Product Description

The Ohlins AUS MU00S1 is a Road & Track coilover suspension kit for the 2017-2023 Audi A4, A5, S4, S5, RS4, and RS5 on the B9 platform. The system features Ohlins' patented Dual Flow Valve (DFV) technology, which simultaneously controls low-speed and high-speed compression and rebound damping through a single adjuster per corner with 20-plus click settings. The front utilizes inverted McPherson struts with aluminum bodies for reduced unsprung weight and improved rigidity, while the rear features conventional shock absorbers with separate spring preload adjusters for independent ride height tuning. Front springs are rated at 120 N/mm and rear springs at 140 N/mm. At the recommended setup, the vehicle sits approximately 35mm lower than the factory ride height. Rebound damping is tunable from full-soft street comfort through winding road settings to firm track use. The kit reuses the factory OE top mounts on both front and rear, and includes two sizes of top pin spacers and upright spacers to accommodate different B9 model specifications. Vehicles equipped with OE electronic dampers will require the Ohlins EDC cancellation kit, part number 35020-31, sold separately -- this plug-and-play module deactivates dash warning lights and error codes with no programming required. Not compatible with vehicles equipped with magnetic ride control. Like all Ohlins Road & Track products, the AUS MU00S1 is fully rebuildable, has been corrosion tested to ISO 9227 standards, and is backed by a worldwide 2-year limited warranty.
