XYZ Racing Hollow Rear Brake Kit — Mercedes Benz C CLASS W204 C 63 AMG (2007-2014)

The W204 C 63 AMG carries its 6.2-litre M156 V8 well forward, and that iron-block mass piles onto the front axle every time you brake from speed. On the road it is manageable, but on a circuit the rear end is doing quiet, constant work to keep the car settled – and that is the half of the brake system most owners upgrade last. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz C CLASS W204 C 63 AMG goes after the back axle specifically.

Supplied as a matched pair of rear calipers and discs, it is built for the stability side of braking: holding the tail in line under trail-braking and resisting the fade that creeps in after a few hard laps. Pad compound runs from Street through Sport to a full Racing compound, so the kit can sit quietly behind a daily-driven C 63 or take sustained abuse on track.

What this brake kit does for your 2007-2014 Mercedes Benz C CLASS W204 C 63 AMG

After fitting, the first thing you feel on the W204 is a firmer, more progressive rear pedal under hard braking – the back axle bites cleanly instead of going vague as heat builds. The two-piece floating discs use hollow vanes to trim rotating and unsprung mass at the rear, which the C 63’s busy back end appreciates over kerbs and mid-corner bumps. Move up to the Sport or Racing pad compound and the kit holds its bite through repeat stops, so brake balance stays predictable when you lean on the car late into a braking zone; Street keeps things quiet and low-dust for daily use. For anyone who tracks the M156, that consistency is the difference between committing to a late stop and backing off into every corner.

About the Hollow rear brake kit

XYZ Racing builds this as a rear-axle big brake kit, with the two-piece floating disc and hollow-vane construction that gives the range its name. Removing material from the vanes reduces rotating mass without surrendering thermal capacity, helping the brakes shed heat between stops rather than soaking it up until they fade. The larger rotor gives the caliper more leverage and more pad surface to work against than the standard C 63 rear arrangement, and the caliper is hollow-body as standard, with a Hollow Racing upgrade rated to 1000C and a two-year warranty for sustained track use. Three pad compounds cover the spread of use: Street for road manners, Sport for fast-road and occasional track work, and Racing for sustained circuit sessions. 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, so the upgrade reads as deliberate behind the wheel spokes rather than an afterthought.
