XYZ Racing Hollow Rear Brake Kit — Mercedes Benz GLC 43 COUPE 4MATIC C254 (2023-2026)

At more than two tonnes, the C254 GLC 43 Coupe leans hard on its rear axle every time you scrub speed from a motorway cruise or a quick B-road. The 4MATIC layout moves load around under power and recovers it under braking, and the factory rear discs were sized for road manners rather than repeated heavy stops. This is where the XYZ Racing Rear Big Brake Kit earns its place on the 2023-2026 GLC 43 Coupe.

Built around two-piece floating discs that trim rotating and unsprung mass, the kit gives the rear of this Mercedes Benz performance SUV more thermal headroom and a firmer, more progressive pedal. Supplied as a matched pair of rear calipers and rear discs, it leaves pad compound to you, Street, Sport or Racing, depending on whether the car sees daily duty, fast roads, or the occasional circuit day.

What this brake kit does for your 2023-2026 Mercedes Benz GLC 43 Coupe 4matic C254

The first thing you notice is bite. The discs come up to temperature quickly and shed heat faster than the standard items, so the pedal stays firm through a sequence of hard stops instead of going long and vague. On a heavy 4MATIC coupe, that sinking-pedal fade tends to announce itself first at the rear, and this kit pushes that threshold well back. Cutting rotating mass at the rear axle also takes a little strain off the bearings and hubs and tidies up how the car settles into a corner. Fit the Racing compound for repeat track stops, the Sport compound for hard fast-road use and a wider heat range, or Street for quiet, low-dust daily braking. A composed rear axle keeps front-and-rear balance predictable when you brake deep into a turn.

About the rear big brake kit

XYZ Racing’s rear big brake kit is a direct rear-axle upgrade aimed at performance road and track use. It uses two-piece floating discs that remove material without giving up swept area, lowering rotating mass and helping the brakes run cooler under sustained load; the ring is offered drilled or slotted at the same price. The kit ships with three pad compounds: Street for quiet, low-dust road use, Sport for harder road work and a wider heat range, and Racing for circuit use, so the same hardware suits very different driving. The caliper is hollow-bodied as standard, with a Hollow Racing upgrade (no dust cover, rated to 1000C, two-year warranty) for serious track use. Painted caliper colours come at no cost in Red, Yellow, Gold, Black or Anodized Black; a Custom Color in any Pantone is GBP 150, and premium polished-forged finishes (Titanium, Polished Gold, Polished Silver), candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) and two-tone or titanium centre bells are all available. Everything is sized specifically for the rear of this car rather than adapted from a generic kit, which keeps the balance sensible on a machine as nose-heavy as the GLC 43.
