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

The W209 CLK 55 AMG carries its 5.4-litre M113 V8 well ahead of the front axle, so the rear brakes spend most of their life doing the lighter half of the work. That changes the moment you start leaning on the car: a quick succession of stops from three-figure speeds, or a few hard laps, and the standard rear discs heat-soak until the pedal goes long.

This XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz CLK 55 AMG W209 (2003-2006) rebuilds the back axle’s braking around heat management. Two-piece floating rotors shed temperature faster and trim a little unsprung weight, and three pad compounds let you set the rear bite to suit a road car, a fast-road set-up, or circuit use.

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

On a heavy GT coupe like this, rear brake stability is what keeps the back of the car settled when you trail the pedal into a corner. The two-piece floating disc resists the fade that creeps in after repeated heavy stops, so the pedal stays where you left it rather than sinking through a hard run. Matching the rear pad compound to the front, Street for daily driving, Sport for harder road use and occasional track, Racing for circuit work, lets you tune brake balance instead of fighting an over- or under-braked rear axle. The painted caliper finish is yours to specify, from a discreet Black through Red, Yellow, Gold and Anodized Black, with a Custom Color in any Pantone available, so the upgrade reads through the rear wheels exactly as much as you want it to.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is a rear-axle disc and caliper package built specifically around heat. It pairs a two-piece floating disc, whose friction ring rides on an alloy bell and whose vented internal construction increases the surface area working to pull heat out of the disc face, with a hollow-body forged caliper as standard, reducing rotational and unsprung mass at the back of the car. It comes with a choice of three pad compounds, Street, Sport and Racing, so it can be specified as a like-for-like quality replacement or as a genuine performance step, depending on how the CLK is used. Painted calipers are offered in Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for a small upcharge and premium polished-forged or candy finishes available. Because this is a rear-specific kit, it is designed to complement a front upgrade or to refresh tired factory rears without upsetting the W209’s standing brake balance.

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

This kit is cut for the rear axle of the W209-generation Mercedes Benz CLK 55 AMG built from 2003 to 2006. It is matched to the 55 AMG variant specifically rather than the wider CLK range, so the rotor and caliper geometry suits the AMG rear hubs of these model years. Confirm your build year falls inside the 2003-2006 span before you order.
