Racingline front alloy control arm with bushes.
The MacPherson strut front suspension layouton the VWG ‘A5’ platform cars (such as Golf 5, 6, Scirocco, A3, S3, Leon, Octavia) is a common design. Although it is a popular choice for manufacturers, due to its simplicity and low manufacturing cost, the standard design has a few disadvantageswhen it comes to high-performance applications.
Firstly, there is almost zero freedomto adjust staticcamber, caster orroll-center geometry which is absolutely critical for handling on the VWG A5-platform cars.
The otherdrawback for high-performance use is that as this layouttends to transmit noise and vibration from the road directly into the body shell, manufacturers have to add extra noise reduction and isolation mechanisms. In other words, plenty of movement in the original factory soft rubber bushing controlling the lower control arm.
Products intended for vehicle modification for competition purposes may render their use prohibited on public roads, insofar as they significantly alter the vehicle's characteristics as specified in the type-approval certificate issued by the relevant authorities (noise level, pollutant emissions, maximum speed, tire dimensions, etc.).
