XYZ Racing Hollow Rear Brake Kit — Bmw 5 SERIES E 60 550 (2003-2010)

The E60 550’s N62 V8 puts close to two tonnes of executive saloon into every braking zone, and on this chassis the rear axle carries more of that load than most owners expect. Heavy over the nose and genuinely fast across a derestricted motorway, the 550i leans on its rear brakes to manage weight transfer and keep the back end settled under hard, repeated stops.

The XYZ Racing Hollow Rear Brake Kit is built for that exact job. Its two-piece floating discs trim rotating and unsprung mass at the rear corners while adding the thermal headroom a 360bhp saloon needs when the pace stays high. This is the rear half of a serious braking upgrade for the 2003-2010 5 Series E 60 550 – a pair of left and right rear calipers and discs, not a four-corner set.

What this brake kit does for your 2003-2010 Bmw 5 Series E 60 550

Fit it and the first thing you feel is a firmer, more progressive pedal under big stops from speed, helped by the braided lines. The vented two-piece discs shed heat faster than the standard cast items, so braking stays consistent through a fast cross-country run instead of going soft after the third or fourth heavy application. Less rotating mass at the rear hubs also takes a little inertia out of the back axle, sharpening how the car responds to throttle and direction changes. With three pad compounds on offer – Street, Sport and Racing – you can match bite and temperature range to how you actually use the 550, from refined daily commuting on the Street pad, through fast-road work on Sport, to circuit heat on the Racing compound.

About the Hollow rear brake kit

XYZ Racing’s kit is built around two-piece floating discs: a lighter rotor that removes material without giving up swept area, cutting unsprung and rotating weight at each rear wheel. Those discs pair with XYZ calipers and a choice of three pad compounds. Street is the quiet road-and-cold-bite option; Sport steps up friction and fade resistance for spirited driving; Racing targets sustained high-temperature use where pedal consistency matters most. The caliper body is hollow-cast as standard, with a Hollow Racing upgrade for serious track use that drops the dust cover for a 1000C rating and a two-year warranty. Discs can be drilled or slotted at the same price, and centre bells upgraded to two-tone anodized in five colours or to titanium. Calipers can be finished at no extra cost in Red, Yellow, Gold, Black or Anodized Black, with Custom Color in any Pantone for £150, premium polished-forged Titanium, Polished Gold and Polished Silver, and candy Teal, Blue, Red and Orange. It is engineered as a rear-axle kit, sized to balance a front upgrade rather than carry the braking job on its own.
