XYZ Racing Hollow Rear Brake Kit — Audi TT RS (8S) MK3 (2015-2026)

The 8S TT RS puts its mass over the nose, with a 2.5-litre five-cylinder and the quattro hardware sitting ahead of the bulkhead, so the rear axle is left doing the lighter share of the braking. The XYZ Racing rear brake kit for the Audi TT RS (8S) MK3 sets out to claw back rear-axle bite, giving the car a more even front-to-rear split when you lean on the pedal hard.

This is a rear-specific upgrade, designed to pair with a stronger front setup or to firm up the back end of a car that already works its standard discs hard on track. Two-piece floating rotors shed rotating mass at the wheel, and a three-tier pad choice lets you match the kit to road, fast-road or circuit use.

What this brake kit does for your 2015-2026 Audi TT RS (8S) MK3

On a car as nose-led as the TT RS, the felt difference is at the rear: more consistent pedal feel once heat is in the system, and a back axle that resists fade through repeat stops. Lighter two-piece floating rotors cut rotational and unsprung mass, which sharpens how quickly the rear wheels react and takes a small load off the dampers. The Racing pad holds bite through a hard session where a road pad would start to glaze, the Sport pad covers fast-road work with the odd track day, while the Street compound keeps cold-stop manners for the daily commute. Caliper colour is yours to set, from Red, Yellow, Gold, Black or Anodized Black to a custom Pantone finish sitting behind the wheels.

About the Rear Brake Kit

The rear brake kit is supplied as a matched pair of left and right rear calipers and discs. The two-piece floating disc uses a hollow-vane design: material is removed from the rotor to lower rotating mass without surrendering swept area, so the rear brakes do their job with less inertia to spin up and shed. It is built specifically for the rear axle of the TT RS, where the factory discs are sized for a wheel that carries less braking duty than the front. The forged caliper is hollow-body as standard, with an optional Hollow Racing upgrade for serious circuit use that drops the dust cover and adds a 1000C rating and a two-year warranty. Pad compound is chosen at order, with Street for predictable road use, Sport for a firmer everyday bite plus light track work, and Racing for the heat tolerance a circuit session demands. Discs come drilled or slotted at the same price, fed by braided lines. Included painted colours are Red, Yellow, Gold, Black and Anodized Black at no cost, with a Custom Color in any Pantone for a small upcharge, alongside premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy (Candy Teal, Candy Blue, Candy Red, Candy Orange) finishes. Two-tone centre bells in five anodized colours, or titanium, are selectable at checkout. Across the range the intent is the same: rear braking that recovers some of the balance a front-heavy quattro coupe gives away under hard deceleration.

Fitment for the Audi TT RS (8S) MK3 (2015-2026)

This kit is mapped to the 8S-generation TT RS, the MK3 car covering model years 2015 to 2026, and fits the rear axle. The 8S chassis code and the RS designation are the two things to check against your own car, so match both to the listing before you order.
