XYZ Racing Super Sport Coilovers — Audi RS4 B7 AVANT 4WD 2006-2008

The B7 RS4 Avant carries a 4.2-litre V8 over the front axle and puts drive through all four corners, a combination that loads the nose hard under braking and asks a lot of the front dampers when you turn in off that braking. Standard-issue suspension on this generation was tuned for ride comfort first, which leaves the chassis feeling soft exactly when the Avant’s extra weight over the rear wants managing.

The Super Sport coilover is built for exactly this kind of fast-road and weekend track use, where the car needs to shed the factory wallow without turning into something unliveable on the school run. It replaces the front and rear damper units on the AU20-1 chassis with a setup you can adjust for both height and firmness, rather than accepting whatever compromise Audi signed off for a global market.

What this coilover does for your 2006-2008 Audi RS4 B7 Avant

Lowering the ride height on the Super Sport kit pulls the RS4’s centre of gravity down, which matters more on the Avant than the saloon given the extra mass sitting behind the rear axle. That, combined with 36 levels of damping adjustment, lets you firm up the front end enough to control the V8’s weight under trail-braking into a corner, then back the rear off again for a daily commute where the Avant needs to soak up B-road surfaces rather than jar over them. Because the quattro drivetrain is putting power down through all four wheels rather than two, a damper that keeps the car settled mid-corner pays off in traction out of the exit, not just in outright grip. Independent ride-height adjustment also means you can correct the nose-heavy stance the B7 picks up once a full tank and passengers go in, without touching spring rate.

About the Super Sport coilover

The Super Sport design targets the discomfort that comes with a stiff coilover on rough UK B-roads – the kind of setup that transforms a car on a smooth circuit and then beats up the driver on the way home. Height adjustment is built into the damper body so the RS4 can be set low for a track day and lifted back for everyday clearance without swapping parts. The 36-way damping adjustment gives a genuinely wide spread between a supple road setting and a firm track setting, rather than a handful of clicks either side of one compromise valve. XYZ Racing positions this as a damper for both weekend competitive use and daily driving, which fits a car like the RS4 Avant that most owners still use to get to work through the week. The construction is built to handle the recurring load of repeated adjustment rather than a single set-and-forget install.

Fitment for the Audi RS4 B7 Avant (2006-2008)

This kit is built specifically for the AU20-1 chassis code – the B7-generation RS4 Avant estate with quattro four-wheel drive, sold in the UK across the 2006 to 2008 model years. Confirm your car matches this chassis code and body style before ordering, as B7-generation Audis span multiple drivetrain and body configurations that use different mounting points.
