Caliper render for this kit:

The W203 C 180 left Stuttgart tuned for refinement, with a rear axle set up for ride comfort and an entry-spec brake package sized for everyday commuting rather than repeated heavy stops. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz C Class W203 C 180 (2000-2007) addresses that gap directly, swapping the standard rear setup for two-piece floating discs that shed heat faster and resist the fade you feel after a run of hard applications down a mountain pass or at the end of a track session.
Because the C 180 carries most of its mass over the nose, the rear brakes spend their life doing balance work rather than headline stopping. Supplied as a matched pair of rear calipers and discs, the kit gets that balance right, tightening the car under trail-braking and keeping the rear composed when you lift off mid-corner, which is exactly where a soft, comfort-biased W203 tends to feel vague.
What this rear big brake kit does for your 2000-2007 Mercedes Benz C Class W203 C 180
After fitting, the first thing you notice is consistency: the hollow-vane disc construction pulls heat out of the rotor face, so pedal feel stays firm through repeat stops instead of going long. The three pad compound options let you match the car to its use – Street for quiet, low-dust daily driving, Sport for fast-road bite and a wider heat range, and Racing for sustained circuit work. On a car as comfort-leaning as the C 180, sharper bite at the rear steadies the chassis under load and gives you brake balance you can lean on rather than guess at. Caliper finish is your call across Red, Yellow, Gold, Black and Anodized Black at no extra cost, so the upgrade reads through the wheel spokes as well as through the pedal.
About the Hollow rear brake kit
XYZ Racing’s hollow rear kit is built around two-piece floating discs whose hollow vanes cut unsprung and rotational mass while opening up the rotor’s surface for cooling. Less mass at the corner means the suspension reacts faster over poor surfaces and the brakes both reach and shed temperature more readily. The kit pairs those discs with a fixed caliper, hollow-body as standard, and a choice of three pad compounds – Street, Sport and Racing – so the same hardware suits a daily-driven W203 or a weekend track tool; a Hollow Racing caliper upgrade rated to 1000C with a two-year warranty is offered for cars run hard on circuit. Included 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 a rear-axle kit, intended to complement a front upgrade and restore proper front-to-rear balance rather than overpower the back of the 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.
