Caliper render for this kit:

The W203’s rear axle has always been the quiet partner in how this car stops. Mercedes built the C 240 for relaxed, long-legged motorway work, which means modest rear rotors and a pedal that starts to go soft once the discs have had a few hard stops in them. This XYZ Racing rear big brake kit for the Mercedes Benz C Class W203 C 240 puts larger, better-cooled discs and fresh calipers behind the rear wheels, supplied as a matched pair, so the back of the car carries its proper share of the braking load.
It is a rear-specific upgrade rather than a styling token. Three pad compounds – Street, Sport and Racing – let you set the kit up around how the car is actually driven, from a high-mileage V6 saloon doing daily miles to a weekend that includes a few committed stops.
What this brake kit does for your 2000-2007 Mercedes Benz C Class W203 C 240
The first thing you feel is a firmer, more progressive pedal, because the larger two-piece rear rotor gives the system more thermal headroom before the bite starts to drop away. On a nose-heavy RWD saloon like the W203, getting the rear axle to contribute more under braking settles the car on turn-in and takes some of the workload off the front discs that normally do almost everything. The Racing compound holds up to repeat heavy stops without the long pedal that standard pads give once heat-soaked, while the Sport pad adds a wider heat range for fast road and the Street pad keeps cold bite sensible and dust low for everyday driving. Included caliper finishes – Red, Yellow, Gold, Black and Anodized Black at no extra cost – mean the visible upgrade through the rear wheels matches the rest of the car.
About the Hollow rear brake kit
The Hollow rear brake kit is XYZ Racing’s lightweight take on a rear big brake upgrade. The hollow-vane disc construction is aimed at shedding rotating and unsprung mass at the rear axle, which matters on a comfort-tuned chassis like the W203 where the standard rear setup is conservative. The kit pairs an uprated two-piece floating disc with a matched caliper, hollow-body as standard, and a choice of three pad compounds – Street for OEM-style behaviour, Sport for sharper road bite and heat range, and Racing for sustained high-temperature work; a Hollow Racing caliper upgrade rated to 1000C with a two-year warranty is offered for circuit use. 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 are drilled or slotted at the same price, with two-tone centre bells in five anodized colours or titanium selectable at checkout. It is engineered specifically for the rear position, so it complements rather than overwhelms the front brakes and is designed to improve front-to-rear balance under load.
Fitment for the Mercedes Benz C Class W203 C 240 (2000-2007)
This kit is built for the W203-generation C-Class in C 240 specification, covering the 2000 to 2007 production span. It is a rear-axle fitment, so it works alongside your existing front brakes to rebalance how the car stops. Confirm your exact chassis and trim before ordering so the disc and caliper sizing match your car.

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.
