XYZ Racing Street Advanced Coilovers — Audi S3 SPORTBACK 8V φ55 2013-2020

The 8V S3 Sportback carries its EA888 lump and Haldex hardware low and forward, and on the standard setup that mass telegraphs straight through the front axle under trail-braking – the nose dives, the rear stays comparatively aloof, and the whole car feels like it’s making decisions without you. Street Advanced is XYZ Racing’s answer for owners who split their weeks between the daily commute and the odd trackday, not a full competition strip-out.

With 720 damping adjustment increments on tap, this kit lets you firm up the front to check that dive before you’ve even touched the springs, then back the rear off again for the motorway run home. It’s built to live on the car full-time rather than get swapped in and out for high days.

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

Firming the front damping curtails the nose-dive that comes with the Sportback’s front-heavy, Haldex-assisted layout, sharpening turn-in response without you needing to relearn the car’s braking points. The 720-way adjustment range gives genuinely usable separation between a comfort setting for potholed B-roads and a track setting that keeps the front tyres loaded through direction changes – not two clicks that feel identical. Lowering the ride height also drops the centre of gravity, which works with the quattro/Haldex system’s inherent grip rather than fighting the extra roll a taller stance invites. Where the standard suspension telegraphs bump-thump through the cabin at speed, the adjustable valving lets you tune out harshness on UK B-roads while still firming things up for a circuit session, and the Sportback’s added weight over the hatch is better controlled at both ends without the ride turning wooden.

About the Street Advanced coilover

Street Advanced is the volume model in XYZ Racing’s range, developed over several years of in-house testing and validated through use across motorsport competition worldwide. The core of the kit is its 720-way damping adjustment, giving owners a wide, genuinely distinguishable band between a compliant road setting and something stiff enough for a trackday, rather than a handful of coarse steps. XYZ pitches this specifically at drivers who split their car between normal road use and the occasional track outing, which is exactly the compromise most S3 owners are trying to solve. It’s built as the kit you fit once and leave on the car, not a specialist part you swap in for a single session and remove afterwards. For an EA888-powered quattro chassis carrying real weight over the front axle, that kind of everyday-usable adjustability is the point, not a bonus spec on a sheet.
