Our Audi S4 B9 Quattro coilovers are height-adjustable from 25mm to 75mm below stock height. They offer higher spring and damping rates over the stock suspension to improve your S4’s stability, grip, and look – all backed by the best, hassle-free lifetime warranty in the business and 30-day returns.

Please note that this kit requires the usage of your factory upper mounts. For some vehicles, installation of this coilover kit may require the use of wheel spacers to achieve proper wheel and tire clearance. Drop ranges are approximate. Actual drop range will depend on vehicle age, other modifications, and wheel/tire setup.
