XYZ Racing Hollow Rear Brake Kit — Mercedes Benz SLK 230 R170 (1996-2004)

The R170 SLK 230 puts more mass over its tail than its compact roadster silhouette suggests. The folding vario-roof stows in the boot, loading the rear axle, and on a supercharged Kompressor that has to be hauled down from real speed the rear brakes do more work than the spec sheet implies. This XYZ Racing Hollow Rear Brake Kit replaces the standard rear setup on the SLK 230 R170 with hardware built to take repeated heat without the pedal going long.

It is a rear-axle upgrade for owners running their SLK harder than a Sunday cruise: fast B-road work, the occasional track session, or simply a car that now needs to stop with the authority a modern driver expects. Match the rear to a front kit and you keep a brake balance that stays consistent once the discs are hot.

What this brake kit does for your 1996-2004 Mercedes Benz SLK 230 R170

On the road you feel it first as a firmer, more progressive pedal, the kind that lets you lean on the rear brakes late into a corner without the squirm a tired standard setup gives a short-wheelbase RWD car. Three pad compounds let you set the car up for how you actually drive it: Street for daily use, Sport for harder fast-road duty with more bite and heat range, and Racing for track heat where fade resistance matters more than cold-stop manners. Because this is a rear kit, the biggest gain shows up under trail-braking and on long downhill sequences, where the SLK’s rear axle is working to keep the nose settled. Stopping distances tighten, but the real change is repeatability, as the tenth stop feels like the first. You can also colour-match the calipers so the upgrade reads through the wheels.

About the Hollow rear brake kit

The Hollow rear brake kit is XYZ Racing’s bolt-on rear-axle braking package for the SLK 230 R170, supplied as a matched pair of rear calipers, two-piece floating discs and pads sized for this chassis rather than adapted from a universal fit. The hollow-vane disc lowers rotating and unsprung mass while keeping the swept area you need for heat capacity. It is offered with three pad compounds, Street, Sport and Racing, so the same hardware covers a daily-driven car, a fast-road build and one that sees track time without swapping the underlying kit. 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 are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable, and 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. The focus of a rear kit like this is heat management and consistent clamping under repeated use, so the pedal holds firm where an older standard rear setup would already be softening. As a rear-specific kit it is built to pair with a front upgrade, keeping front-to-rear balance correct, which matters on a light, short car like the SLK, where too much rear bias makes the tail nervous under braking.

Fitment for the Mercedes Benz SLK 230 R170 (1996-2004)

This kit is cut for the R170 SLK 230 built from 1996 to 2004, the first-generation Kompressor roadster, not the later R171. It fits the rear axle of the standard SLK 230 R170, so confirm your chassis code reads R170 before ordering. Pick your pad compound and caliper colour to match the spec to your car.
