrade & correction bushes for MK5 and MK6 VAG models
Over recent years it has become apparent that the standard rubber bushes fitted at the rear of the front control arms on VAG models that are based on VW Polo 9N, Golf MkV and Golf MkVI chassis’, quickly become weak and start to deteriorate. This is due to the bush being mounted vertically and, as the suspension moves up and down, the rubber is designed to twist.
This problem can be directly linked to the vertical mounting of the bush. Any movement in the car’s suspension is achieved through the rubber distorting, which in time will result in the rubber starting to tear, allowing forward, backward and sideways movement of the control arm. This results in vague handling, steering-pull and uneven tyre-wear. The fitting of SuperPro bushes not only eradicates these issues, but can also fix alignment problems that are caused by worn original components settling in an incorrect position.
SuperPro’s replacement polyurethane bush features an innovative two-piece design that in practice works as a free-pivoting bearing: locating positively enough to keep the arm in its rightful position, but flexible enough to absorb the shocks and vibration that would make a solid joint impractical. This configuration allows the control arm to move up and down freely, whilst eliminating the forwards, backwards and side-to-side travel. Consequently, the car has a more precise feel and steering response is improved, whilst ensuring the suspension maintains its alignment.
The polyurethane construction of SuperPro’s bushes enables the use of an offset or eccentric centre. This allows the pivot-point of the bush to be re-positioned and allows the caster angle to be adjusted. The diagram below shows the options available.
By using an offset bush on one side of the car and a standard SuperPro bush on the other, caster can be altered to accurately correct steering pull. And, by using an offset bush on both sides of the car, this will see improvements in straight-line stability and or reduced ‘lift’ under acceleration.
