XYZ Racing Rear Brake Kit — Peugeot 308 GTI (T9) (2013-2026)

The 308 GTI (T9) puts almost all its mass and its braking effort over the front axle, which is exactly where a front-driven Peugeot Sport hatch wants it – and exactly why the rear discs run cool and underused until you push the car hard. On a circuit or a quick B-road, that imbalance shows up as a front end doing the thermal work while the rear contributes little. This XYZ Racing Hollow Rear Brake Kit for the Peugeot 308 GTI (T9) rebalances that equation.

It is a rear-axle upgrade – a matched pair of left and right calipers and two uprated discs – aimed at owners who want the back of the car to carry more of the braking load, sharpening pedal feel and giving the front brakes some relief during repeated hard stops. Pad compound runs from Street through Sport to Racing, so the kit suits everything from a fast-road 308 GTI to one that sees regular track time.

What this brake kit does for your 2013-2026 Peugeot 308 GTI (T9)

On the road you will notice a firmer, more progressive pedal and better resistance to the soft, long-travel feel that creeps in once the factory rears get warm. On track, the gain is consistency: a rear axle that contributes more braking torque shifts thermal load off the front discs, which is where a nose-heavy 308 GTI normally cooks its pads first. The hollow-vane disc sheds heat faster than a solid rear rotor, so the kit holds its bite through longer braking zones. The Racing pad compound raises the temperature ceiling further for circuit use, the Sport pad handles fast road and the odd lap, and the Street compound keeps cold bite and low dust manners for daily driving. The result is a 308 GTI that stays composed under repeated heavy braking and trail-brakes into corners with more rear stability.

About the Hollow rear brake kit

XYZ Racing’s Hollow rear brake kit is built around a lightweight disc that uses a hollow-vane internal structure to cut rotating mass while increasing the surface area available to shed heat. Less rotating mass at the rear axle reduces the load the suspension has to control, and the extra cooling capacity keeps the friction surface in its working range during sustained use. The rotors are two-piece floating discs run on braided lines, so the face stays flat and the pedal stays firm under heat. The kit pairs the disc with a fixed caliper and a choice of three pad compounds – Street, Sport and Racing – so the same hardware covers a road-biased build or a track-focused setup. Calipers are hollow-bodied as standard, with an optional Hollow Racing upgrade (no dust cover, rated 1000C, two-year warranty) for serious circuit work. Painted finishes are included free in Red, Yellow, Gold, Black and Anodized Black; a Custom Color in any Pantone is +£150, with premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange finishes available. Discs are drilled or slotted at the same price, and two-tone anodized or titanium centre bells can be added at checkout. As a rear-specific kit it is built to complement the front brakes rather than overwhelm them, preserving the front-to-rear bias the 308 GTI relies on.
