Ever wonder how the Volkswagen Racing Cup cars find the front negative camber, additional caster and geometry control that is so vital on-track? It’s the ‘Cup Edition’ Front Suspension Upgrade Kit. BACKGROUND The MacPherson strut front suspension layout on 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 disadvantages when it comes to high-performance applications. Firstly, there is almost zero freedom to adjust static camber, caster or roll-center geometry – which as we know from our race programme is absolutely critical for handling on the VWG A5-platform cars. The other drawback for high-performance use is that as this layout tends 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. WHY UPGRADE? VWR Susp Banner race The ‘Cup Edition’ Front Suspension Upgrade Kit is a race-proven package of upgraded hardware and replacement motorsport-specification bushes developed exclusively with our Championship Technical Partners SuperPro for the R Performance Parts range. This is exactly the kit that our Cup Race Cars use, and will transform the handling and steering feedback on your car. It is the ideal companion kit to our Rear Suspension Bush upgrade (R54G5COMP) – we recommend uprating both front and rear suspension at the same time for best effect. Together, the fitment of the ‘Cup Edition’ Front Suspension Upgrade Kit will allow you to adjust in an additional 0.5 to 1 degree static negative camber to the front wheels via the slotted lower control arms, together with another degree of castor given by the offset front control arm rear bushes. Plus it provides a 44% unsprung weight-saving from the cast steel original arms. The Lower Ball Joints supplied with the kit have a longer pin which provides some roll-centre correction on a lowered car by lowering the angle of the lower arm back down to closer to optimum. The original soft factory rubber bushing allows the lower arms to move significantly in both the longitudinal and torsional axes in a high-performance environment. Whether over bumps, compressions, accelerating or braking this movement is highly undesirable for steering response and geometry control on track. The black, motor-sport specification polyurethane replacement bush materials ensure maximum geometry control and driver feedback, developed exclusively with our Technical Partners SuperPro to our own specifications. Very importantly compared with rubber bushes, the free pivoting design means that there is no spring rate resulting from material wind-up, helping optimise spring & damper settings. This is a particularly good upgrade for a car that has covered a higher mileage, as the original rubber bushes will have deteriorated significantly with age. This kit really brings back the ‘new car’ feel.
