XYZ Racing Hollow Rear Brake Kit — Mercedes Benz SLK 350 R171 (2004-2011)

The R171 SLK 350 stows its folding steel roof low and far back, and that mass over the rear axle tells under repeated braking. The rear discs on this roadster do more work than its relaxed GT manners suggest, and the standard rear setup fades long before the M272 3.5 V6 runs out of pace on a give-it-everything back road. This XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz SLK 350 R171 (2004-2011) puts a bigger, lighter rear stopper where the factory left margin on the table.

Built around a two-piece floating, hollow-vane disc to trim rotating mass at the rear corners, this rear brake kit is the answer for fast-road SLK 350 owners who feel the back end go soft after a sequence of hard stops. Three pad compounds let you match the kit to how you actually drive, from quiet road use to genuine circuit heat.

What this rear brake kit does for your 2004-2011 Mercedes Benz SLK 350 R171

The first thing you notice is a firmer, more confident pedal that holds its bite as the discs heat up, so the rear axle keeps contributing under trail braking instead of handing everything to the fronts. The hollow-vane disc sheds rotating mass at the rear wheels, which sharpens turn-in and lets the rear-drive chassis settle quicker between corners. Step up to the Racing pad compound and you get bite that survives back-to-back stops on a track day, where the R171’s roof-laden tail otherwise overheats a stock rear disc fast. For road-biased owners, the Street compound gives you the extra capacity without squeal or cold-bite vagueness on the morning commute, while Sport sits in between with more heat range for fast roads. Caliper colour options run from the five no-cost finishes through premium polished-forged and candy choices, so the kit reads through the wheels as cleanly as it performs.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit takes its name from the two-piece floating disc: a hollow-vane rotor machined to remove material and rotating mass while keeping the swept face and thermal capacity needed for a heavier roadster. The rear-position kit pairs that disc with an upgraded caliper across three pad compounds, Street, Sport and Racing, so the same hardware covers daily driving, spirited road use and circuit work without changing the calipers. The Street compound suits owners who simply want more headroom than the factory rear brake gives; Sport trades a little cold response for higher fade resistance; Racing is built for the repeated high-temperature stops a track session puts through the rear axle. 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. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable, and caliper finishes span no-cost Red, Yellow, Gold, Black and Anodized Black, premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or a Custom Pantone for 150 pounds for owners matching a specific build.
