XYZ Racing Super Sport Coilovers — Audi S4 B7 4WD 2004-2008

The B7 S4’s naturally aspirated 4.2-litre V8 sits well forward of the front axle, and quattro’s permanent four-wheel drive means that weight is always working against the front tyres under trail braking and direction change. Factory suspension on this generation was tuned for motorway comfort first, leaving the chassis softer than the drivetrain deserves once you start using the car the way it was clearly built to be used.

XYZ Racing’s Super Sport kit is the fast-road and weekend track-day answer to that mismatch. It replaces the compliance-biased factory dampers with a coilover platform built to control that nose-heavy mass properly, without turning the B7 into something you dread driving to the circuit.

What this coilover does for your 2004-2008 Audi S4 B7 4WD

Ride height is fully adjustable, so you can drop the S4 to sharpen turn-in and cut the aero-relevant front overhang without dragging the front splitter on speed bumps. The 36-way damping adjustment lets you soften the compression stroke for a B-road blast one weekend and firm the rebound up for a trackday the next, which matters on a car this heavy through direction changes. Where the standard setup lets that V8 mass roll into a corner and load the outside front tyre unevenly, a stiffer, properly damped spring rate keeps contact patch loading more consistent, so the quattro system has a more settled platform to put power down out of slower corners.

About the Super Sport coilover

The Super Sport range was built to solve a specific complaint: factory-style dampers that transmit every bump and expansion joint straight into the cabin, without buying you anything in return through a corner. This kit keeps that ride quality intact over rough UK B-roads while adding proper adjustability on top. Ride height adjusts independently of damping, and the 36-way damper gives a wide enough spread to move from a comfortable daily setting to a firmer, track-day-focused one on the same set of dampers. It’s built as a dual-purpose unit rather than a dedicated race piece, aimed squarely at owners who want one coilover kit that covers both the commute and the odd trackday without swapping parts.
