XYZ Racing Hollow Rear Brake Kit — Bmw Z3 M-COUPE/ ROADSTER (1998-2002)

The Z3 M-Coupe and Roadster carry their mass over a stubby 2.46-metre wheelbase, and that short rear end is exactly why the back axle repays attention. Lift or brake mid-corner in one of these and the tail moves first; a rear brake that bites cleanly and sheds heat is part of keeping that movement on your terms rather than the car’s. The XYZ Racing Hollow Rear Brake Kit for the BMW Z3 M-Coupe / Roadster gives the rear axle the thermal headroom the factory setup runs short of on a hard track day, as a matched left-and-right pair.

This is a rear-specific big brake kit, sized to work with the car’s nose-led balance rather than overwhelm it. With the straight-six sitting well forward and the semi-trailing-arm rear running light, the aim is consistent, predictable rear bite that supports rotation under trail-braking without snapping the back loose.

What this big brake kit does for your 1998-2002 BMW Z3 M-Coupe / Roadster

The most noticeable change is rear pedal consistency once the discs are hot. The hollow-vane disc design trims rotating and unsprung mass at the rear hubs, which helps the brakes recover between heavy applications and keeps the back of the car settled under repeated stops. Pad compound is your tuning lever: the Street compound suits quiet, low-dust road use, the Sport pad copes with fast road and the occasional track day, and the Racing compound holds bite through a full session of high-speed stops. On a chassis this eager to rotate, a rear that releases cleanly off the pedal lets you balance the car on the brakes instead of fighting it, and matching the rear compound to the front keeps that balance honest.

About the Hollow Rear Brake Kit

The kit pairs a two-piece floating rear disc, with a hollow-vane braking ring, with a fixed caliper and a choice of three pad compounds. The hollow-vane construction reduces rotating mass against a solid equivalent, lowering the heat the rear has to dump and helping the assembly cool between corners, while the floating bell lets the ring expand under heat without distorting. The calipers clamp a larger swept area than the standard rear arrangement, raising thermal capacity for repeated heavy braking. Street, Sport and Racing pads let you match the kit to anything from fast-road use to sustained circuit work without changing hardware. The caliper body is hollow-cast as standard, with a Hollow Racing upgrade available for serious track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Painted finishes run to Red, Yellow, Gold, Black or Anodized Black at no extra cost, with premium polished-forged and candy options and a custom Pantone choice, discs drilled or slotted at the same price, braided lines included, and a centre-bell upgrade in two-tone anodized colours or titanium, so the rear corners can be matched to the rest of the car.

Fitment for the BMW Z3 M-Coupe / Roadster (1998-2002)

This rear kit is sized for the M-Coupe and M-Roadster built from 1998 to 2002, as a left-and-right pair. Both body styles share the same rear hub and brake architecture, so the kit suits the fixed-roof coupe and the soft-top roadster alike. Confirm your build year falls inside the 1998-2002 span before configuring.
