Improve front-end stability, steering response, and cornering control with the SuperPro SPF3397K control arm bushing kit. Designed for the front lower inner rearward control arm, this offset bushing kit adds positive caster to the suspension geometry of select Audi TT Quattro and Volkswagen R32 applications. The increased caster helps the vehicle track straighter, return to center with less driver input, and provide a more planted steering feel during everyday driving and spirited handling.
As steering angle increases, the added caster promotes dynamic camber gain, helping both front tires maintain more contact with the road as the suspension loads in a corner. This can improve cornering grip and help resist tire rollover onto the shoulder. The SuperPro SPF3397K delivers these handling benefits without compromising tire wear, ride comfort, or predictable road manners when properly installed on a compatible vehicle.
Manufactured in Australia using SuperPro's proprietary engineering-grade polyurethane, these bushings offer a durable alternative to conventional rubber components. The material is designed to withstand extreme temperatures, oils, water, and coolant while maintaining effective noise and harshness isolation. With nearly five decades of suspension development behind its designs, SuperPro combines long-term durability with refined performance for street and performance applications. This kit is backed by SuperPro's limited lifetime warranty and fits select 2000–2006 Audi TT Quattro models and the 2004 Volkswagen R32. Verify vehicle application before installation.
