XYZ Racing Hollow Rear Brake Kit — Bmw 5 SERIES E 34 525 (1988-1996)

The E34 525 carries its mass like the executive express it was built to be: a long, rear-wheel-drive saloon tuned for autobahn calm rather than repeat heavy stops. That bias shows up at the rear axle first, where the standard discs heat-soak and the pedal goes long after a few committed stops down a fast B-road. The XYZ Racing Hollow Rear Brake Kit for the BMW 5 Series E34 525 is aimed squarely at that end of the car.

This is a rear-axle package, a pair of left and right rear calipers and matched discs sized to rebalance braking on a saloon that loads real weight over its back wheels under deceleration. The two-piece floating disc design sheds rotational mass and helps the assembly carry heat away between stops, so the rear stays consistent rather than turning soft when you lean on it.

What this brake kit does for your 1988-1996 Bmw 5 Series E 34 525

Fitted to the rear axle, the kit firms up a pedal that on a standard 525 tends to soften as the original discs cook. The two-piece floating rotor lowers rotational and unsprung mass at the back, which the comfort-sprung E34 chassis feels as slightly sharper response and steadier composure over mid-corner bumps. Pad choice sets the character: Street keeps quiet, low-dust daily manners, Sport adds bite for fast-road driving with occasional track use, and Racing holds up when a heavy saloon is asked for repeated hard stops. The net result is a rear axle that resists fade and keeps the car’s brake balance front and rear honest under load.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is XYZ Racing’s rear-axle big brake package, a pair of left and right rear calipers built around a two-piece floating disc that trades solid material for lower rotational weight without surrendering swept area. Less mass spinning at the wheel means heat clears more readily between applications, which is the core reason a rear setup like this stays consistent where a standard disc gives up. The caliper body is hollow as standard, with a Hollow Racing upgrade for serious track use, no dust cover, rated to 1000C and backed by a two-year warranty. Three pad compounds are offered, Street, Sport and Racing, so the kit can be specified for a road car, a fast-road 525, or a saloon that sees occasional track or hillclimb use. The included painted caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no cost, with a Custom Color in any Pantone available so the hardware behind the rear wheels can be matched to the car. Discs come drilled or slotted at the same price, with centre-bell upgrades selectable at checkout. As a rear kit it is built to complement a front brake upgrade or sit alongside the factory fronts, restoring balance to a chassis whose rear braking was always the limiting factor.
