XYZ Racing Hollow Rear Brake Kit — Mercedes Benz C CLASS W203 C 230 (2000-2007)

Rear brake heat is the W203’s quiet limiter on a circuit. The C 230 Kompressor was built as a quick saloon rather than a track car, and its standard rear discs run out of thermal headroom long before a committed driver runs out of ambition. This XYZ Racing rear big brake kit for the Mercedes Benz C-Class W203 C 230 puts that right.

Being rear-wheel drive, the W203 leans on its back axle for stability under heavy braking, so rear capacity is not an afterthought on this chassis. Supplied as a matched pair of rear calipers and discs, the kit adds disc area and a fresh caliper to a corner the factory left modest, giving you a brake balance that holds its shape as the pace climbs.

What this brake kit does for your 2000-2007 Mercedes Benz C Class W203 C 230

On the road you will notice a firmer, more reassuring pedal and shorter recovery between hard stops, which matters on a car now well into its second or third decade with tired original hardware. The two-piece floating discs use hollow vanes to trim rotating mass at the rear axle, so the back end settles faster and is less inclined to lock under trail-braking. Three pad compounds let you match the kit to how you drive: Street for quiet, low-dust daily use, Sport for fast-road bite and a wider heat range, and Racing for repeated heavy stops. Because the rear works harder and fades later, the front brakes stay inside their window for longer and the whole car feels more planted into a corner.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit takes its name from the lightened disc, where the vanes are hollowed to cut rotating and unsprung mass without surrendering swept area. Less weight spinning at the rear axle means the discs shed heat more quickly and the suspension has less inertia to manage over kerbs and mid-corner bumps. The kit pairs a two-piece floating disc with an upgraded caliper that is hollow-body as standard; a Hollow Racing upgrade – no dust cover, rated to 1000C, with a two-year warranty – is offered for cars run hard on track. 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. Pad material is selectable across three compounds, Street, Sport and Racing, so the same hardware covers a comfortable commuter or a hard track day depending on what you fit. Discs come drilled or slotted at the same price, with two-tone centre bells in five anodized colours or titanium selectable at checkout. It is a bolt-on rear upgrade for owners who want real thermal capacity, not just a colour change behind the wheel.
