XYZ Racing Hollow Rear Brake Kit — Audi TT RS 8J (2009-2014)

The 8J TT RS carries its 2.5-litre five-cylinder turbo well forward of the front axle, and that mass bias means the rear brakes spend most of their working life managing stability rather than raw stopping force. The XYZ Racing rear brake kit for the Audi TT RS 8J targets the back axle specifically, pairing lighter two-piece floating discs with a forged caliper that keeps pedal response steady while the nose-heavy front end does the heavy lifting into a corner.

On a quattro coupe that hooks up and fires out of slow corners, rear brake feel matters more than the spec sheet suggests. This kit is built to hold a consistent front-to-rear bias under repeated heavy use, so the back end stays settled on trail braking instead of going vague as disc temperatures climb.

What this brake kit does for your 2009-2014 Audi TT RS 8J

The two-piece floating disc sheds rotational and unsprung mass at the rear, which sharpens turn-in and takes a little workload off the 8J’s busy front suspension. The forged caliper gives you a firmer, more linear pedal than the sliding factory setup, so brake modulation is easier to judge at the limit. Three pad compounds let you tune the rear axle to your use: Street for quiet, low-dust road duty, Sport for fast-road bite, and Racing for sustained circuit sessions where fade resistance is the priority. The net result is a TT RS that brakes deeper and rotates more honestly, with rear-end behaviour you can lean on rather than guess at.

About the Rear Brake Kit

This is a dedicated rear upgrade for the Audi TT RS 8J, supplied as a matched pair of left and right rear calipers and discs. It is built around hollow-vane two-piece floating discs that cut rotating weight while improving heat shedding and wet-weather bite, with the choice of drilled or slotted faces at the same price. The forged caliper clamps evenly across the pad, holding torque consistent as the brakes load up, and is hollow-body as standard; an optional Hollow Racing upgrade adds a no-dust-cover, 1000C-rated build with a two-year warranty for hard track use. Braided lines keep the pedal firm. Pad choice spans three compounds, Street, Sport and Racing, so the same hardware covers everything from a daily-driven coupe to a hard-used track car. Included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for a small upcharge, plus premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy (Candy Teal, Candy Blue, Candy Red, Candy Orange) finishes. Centre bells can be upgraded to two-tone in five anodized colours, or titanium, selectable at checkout. Everything is sized to the rear axle of the 8J specifically rather than adapted from a generic kit, which keeps the brake balance where Audi’s chassis engineers intended it.
