Caliper render for this kit:
The W204 C 350 is a heavier, more powerful proposition than casual glances suggest: over 1,500 kilograms of platform with a 3.5-litre V6 producing north of 270 bhp. Under hard braking from speed, the front axle is carrying the overwhelming share of deceleration load, and the standard single-piston floating calipers Mercedes specified were calibrated for a long service life on public roads, not for repeat hard stops at Cadwell Park or a back-road descent where braking points come fast and close together.
This XYZ Racing front big brake kit replaces that standard hardware with larger-diameter two-piece floating discs and a multi-piston caliper, a matched pair for the front axle, giving the W204 C 350’s front end the thermal capacity to handle the kind of repeated braking loads that overwhelm OEM equipment, and letting owners specify the caliper finish that suits the rest of the build.
What this brake kit does for your 2007-2014 Mercedes Benz C CLASS W204 C 350
The big brake upgrade shifts the thermal envelope at the front axle substantially. Larger discs mean more swept area, so heat generated by repeated hard stops dissipates across a greater mass rather than concentrating into the standard-diameter disc, and the hollow-vane construction draws that heat from the swept face faster still. For a C 350 being driven on track, where brake temperatures can reach points at which OEM compounds begin to fade mid-session, that headroom matters. Three pad compounds, Street, Sport and Racing, let the buyer match friction material to how the car is actually used, from daily commuting to committed circuit laps. Reduced rotating and unsprung mass quickens response, the two-piece floating disc controls expansion, and braided lines keep the pedal firm.
About the Hollow Front Brake Kit
Built around hollow-vane front discs, this XYZ Racing kit uses a casting geometry that reduces unsprung rotating mass compared to conventional vented castings while maintaining the structural integrity the front axle demands under heavy braking loads. The caliper is hollow-bodied as standard, and its multi-piston layout delivers more consistent pad contact across the full friction face than a single floating piston, reducing the taper wear that progressively undermines pedal feel in original equipment over time. Pad compound is selected at order, giving flexibility for owners running the same car in different contexts across the calendar. Discs come drilled or slotted at the same price, and an optional Hollow Racing caliper upgrade for serious track work drops the dust cover, is rated to 1000C and carries a two-year warranty.
Caliper finish completes the build 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, with premium polished-forged finishes in Titanium, Polished Gold and Polished Silver, plus candy finishes in Teal, Blue, Red and Orange. Two-tone centre bells in five anodized colours, or titanium, are selectable at checkout; on a W204 C 350 running 18- or 19-inch alloys, the caliper is very much part of the visible face of the car.
Fitment for the Mercedes Benz C CLASS W204 C 350 (2007-2014)
This kit is developed for the W204 platform, the third-generation C-Class produced from 2007 through to 2014, in C 350 specification. If running a 4MATIC variant, confirm front hub geometry and caliper-mount dimensions match the rear-drive specification before ordering, as all-wheel-drive versions can differ at the carrier. Chassis code, year and drivetrain configuration are the three checkpoints worth verifying.

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.
