XYZ Racing Street Advanced Coilovers — Audi A5 B8 SPORTBACK 4WD 2009-2016

The B8 A5 Sportback’s quattro drivetrain adds real mass over the front axle, and on the standard air or steel springs that weight rolls forward hard under braking and washes the nose wide mid-corner. XYZ Racing’s Street Advanced coilover kit is built for exactly this – a road-focused set-up that firms up body control without turning the Sportback into a track car you have to tolerate on the M62.

This is the specification most B8 owners actually order: a fast-road platform with enough range to sharpen the car for a track day and settle back down for the school run afterwards. On a 4WD Sportback carrying extra driveline weight, that adjustability matters more than on the lighter front-drive A4 saloon it’s related to.

What this coilover does for your 2009-2016 Audi A5

Dropping the ride height and fitting a stiffer, adjustable spring rate directly counters the B8 Sportback’s nose-heavy quattro stance – body roll drops, the front end stops diving under braking, and turn-in response sharpens noticeably compared with the factory set-up. The 720-way damping adjustment means you can run the compression and rebound softer for the daily commute and firm everything up before a track session, without swapping parts. Lowering the centre of gravity also reduces the pitch and squat that quattro cars are prone to under hard acceleration out of a corner, keeping the chassis flatter and the steering more honest. For a Sportback that’s carrying more weight than the standard A5 coupe, that stability under load is the difference the driver actually feels.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s most widely specified coilover line, refined over several years of development and proven across the marque’s international race programmes before being brought down to a road-legal, street-focused spec. It’s built for two overlapping jobs – comfortable daily use and the occasional track day – rather than being tuned exclusively for one or the other. The headline figure is 720 damping settings, giving a genuinely wide window between compliant and firm rather than the handful of clicks some kits offer. That range is what makes it suit drivers who want their B8 A5 sharpened for enthusiastic driving without giving up a usable ride on UK roads. XYZ positions it as core equipment for anyone chasing more speed and more control from their car, and the adjustment count is there specifically so you can tune toward whichever side of that trade-off you need on a given day.

Fitment for the Audi A5 (2009-2016)

This kit is built for the Audi A5 B8 Sportback in quattro (4WD) guise, chassis code AU28, covering the 2009 to 2016 production run. Fitment is specific to the 4WD Sportback body – confirm your logbook shows quattro drivetrain and Sportback bodystyle before ordering, as the coupe and front-wheel-drive variants use different mounting and spring specifications.
