XYZ Racing Hollow Rear Brake Kit — Mercedes Benz SLK 280 R171 (2004-2011)

The R171 SLK 280 carries its folding steel vario-roof high and well rearward, so the back axle does more work than this roadster’s boulevard reputation suggests, especially when you trail the brake into a tightening bend. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz SLK 280 R171 targets exactly that, swapping the standard rear setup for two-piece floating discs that strip unsprung weight while holding temperature under repeated stops.

This is rear-axle hardware for owners who treat the M272-powered SLK as more than a cruiser. Run front-to-rear with a matched front setup, it firms the pedal and keeps the tail of the car settled when you brake deep and turn in, rather than letting the back go light.

What this brake kit does for your 2004-2011 Mercedes Benz SLK 280 R171

The first thing you feel is a firmer, more linear pedal. The hollow-vane disc cuts rotating and unsprung mass at each rear corner, so the wheels react faster over mid-corner bumps and the rear of the SLK 280 stays composed under load. Three pad compound options let you match bite and temperature range to how you actually drive: Street for road commuting, Sport for keener fast-road work with a wider heat range, and Racing for back-to-back circuit runs. The Racing compound holds friction through heavy, repeated stops where a factory rear pad would start to fade. On a rear-drive roadster, sharper rear braking also translates to better stability the moment you load the rear axle on corner entry.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit takes its name from its two-piece floating disc: a hollow-vane rotor engineered to remove material where it does not contribute to braking, lowering thermal mass and unsprung weight without giving up rigidity. Less mass at the disc means quicker heat dissipation and a faster-reacting wheel. The caliper body is hollow as standard, with an optional Hollow Racing upgrade for serious track use, rated to 1000C with no dust cover and a two-year warranty. The kit fits the rear axle as a complete pair, pairing the hollow-vane discs with calipers finished in no-cost Red, Yellow, Gold, Black or Anodized Black, premium polished-forged Titanium, Polished Gold or Polished Silver, candy Teal, Blue, Red or Orange, or a Custom Pantone for 150 pounds. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable. Pad compound is specified separately across Street, Sport and Racing, so identical hardware suits a road-biased SLK or one that sees regular track time. It is intended to run alongside a matched front kit for balanced front-to-rear braking, which is where a rear-specific upgrade earns its keep instead of working in isolation.

This kit is built specifically for the R171-generation Mercedes Benz SLK 280, covering the 2004 to 2011 production span.

Caliper colour and pad compound are both chosen when you order.
