XYZ Racing Tarmac Rally Coilovers — Audi S5 B8 4WD (Cancellation Kit for Electronic Damping) 2007-2016

The B8 S5 carries its 4.2 FSI V8 (and later supercharged 3.0 TFSI) right out over the front axle, and on a broken sealed stage that nose-weight is the enemy. Front-end float over crests, the inside-rear unloading mid-corner, and the quattro driveline trying to put 333-plus horsepower down through compressions you didn’t see until the pace notes called them – that’s the brief this coilover was built to answer.

This is the dedicated tarmac-rally specification of the XYZ Racing platform, supplied with the cancellation kit that removes the B8’s factory electronic damping (Audi Drive Select / magnetic ride) from the equation so a fixed mechanical damper can take over. It is aimed squarely at the S5 owner who runs sealed stages, hillclimbs or fast road events where the OE adaptive setup runs out of authority.

What this coilover does for your 2007-2016 Audi S5

On a B8 S5, the gains land in three places you feel immediately. The bump-absorption bias of the Tarmac Rally valving lets the front axle stay loaded over compressions and patched tarmac where a stiff circuit coilover would skip and wash wide. Body control through a long fourth-gear sweeper improves because the damper isn’t fighting the car’s own mass on rebound. And under hard braking into a hairpin, the nose stops diving onto its bump-stops, so the quattro front diff actually has weight to work with on corner exit. The cancellation kit deletes the dashboard warning and severs the magnetic-ride loop cleanly, so there’s no electronic ghost in the system once installation is finished.

About the Tarmac Rally coilover

The Tarmac Rally is purpose-tuned for one job: keeping a rally car planted across uneven sealed surfaces. The damping curve is set to absorb the jolt of larger bumps and kerb strikes without packing down, which suppresses unwanted body motion and keeps the contact patch loaded for traction. Every setting carried by this coilover comes from XYZ Racing’s own tarmac rally programme – the spring rates, damper valving and stroke have been arrived at through stage testing rather than dyno theory. The result is a coilover that lets a heavy 4WD platform like the S5 ride a rough stage with the composure of a lighter car, while still giving the driver enough mechanical adjustment to fine-tune balance across an event.

Fitment for the Audi S5 (2007-2016)

This kit is built specifically for the B8-generation S5 in 4WD form (chassis code AU28-1-C), covering production years 2007 to 2016. It is the variant that includes the cancellation module required to delete the factory electronic damping circuit, so it suits cars originally optioned with Audi’s adaptive damper system as well as those without.
