XYZ Racing Hollow Rear Brake Kit — Mercedes Benz SLK 200 R170 (1996-2004)

The R170 SLK was built as a comfortable folding-roof roadster, not a circuit car, and its rear axle carries the weight of that steel vario-roof every time the top drops into the boot. That mass sitting over the back wheels is exactly why the standard rear brakes start to feel lazy once you use the car hard. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz SLK 200 R170 tackles that directly, fitting a larger, lighter rear setup designed to wake up the back end under braking.

Aimed at fast-road and occasional track use on the 1996-2004 SLK 200, this rear big brake kit pairs a hollow-vane two-piece floating disc with a rigid fixed caliper to cut weight and manage heat. It is the rear-axle half of a balanced upgrade for owners who want the SLK to stop with as much composure as it now carries speed.

What this brake kit does for your 1996-2004 Mercedes Benz SLK 200 R170

On the road you feel it first as a firmer, more progressive rear bite. The hollow-vane disc spins up less rotating mass than the factory item, so the rear axle reacts faster to pedal pressure and sheds heat more readily between corners. With three pad compounds you can match rear bias to how you actually drive: Street for quiet daily commuting, Sport for keener bite and a wider heat range on fast roads, and Racing for back-to-back runs where the original SLK rear brakes would already be fading. The outcome is a rear axle that helps the front under hard stops rather than locking early or going soft, with a pedal that holds its feel as the discs come up to temperature.

About the Hollow Rear Brake Kit

XYZ Racing builds this as a genuine big brake upgrade rather than a cosmetic one. It is a two-piece floating disc whose hollow-vane geometry removes material from the rotor to lower rotating and unsprung mass while keeping the swept area you need for heat capacity. A larger, stiffer fixed caliper clamps a thicker disc face, raising thermal headroom and keeping bite linear as temperatures climb. 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. Three pad compounds span the range, from Street manners through a higher-bite Sport compound to a full Racing pad for circuit days. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable. Caliper finishes are offered at no extra cost in Red, Yellow, Gold, Black or Anodized Black, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or a Custom Pantone for 150 pounds, so the kit can sit discreetly behind the wheel or read as a clear statement. Every component is sized specifically for the rear axle of the R170 platform.
