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

The B7 RS4 Avant puts a 4.2-litre V8 ahead of the front axle and carries an estate body’s extra mass over the rear, so a straight-line launch off the line has to fight a weight distribution that a saloon-bodied car doesn’t. XYZ Racing’s Drag Racing coilover is built specifically for that moment – not for a mid-corner load case but for the half-second where the quattro system decides how much grip each end actually gets.

For 0-400m runs on FWD, RWD or 4WD platforms, the kit lets you shift static weight bias toward the driven wheels at setup, rather than relying on chassis roll alone. On a Torsen-split quattro car like the B7, that means dialling more preload onto the rear to help the RS4’s factory rear-biased torque split actually plant power instead of spinning it away in the first fifty metres.

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

Set up correctly, the coilover forces greater compression into the drive tyres at launch, which shortens the window where a wheel is spinning faster than the car is moving. On a heavy Avant that’s the difference between the V8’s torque going into forward motion and it going into wheelspin and heat. Owners also notice the car holding its line better once the initial launch phase is over, because the weight transfer that got the car off the line doesn’t leave the rear unsettled once you’re into third and fourth gear. Because front and rear can be set independently, you can keep enough front-end control for the road-legal drive to and from the strip without giving up any of the launch bias when it counts.

About the Drag Racing coilover

XYZ Racing’s Drag Racing coilover is a dedicated 0-400m design, engineered around a single job: get the drive wheels loaded and gripping in the shortest possible time. The adjustable setup changes how the car’s front and rear weight is apportioned in an instant during hard acceleration, forcing more compression into whichever tyre is doing the driving. That reduces the idle period where a wheel spins without translating into forward motion, and it’s the reason a properly set-up car pulls harder off the line and stays more stable as speed builds. It isn’t a road-comfort product or a track-day coilover with drag settings bolted on – the geometry and adjustment range are built around straight-line launch behaviour, whether the car underneath it is front-, rear- or all-wheel drive.

Fitment for the Audi RS4 B7 AVANT 4WD (2006-2008)

This kit is built for the Audi RS4 B7 Avant, chassis AU20-1, across the 2006 to 2008 model years, and is matched to the quattro 4WD drivetrain fitted throughout that run. Confirm your car sits within this year range before ordering, as the B7-generation running gear changed at the model’s replacement.
