Caliper render for this kit:
The W203 C350’s 272bhp M272 3.5-litre V6 suits the car well, with a broad, linear delivery that makes the C350 quick without demanding full attention on the road. What the standard front brake package was not sized for is repeated hard stopping from high pace, where a car weighing north of 1,500 kilograms puts significant thermal demand on the front axle. Road use reveals nothing; ask more of it on circuit or a committed fast road and the gap between what the factory specified and what the car actually needs becomes clear.
Three pad compounds, Street, Sport and Racing, let you configure this XYZ Racing front big brake kit to the W203 C350’s actual use. It is a front-axle kit, a matched pair of left and right calipers and two-piece floating discs, with caliper finishes ranging from the included painted colours through premium polished and candy options for drivers running wheels where the front hardware is visible from the outside.
What this brake kit does for your 2005-2007 Mercedes Benz C CLASS W203 C 350
On a rear-wheel-drive saloon of the W203’s kerb weight, the front axle absorbs the majority of braking load under any hard deceleration. The gap between OEM and upgraded hardware is most apparent when the brakes are being used repeatedly and seriously, with motorway-exit braking on a fast-road run, or the braking zones of a track session as laps accumulate. The hollow-vane disc draws heat from the swept face faster than a solid rotor, while reduced rotating and unsprung mass sharpens response and the two-piece floating construction controls expansion. Compound selection determines the character: Street retains the quiet, low-dust feel and longevity suited to a C350 covering daily miles; Sport sharpens bite and lifts the heat range for fast-road and occasional circuit use; Racing shifts the operating window upward, delivering grip through higher temperatures at the cost of reduced cold-bite. Braided lines firm the pedal throughout.
About the Hollow Front Brake Kit
This XYZ Racing front big brake kit is a complete front-axle replacement for the W203 C-Class, substituting rotor and caliper as a matched system rather than supplementing the factory hardware piecemeal. The hollow-bodied caliper and hollow-vane disc are built to address the front braking demands of a heavy executive saloon in performance use, not comfort-biased road use. Three pad compounds are specified at order: Street is the quiet, low-dust road option balancing progressive bite with long service intervals; Sport is the middle compound for mixed-use cars doing motorway miles alongside occasional track outings; Racing is for dedicated circuit driving, needing heat to unlock peak grip. 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 configuration 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.

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.
