XYZ Racing Street Advanced Coilovers — Audi S3 SEDAN 8V φ55 (Modified Rear Integrated) 2013-2020

The 8V S3 Sedan’s quattro system shuffles drive rearward once the Haldex clutch bites, but at rest and through initial turn-in the nose still carries the EA888 turbo four and a front differential few owners ever unload. That weight bias is what makes the standard suspension feel soft and slightly nose-led on a B-road, and it’s exactly what the Street Advanced coilover is built to correct without turning the car into a track weapon you don’t want to drive to work.

XYZ Racing positions Street Advanced as the road-first tier of its range, tuned for owners who want sharper body control on a spirited drive or the occasional track day, not a car set up purely for lap times. For a quattro saloon that spends most of its life on UK roads, that’s the right starting point.

What this coilover does for your 2013-2020 Audi S3 Sedan

Lowering and stiffening the spring rate front and rear tightens the S3’s body control through direction changes, reducing the amount the nose dives under trail braking before the quattro system redistributes torque. The damper’s 720-way adjustment range lets you set a firmer low-speed compression for motorway cruising and open it back up for broken B-road surfaces, rather than living with one compromise setting all year. Because the kit is height-adjustable, you can also correct the slightly high factory ride height that the 8V carries to clear its Haldex-driven rear axle, dropping the centre of gravity without resorting to spacers or altered geometry. On a car where power already outruns the standard chassis in the wet, that extra front-end composure through mid-corner load transfer is the difference you’ll feel first.

About the Street Advanced coilover

XYZ Racing describes Street Advanced as its most widely fitted line, refined over several development cycles and shaped in part by lessons from the brand’s motorsport programme rather than built purely on a test bench. The headline spec is a 720-position damping adjuster, giving a far finer gradation between comfort and control than a basic single-adjustable unit, so you’re not choosing between two extremes. Construction follows XYZ’s usual monotube-style damper body with a height-adjustable spring perch, letting ride height and preload be set independently of damping. It’s aimed squarely at drivers who use the car daily but want the option of a track day without swapping suspension beforehand – Audi calls this dual-use remit out directly as its target buyer.

Fitment for the Audi S3 Sedan (2013-2020)

This kit is built for the Audi S3 Sedan 8V, chassis code AU54, across the 2013 to 2020 production run. It uses XYZ’s φ55mm shock body specification with a modified rear integration to suit the 8V’s rear multi-link mounting points, so no additional rear subframe or mount fabrication is needed for this saloon body style.
