XYZ Racing Hollow Rear Brake Kit — Mercedes Benz C CLASS W203 C 280 (2005-2007)

The facelifted W203 C 280 leans on its front axle harder than most owners expect. The M272 V6 sits well forward of the bulkhead, and Mercedes tuned the standard car for autobahn refinement rather than repeat heavy stops – so the rear of the car does the least braking work and is the first end to feel vague once the discs are hot. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz C Class W203 C 280 targets exactly that weakness.

This is a rear big brake kit built to restore front-to-rear balance, supplied as a matched pair of rear calipers and two-piece discs that strip rotating and unsprung mass from the back hubs. Three pad compounds – Street, Sport and Racing – let you match the kit to how the car is actually driven, from a daily-driven saloon to a fast-road or circuit setup.

What this brake kit does for your 2005-2007 Mercedes Benz C Class W203 C 280

On the W203, the most noticeable change is a rear axle that stays composed under trail-braking instead of going light and unsettling the car on corner entry. The hollow-vane disc construction lightens each rear rotor, which lifts load off the multi-link rear suspension and gives the back end a cleaner, more planted feel as you brake toward a turn. With the Racing pad compound the rear bites consistently through a full session rather than glazing after a handful of hard stops down from autobahn speed. Run the Street compound for everyday driving and a quieter, lower-dust commute, step up to Sport for fast road and the odd track day, then switch to Racing when you take the C 280 on track. The result is a brake balance that no longer pushes everything onto the front discs.

About the Hollow Rear Brake Kit

The kit is named for its hollow-vane rotor construction, which removes material from the disc to cut both rotating mass and thermal weight at the rear axle. Less rotating mass at the hub means the rear brakes spin up and shed heat more readily, helping resist the fade that comes from working an undersized factory rear setup hard. The two-piece floating disc pairs with a fixed caliper, hollow-body as standard, that resists the flex of the original sliding arrangement, so pedal feel stays firm as temperatures climb; a Hollow Racing upgrade – dust-cover-free, rated to 1000C, with a two-year warranty – is offered for circuit cars. Pad choice is central to the system: Street for stock-feel road use, Sport for a more aggressive fast-road bite, and Racing for circuit work where consistency matters most. Included caliper finishes are 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 come drilled or slotted at the same price, with two-tone centre bells in five anodized colours or titanium selectable at checkout.
