XYZ Racing Hollow Rear Brake Kit — Bmw 5 SERIES E 39 525 (1995-2003)

The E39 525 carries close to a tonne and a half of refined executive saloon, and BMW sized its standard rear discs for smooth motorway stops rather than repeat heavy use. On a rear-wheel-drive car this size, the back axle does real work settling the chassis into a corner, and a tired rear setup shows up as a long, soft pedal once the discs get hot. The XYZ Racing Hollow Rear Brake Kit replaces that weak link.

Built around lightweight two-piece floating discs, this rear big brake kit, a pair of left and right rear calipers, cuts rotating and unsprung mass at the back of the E39 while adding the thermal headroom the standard rears lack. It is the upgrade for owners running fast-road miles or the occasional track day who want the rear axle to keep pulling its weight.

What this brake kit does for your 1995-2003 Bmw 5 Series E 39 525

After fitting, the first thing you notice is a firmer, more progressive pedal that holds its travel as the discs heat up. The two-piece floating disc design sheds weight at each rear corner, which sharpens turn-in response and takes load off the dampers over broken surfaces. With Racing pads fitted, the rear stays composed through repeated heavy stops where the factory setup would start to fade; Sport covers harder fast-road use, and Street keeps quiet, low-dust daily manners. The result is a more stable rear under trail-braking and a 525 that feels planted rather than nervous when you lean on it.

About the Hollow Rear Brake Kit

The kit pairs two-piece floating, mass-reduced discs with upgraded calipers to give the rear of the E39 consistent bite and better heat management than the standard rears. 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 for everyday low-dust road use, Sport for harder fast-road driving, and Racing for sustained track work. That spread lets you match the friction material to how you actually use the car rather than accepting a single compromise. 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 can sit discreetly behind the wheels or stand out as a visual statement. Discs come drilled or slotted at the same price, with centre-bell upgrades selectable at checkout. Everything is supplied as a bolt-on rear package for this chassis.
