The Öhlins AUS MU00S1 Road & Track kit is a complete coilover package for the B9-generation Audi A4, S4, A5, S5, RS4 and RS5, built on Öhlins' Dual Flow Valve (DFV) monotube damper design. The kit is height adjustable and rebuildable, and it carries a two-year limited warranty. It uses an upside-down McPherson strut layout. Buyers choosing this over a budget coilover are paying for serviceability and a damper that can be rebuilt instead of replaced, plus a valve design meant to soften small-bump harshness while still controlling body roll on fast corners.
Spring rates are 120 N/mm front and 140 N/mm rear, which suits a street-biased track setup. Fitment spans the B9 chassis, but year coverage varies between sources, so confirm your model year before ordering. Keyword searchers looking for Audi B9 A4 DFV coilovers, B9 RS5 adjustable ride height coilovers, or 120 N/mm and 140 N/mm track springs will find the key specs below. Lowering amounts also differ between sources, so check the mounting instruction for your car.
Yes. The manufacturer describes the kit as fully rebuildable, so the dampers can be serviced rather than replaced when worn.
The manufacturer specifies that this kit is designed for use with the original top mounts.
Lowering figures differ between published sources. Follow the ride height guidance in the manufacturer's mounting instruction and confirm the expected range with the manufacturer before installation.
The kit includes a C-spanner for spring preload adjustment, along with owners' manual and mounting instructions, so follow the manufacturer's procedure for ride height setup and reusing the original top mounts. Before ordering, confirm with the manufacturer whether your car's factory adaptive or electronic damping system requires a cancellation kit to prevent suspension warning lights. Check the spring rate and spring supply details with the manufacturer, since sources differ on whether springs are included. Plan for a corner-by-corner alignment after installation.
