XYZ Racing Hollow Rear Brake Kit — Mercedes Benz SLK 320 R170 (1996-2004)

The R170 SLK 320 carries its M112 3.2-litre V6 well forward and stacks the Vario folding hardtop’s mass high over the rear axle, so the standard rear brakes were specified for relaxed boulevard work rather than sustained heat. This XYZ Racing Hollow Rear Brake Kit replaces that rear-axle hardware on the 1996-2004 Mercedes Benz SLK 320 R170 with a setup built to take repeated heavy stops without the soft, lengthening pedal owners know from a hot run down a B-road.

Rear balance matters more on a short-wheelbase roadster than most buyers expect: get the back axle hauling cleanly and the whole car settles under braking instead of pitching onto its nose. This kit suits owners who use their SLK hard on the road and the occasional track day, and who want the rear end to keep doing its share.

What this brake kit does for your 1996-2004 Mercedes Benz SLK 320 R170

The first thing you feel is a firmer, more consistent pedal once the rear axle stops cooking its pads on the second and third stop. Three pad compounds let you match bite and operating temperature to how you actually drive the SLK 320: Street for daily commuting, Sport for harder fast-road work with more bite and heat range, and Racing for a full track session. Cleaner rear braking helps the R170 stay flat and composed turning into a corner, rather than loading the front tyres and washing wide. The hollow-vane discs shed rotating and unsprung mass at the back axle, which sharpens how quickly the rear suspension reacts over a broken surface. And with caliper colours running from the five no-cost finishes through premium polished-forged and candy options, the hardware looks deliberate behind the wheel rather than aftermarket-generic.

About the Hollow rear brake kit

The Hollow rear kit is a bolt-on rear-axle upgrade built around lightweight two-piece floating discs and a matched caliper, designed to lower the rotating mass at each rear corner while adding thermal capacity over the factory parts. The hollow-vane disc removes material that does no thermal work without surrendering swept area. The three-stage pad menu is the core of it: a Street compound for road use, a Sport compound for harder fast-road driving, and a Racing compound for the track temperatures where a stock pad would glaze and fade. 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. The calipers come 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, so the rear corners can be specified to suit the car. As a rear-specific kit it is built to work with the SLK’s existing front braking balance rather than overwhelming it, keeping the bias predictable. Everything is sized for the R170 platform, so the geometry and mounting follow the car’s original rear hardware.
