XYZ Racing Hollow Front Brake Kit — Mercedes Benz CLK 55 AMG W209 (2003-2006)

The W209 CLK 55 AMG sits in an interesting bracket: AMG’s 5.5-litre V8 in a GT-leaning platform that carries genuine kerb weight in both coupe and cabriolet guise. That mass, combined with the car’s natural habitat of fast B-roads, continental touring and the occasional hard circuit session, puts sustained demands on the front braking system that the factory setup handles adequately but without much thermal reserve. The XYZ Racing front brake kit closes that gap with a pair of larger calipers and discs built to take repeated hard stops from high speed with considerably more headroom than the OEM discs allow.

There is also the AMG-owner reality: these cars are driven. The CLK 55 AMG was the most capable variant in the W209 range, and owners who chose it are not the sort who tip into corners gently. A front upgrade that returns consistent pedal feel rather than softening after a spirited sequence is a functional improvement with a clear purpose. Specify it when you order from the options above.

What this brake kit does for your 2003-2006 Mercedes Benz CLK 55 AMG W209

The hollow-vane disc at the centre of this kit channels heat out of the friction zone more effectively than a solid rotor, keeping operating temperatures in check during the repeated high-speed stops a front-engined V8 GT generates. Three pad compounds let the same hardware serve everything from commuting to circuit use without a disc swap: Street for quiet, low-dust road running, Sport for harder fast-road and occasional track work, and Racing for sustained circuit sessions.

The lighter two-piece floating disc also trims rotating and unsprung mass at the front corners, and discs are available drilled or slotted at the same price. As a front-axle-specific pair, the kit works with the car’s existing rear braking balance rather than reworking the whole system, where front and rear bias matter.

About the XYZ Racing Front Brake Kit

The disc uses a hollow-vane construction that increases internal surface area and airflow compared to a conventional vented unit, accelerating heat transfer out of the friction zone during sustained hard use, the condition that exposes the limits of standard equipment most quickly. The caliper is hollow-body forged as standard, paired with two-piece floating discs and braided lines for a firm pedal. Three pad compounds, Street, Sport and Racing, let a single set of hardware cover different driving profiles.

Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with Custom Color matching any Pantone for 150 pounds. Premium polished-forged finishes cover Titanium, Polished Gold and Polished Silver, and the candy range adds Candy Teal, Candy Blue, Candy Red and Candy Orange. Centre bells can be two-tone in five anodized colours or titanium, and the optional Hollow Racing caliper, rated to 1000C with no dust cover and a two-year warranty, is there for serious track use. The front-axle scope keeps the upgrade focused where the load is greatest in a front-heavy, large-displacement V8 layout.

Fitment for the Mercedes Benz CLK 55 AMG W209 (2003-2006)

This kit is specified for the W209 Mercedes Benz CLK 55 AMG produced between 2003 and 2006. The W209 CLK 55 AMG was available as both coupe and cabriolet, and this front kit is application-specific to the AMG 55 variant within the generation, not a shared fitment with standard CLK models that ran different front-axle hardware.
