XYZ Racing Pro Racing Gravel/Snow Coilovers — Audi S3 SEDAN 8V φ55 (Modified Rear Integrated) 2013-2020

The S3 Sedan 8V carries its turbocharged four-cylinder over the front axle and drives all four corners through Audi’s quattro system, a combination that rewards suspension able to move with a loose surface rather than fight it. XYZ Racing’s Pro Racing Gravel/Snow coilover extends both front and rear damper travel specifically for that brief, giving the AU54 chassis more room to absorb ruts, compacted snow and washboard gravel before a wheel runs out of stroke.

This is the φ55 (Modified Rr Integrated) specification, built around a 55mm damper body with a rear mount reworked to sit correctly under the S3 Sedan’s integrated rear subframe. It’s the configuration XYZ Racing points AU54 owners toward for rally and rallycross use, where low-grip surfaces and repeated big hits matter more than outright spring rate.

What this coilover does for your 2013-2020 Audi S3

Extended suspension oil and nitrogen gas volume inside each damper gives the S3’s units more thermal mass than a standard road coilover, so oil temperature stays under control after sustained stage or track use instead of fading as the fluid heats up. Three external adjustment knobs let you set compression and rebound independently at each corner, useful on the S3 Sedan where quattro’s extra unsprung mass at the rear benefits from its own damping curve rather than one shared setting. Increased front and rear travel keeps the tyre in contact with loose or uneven ground for longer, which on the heavier Sedan body means less pitch under braking and more usable traction out of a slow corner. The φ55 damper bore and Modified Rr Integrated mount are specific to this AU54 fitment, so geometry stays correct under the standard rear subframe without spacers or brackets.

About the Pro Racing Gravel/Snow coilover

XYZ Racing built the Pro Racing Gravel/Snow range for rally and rallycross use, where the surface changes from one corner to the next and the suspension has to keep working through repeated hard compressions rather than a single smooth apex. Front and rear travel runs longer than on the road-biased ranges, giving the damper more distance to soak up impacts before it bottoms out. Internally, each unit carries a larger volume of suspension oil and nitrogen gas than a standard damper, which is what lets it shed heat over a long stage or session instead of the oil thinning and the damping fading with it. There’s one design detail worth knowing: the three adjustment knobs route oil through a small passage, and on big bumps that can produce a faint noise from the damper. That’s a normal characteristic of this valving rather than a fault, and the unit is rated for sustained circuit and stage use without it affecting damping consistency.

Fitment for the Audi S3 SEDAN 8V φ55 (Modified Rr Integrated) (2013-2020)

This kit is built for the 8V-generation S3 Sedan sold from 2013 to 2020, chassis code AU54, in the φ55 (Modified Rr Integrated) rear-mount configuration. Confirm your car is the Sedan bodystyle with this rear subframe arrangement before ordering, since the standard and Modified Rr Integrated mounts are not interchangeable.
