Caliper render for this kit:

The X253 and C253 GLC 250 hide a lot of mass behind a comfort-tuned brake package, and on a heavy 4MATIC compact SUV the rear axle is the first place you feel it under sustained use. The XYZ Racing Rear Big Brake Kit for the Mercedes Benz GLC 250 X253/ C253 tackles that directly, adding rear rotor and caliper capacity the standard hardware was never given much headroom for.
This is a rear-axle upgrade built around a two-piece floating disc that trims rotating and unsprung weight while lifting thermal capacity. Supplied as a matched pair of rear calipers and rear discs, it translates, on the 2016-2026 GLC 250, to steadier pedal feel when the brakes are working hard, long descents, towing, or a committed run down a B-road, without unsettling the car’s everyday manners.
What this brake kit does for your 2016-2026 Mercedes Benz GLC 250 X253/ C253
On a vehicle this heavy, rear brake fade shows up as a longer, softer pedal after a handful of hard stops; the added thermal mass here keeps the bite consistent through repeated use. The hollow-vane disc strips rotating weight from each rear corner, which sharpens turn-in and eases the load the dampers carry over broken surfaces. Three pad compounds, Street, Sport and Racing, let you match the rear axle to how you actually drive, from a quiet commute to circuit heat. A larger rear caliper improves clamping stability, giving the GLC’s stability and traction electronics a more predictable platform to manage, and keeping front-and-rear balance honest when the fronts would otherwise carry everything.
About the rear big brake kit
The kit is XYZ Racing’s route to more braking capacity without piling on weight. Its core is a two-piece floating disc, machined to cut rotating mass while retaining the friction surface area needed to absorb and shed heat; the ring is offered drilled or slotted at the same price. That rotor pairs with an uprated rear caliper and a choice of three friction compounds: Street for quiet, low-dust road use, Sport for harder fast-road work and a wider heat range, and Racing for track conditions. The caliper is hollow-bodied as standard, with a Hollow Racing upgrade available (no dust cover, rated to 1000C, two-year warranty) for serious track use. Painted caliper colours are included at no cost in Red, Yellow, Gold, Black or Anodized Black; a Custom Color in any Pantone adds 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. The kit is designed as a bolt-on rear-axle solution, sized to the GLC’s hubs and mounting points rather than adapted from a universal pattern.
Fitment for the Mercedes Benz GLC 250 X253/ C253 (2016-2026)
This kit is cut for the Mercedes Benz GLC 250 across both the X253 SUV and C253 coupé body styles, covering the 2016-2026 model span, and fits the rear axle. As the listing notes, this part requires agreement and confirmation before purchasing, so verify your exact chassis and specification against your car before you order.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 330–356mm (rear). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).


Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
