XYZ Racing Tarmac Rally Coilovers — Audi S1 SPORTBACK 8X (Modified Rear Integrated) 2014-2018

Few superminis carry a genuine rally pedigree, but the S1 Sportback 8X does: a short-wheelbase quattro layout with a Haldex-driven rear axle, built to shift weight fast and put it down through all four corners. That same character which makes the 8X so eager on a stage also punishes soft, road-biased dampers the first time a sealed tarmac stage throws a compression, a crest or a mid-corner bump at speed.

XYZ Racing’s Tarmac Rally coilover kit for the 2014-2018 Audi S1 Sportback 8X (Modified Rr Integrated) is set up for exactly that environment. It’s built for sealed-stage tarmac rally work, where the car needs to absorb broken road surfaces without losing the front-end bite that makes the S1’s quattro drivetrain worth having in the first place.

What this coilover does for your 2014-2018 Audi S1 SPORTBACK 8X (Modified Rr Integrated)

Fitted to the 8X, this kit keeps the tyre loaded through the kind of surface changes a road-going setup simply wasn’t built to handle – broken tarmac, patched stage sections, and the compressions that come after a crest. The damper tuning is aimed at controlling body movement under those hits rather than just stiffening the ride, so the quattro system keeps working with a consistent contact patch instead of fighting an unsettled chassis. On a short-wheelbase car like the S1, that control matters more than outright stiffness: it’s what keeps direction changes predictable when the surface underneath you isn’t. The result on the road or stage is a car that settles quicker after a bump and holds its line through the next input, rather than needing a correction.

About the Tarmac Rally coilover

This is a damper set-up built specifically around Tarmac Rally use, and the tuning reflects that brief directly. It’s calibrated to soak up the impact of uneven pavement and larger bumps without transmitting that shock straight into the body, which is what lets the tyre stay planted and keep generating traction instead of skipping across the surface. XYZ built the valving and spring rates around its own tarmac rally programme, so the settings on this kit aren’t generic road-and-track compromises – they come from what the team has run on actual stages. The intent is a chassis that stays composed and predictable through repeated hard hits, giving the driver a stable platform to work from rather than one that’s constantly correcting itself.

Fitment for the Audi S1 SPORTBACK 8X (Modified Rr Integrated) (2014-2018)

This kit is built for the Audi S1 Sportback 8X, chassis code AU43-1, covering the 2014-2018 production run. The Modified Rr Integrated spec accounts for the 8X’s factory rear suspension design, pairing an integrated damper-and-spring unit at the rear rather than assuming a straight swap onto the standard mounting points.
