The Megan Racing Front Lower Control Arms for Golf 5/6 and Audi A3 are a complete replacement of the factory component. Using a molded design similar to the factory arm, but with polyurethane bushings installed, allows for better cornering response. A slight geometry change of -0.3 Camber/+2.5 Caster will also help improve the vehicle's cornering contact patch and steering memory. A must-have upgrade for those looking to get the most out of their vehicle's cornering performance. Megan Racing control arms are constructed from lightweight cast aluminum that is able to withstand the stresses of extreme competition while keeping weight to a minimum. Polyurethane bushings provide unrestricted freedom of movement while eliminating any slop unlike factory molded rubber bushings which will not only increase the vehicle's dynamic response but also allow the suspension to absorb more road forces. All hardware is treated to help prevent corrosion in the harshest weather conditions and is protected by a one-year warranty against manufacturing defects.
