Caliper render for this kit:
The W203 C 280’s M272 V6, 231bhp from 3.0 naturally aspirated litres, sits at a level of performance where the standard front brake specification starts to reveal its limits under pressure. Push one of these facelifted W203s on a circuit, or hold the brakes hard into repeated tight bends, and the factory setup will begin to fade, pedal travel lengthening and response becoming imprecise at exactly the moment precision counts most. This XYZ Racing front big brake kit for the Mercedes Benz C Class W203 C 280 is the upgrade that restores the equation.
The W203 body is fundamentally composed for a car of its era, with geometry that rewards a driver confident enough to use the brakes deep into a corner entry. That confidence depends entirely on a consistent, progressive pedal. A big brake conversion at the front axle, a matched pair of left and right calipers and two-piece floating discs, extends the thermal headroom and sharpens modulation, making trail-braking in the W203 a deliberate technique rather than a white-knuckle calculation.
What this brake kit does for your 2005-2007 Mercedes Benz C CLASS W203 C 280
Front brakes absorb the majority of the deceleration load in any W203 C 280; weight transfer under braking loads the nose heavily, demanding more from the front discs than the rears ever see. Larger front hardware brings greater rotor mass into play, slowing the temperature climb during back-to-back braking events and keeping the pad within its operating window when the car is being driven at pace on a track day or a demanding B-road. The hollow-vane disc improves heat extraction while cutting rotating and unsprung mass, and the two-piece floating construction lets the rotor expand without distorting. Three pad compounds let the kit be specced against actual use rather than a single fixed assumption: a commuter car that visits a circuit twice a year needs different friction characteristics from a dedicated track tool, so Street, Sport and Racing mean you are not locked in. Braided lines firm the pedal, and discs come drilled or slotted at the same price.
About the Hollow Front Brake Kit
Part of the XYZ Racing performance brake range, this front big brake kit is designed for road and track applications where factory front braking hardware has been outgrown. The configuration expands swept area and rotor mass beyond the original specification, improving heat dissipation through hollow-vane construction and maintaining consistent pedal feel across sustained use, the kind of use the standard C 280 front setup was not sized to handle. The caliper is hollow-bodied as standard, with an optional Hollow Racing upgrade for serious track work that drops the dust cover, is rated to 1000C and carries a two-year warranty. The three-compound programme, Street, Sport and Racing, covers the full spectrum from everyday commuting to circuit sessions without requiring a separate kit for each discipline.
Caliper finish completes the specification when you order. Five painted colours are included at no extra cost: Red, Yellow, Gold, Black and Anodized Black. A Custom Color in any Pantone is £150, alongside premium polished-forged finishes in Titanium, Polished Gold and Polished Silver and candy finishes in Teal, Blue, Red and Orange. Two-tone centre bells in five anodized colours, or titanium, are selectable at checkout to give the installation visual coherence with the rest of the build.
Fitment for the Mercedes Benz C CLASS W203 C 280 (2005-2007)
This front brake kit is built specifically for the W203-generation C-Class in C 280 specification, covering the 2005-2007 production years that correspond with the facelift model and its M272 V6 engine. Front axle fitment only; confirm your chassis code is W203 and your build year falls within the 2005-2007 window before ordering, as earlier W203 variants and other C-Class powertrains may carry different front hub and caliper carrier geometry.

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 286–380mm (front). 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.
