XYZ Racing Hollow Rear Brake Kit — Mercedes Benz C CLASS W204 C 350 4MATIC (2007-2014)

For fast-road and occasional circuit use in a W204 C 350 4MATIC, the rear axle does more braking work than the soft, comfort-tuned factory setup suggests, and the original rear discs are the first to heat-soak on a long mountain descent or a string of hard stops. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz C Class W204 C 350 4MATIC (2007-2014) tackles exactly that – a rear-specific upgrade, supplied as a matched pair of rear calipers and discs, that restores bite and rear-axle balance once the standard parts begin to fade.

The two-piece floating discs use hollow vanes to keep rotating and unsprung mass in check, and the kit pairs with three pad compounds – Street, Sport and Racing – so you can match the rear axle to how you actually drive. It is built to complement a front upgrade rather than mask the C 350’s nose-led, V6-over-the-front-wheels weight bias.

What this brake kit does for your 2007-2014 Mercedes Benz C Class W204 C 350 4MATIC

On the road you feel it as a firmer, more progressive rear contribution to the pedal, the kind that stops the C 350 squatting and running deep into a roundabout. The three-stage pad choice is the real lever here: Street for daily refinement and low dust, Sport for a firmer fast-road bite and wider heat range, and Racing for the heat tolerance a trackday demands. The hollow-vane disc design sheds weight from the rear corners, which sharpens how quickly the car settles once you come off the brake. Pick a caliper finish from Red, Yellow, Gold, Black or Anodized Black at no extra cost to suit the wheels it sits behind. Across all three compounds the aim is the same: a rear axle that holds its bite when the original Mercedes setup would already be going long.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is XYZ Racing’s rear-axle package for the W204 platform, built around two-piece floating discs whose hollow vanes cut rotating mass without giving up swept area. The name points to that reduced-weight disc construction, the goal being to resist the fade that kills pedal feel on repeated heavy stops. The caliper is hollow-body as standard, with a Hollow Racing upgrade – dust-cover-free, rated to 1000C, with a two-year warranty – for cars that see real circuit time. It is offered with three pad compounds – Street, Sport and Racing – so the same hardware runs as a refined road setup or a circuit-ready one depending on the friction material you fit. 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. Because it is a rear-only kit, it is meant to be specified alongside a front upgrade, balancing braking force front to rear rather than overwhelming the standard front end.
