XYZ Racing Hollow Rear Brake Kit — Mercedes Benz CLK 350 W209 (2005-2009)

The W209 CLK 350 carries its M272 V6 over the front axle and was set up from the factory for relaxed cruising rather than repeat heavy braking, which is exactly where the rear axle gets neglected. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz CLK 350 W209 addresses the back end specifically, restoring the brake balance that a front-only upgrade leaves lopsided.

Two-piece floating discs cut rotating and unsprung mass at the rear, and the kit ships with a choice of Street, Sport or Racing pad compounds so you can match the rear bias to how you actually drive this 2005-2009 coupe: boulevard miles, fast-road B-roads, or the occasional track session.

What this brake kit does for your 2005-2009 Mercedes Benz CLK 350 W209

On a front-heavy GT that dives and tips toward understeer under braking, sorting the rear matters more than most owners expect. The two-piece floating disc reduces rotating mass at each rear corner, so the back axle settles faster and stays composed when you trail-brake into a turn. The Racing compound holds bite through repeated stops where tired factory rear pads glaze and the pedal goes long; the Street compound gives firmer, more progressive feel for daily use without a cold-bite penalty, with the Sport compound bridging the two for harder road and occasional track work. Run it alongside a matching front setup and the CLK rotates predictably instead of washing wide. Painted caliper finishes in Red, Yellow, Gold, Black and Anodized Black, with a Custom Color in any Pantone available, let the hardware read as intent behind the wheels.

About the XYZ Racing Hollow rear brake kit

This is a rear-axle big brake upgrade dimensioned specifically for the W209 platform. The two-piece floating disc is the headline: its friction ring rides on an alloy bell to grow with heat without warping, and material is removed from the disc structure to drop rotating and unsprung mass while keeping the swept area a heavy GT coupe needs to shed heat. The caliper is a hollow-body forged unit as standard. Disc, caliper and bracket are supplied as a fitment-matched set, so the geometry is correct for the rear of the CLK 350 rather than a generic kit shimmed to fit. Three pad compounds span how these cars get used: Street for refined road feel, Sport for a firmer fast-road bite and occasional track, and Racing for track and hard-driving duty where heat tolerance is the priority. Painted caliper colours run 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; they are cosmetic only and do not change the braking hardware.
