Caliper render for this kit:

The W203 C-Class drives through its rear axle, and under hard braking the back of this saloon carries real load – particularly on the supercharged C32 and V8 C55 AMG cars, whose pace quickly overwhelms the modest rear discs Mercedes fitted as standard. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz C Class W203 Including AMG (2000-2007) swaps those rear discs and calipers for a larger, lighter assembly built to absorb repeated heat.
This is a rear-axle upgrade aimed at owners who use the car properly – fast road, the occasional track day, or simply restoring honest brake balance to a high-mileage executive saloon. Supplied as a matched pair of rear calipers and two-piece discs, it strips rotational mass while lifting thermal capacity, so the rear end keeps doing its share of the stopping.
What this brake kit does for your 2000-2007 Mercedes Benz C Class W203 Including AMG
On the road you feel it as a firmer, more consistent pedal that does not go long after a run of heavy stops down a B-road. The larger rear discs restore front-to-rear balance, so the W203 settles under trail-braking instead of leaning entirely on the fronts. Pad compound is your choice – Street for quiet, low-dust daily driving, Sport for fast road and the odd track day, Racing for circuit sessions – which lets you match bite and operating temperature to how the car is actually used. Included caliper finishes span Red, Yellow, Gold, Black and Anodized Black at no extra cost, so the kit can hide behind the wheels or make a point. The payoff is rear braking you can lean on without the fade that creeps in once the standard discs are heat-soaked.
About the Hollow Rear Brake Kit
The Hollow Rear Brake Kit is XYZ Racing’s rear-axle braking package, named for the hollow-vane rotor that cuts weight without giving up the swept area needed to shed heat. It pairs an enlarged two-piece floating disc with an upgraded caliper, hollow-body as standard, and three pad compounds – Street, Sport and Racing – so the same hardware suits a road car or a circuit build; a Hollow Racing caliper upgrade rated to 1000C with a two-year warranty is offered for hard track use. Trimming rotational mass at the rear helps the brakes cool between stops and eases load on the rear hubs and bearings. Included caliper finishes run Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, plus premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, with two-tone centre bells in five anodized colours or titanium selectable at checkout. The kit is supplied as a rear assembly and is meant to work alongside a matched front setup so overall balance stays correct.

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.
