XYZ Racing Hollow Front Brake Kit — Mercedes Benz S CLASS W221 S 65 AMG (2005-2013)

Stopping a car of the W221 S 65 AMG’s calibre, more than 2,100 kilograms with a twin-turbocharged 6.0-litre V12 and genuine grand-touring pace, places the front axle under thermal loads that few AMG saloons of that era could match. The factory braking system is sized for the car’s mass, but sustained hard use on fast roads or track days exposes the limits of conventional disc construction when the same deceleration event arrives in close succession.

The XYZ Racing front brake kit is built for the 2005-2013 S 65 AMG W221. It is a front-axle kit: a matched pair of front calipers and two-piece floating discs for the left and right corners, the position carrying the heaviest stopping load on any rear-wheel-drive saloon under hard deceleration. The hardware is sized for what this platform generates.

What this brake kit does for your 2005-2013 Mercedes Benz S CLASS W221 S 65 AMG

The hollow-vane disc manages heat more efficiently than a solid casting, which has direct consequences on a car weighing over two tonnes that can generate very high braking forces at the front. Thermal fade, the progressive softening of pedal feel as disc and fluid temperatures rise, is a real concern on long, fast descents or consecutive braking events, and the vented hollow architecture pushes that exposure further away. The two-piece floating disc rides on an alloy centre bell that trims unsprung and rotating mass, so the suspension settles faster between stops. Three pad compounds let you match the setup to the car’s real life: Street preserves the quiet, low-dust pedal feel expected from a luxury saloon, Sport suits fast-road and occasional spirited driving with more bite and heat range, and Racing handles the sustained thermal loads the V12’s output can demand. Braided stainless lines hold pedal travel consistent as the system heats, which matters on a car that spends most of its mileage on public roads rather than a circuit.

About the Front Brake Kit

The disc construction tackles two constraints at once, heat retention during repeated heavy stops and rotational mass, while the forged caliper provides the clamping rigidity to use the larger swept area. The caliper is hollow-bodied as standard and ships in your choice of painted finish at no extra cost: Red, Yellow, Gold, Black, or Anodized Black. Custom Color matches any Pantone reference for £150. For something more striking, the polished-forged finishes run to Titanium, Polished Gold and Polished Silver, with candy finishes in Teal, Blue, Red and Orange. Discs are offered drilled or slotted at the same price, two-tone centre bells come in five anodized colours or titanium, and serious track users can specify the Hollow Racing upgrade, which removes the dust cover, is rated to 1000C and carries a two-year warranty. Every option is chosen when you order, so the installation reads as deliberate through the S 65 AMG’s wheel arches rather than advertising itself as a bolt-on addition.

Fitment for the Mercedes Benz S CLASS W221 S 65 AMG (2005-2013)

This kit covers the Mercedes Benz S Class W221 in S 65 AMG specification from 2005 through to 2013, spanning both pre-facelift and post-facelift variants of the 6.0-litre V12 twin-turbo platform. The S 65 AMG ran exclusively rear-wheel drive throughout the W221 generation, so there is no 4MATIC variant in this specification to cross-reference against. Confirm your chassis position (front) and exact model designation before ordering.
