While the Quattro all-wheel-drive system provides phenomenal grip, the factory suspension setup on the S4 and S5 can exhibit noticeable body roll. Upgrading your handling hardware transforms your B9 into a precision cornering weapon.
Coilovers & Springs: Close the arch gap and lower your centre of gravity with lowering springs or height adjustable springs, or achieve ultimate damping with fully adjustable coilover kits. Upgrade your stock setup with a set of new shock absorbers.
Chassis Bracing & Control: Eradicate flex and dial in your alignment with uprated anti-roll bars, suspension braces, and adjustable control arms. Lock down your geometry using stiffened polyurethane suspension bushes.
Supporting Hardware: Correcting geometry after lowering is vital. We supply uprated drop links to eliminate anti-roll bar pre-load, alongside a wide selection of misc suspension parts.
