XYZ Racing Hollow Rear Brake Kit — Bmw 6 SERIES F 13 (2011-2017)

On a car as heavy as the F13 6 Series coupe, the rear axle does quieter work than the front, but it sets the balance of everything that happens under braking. Push a near-1.9-tonne grand tourer hard into a downhill braking zone and a tired rear end is what unsettles it – the nose dives, the back goes light, and the stability control starts trimming your line for you. The XYZ Racing Hollow Rear Brake Kit for the Bmw 6 Series F 13 exists to keep that rear axle composed.

This is a rear-position kit – a pair of left and right rear calipers and two-piece floating discs – that gives the back of the car real, repeatable bite. It is the fast-road and track-day answer for owners who have already noticed their standard rear brakes going soft after a few committed stops.

What this big brake kit does for your 2011-2017 Bmw 6 Series F 13

The first thing you feel is brake balance you can trust. With more consistent clamping at the rear and braided lines firming the pedal, the F13 settles under trail-braking instead of leaning entirely on the fronts, so you can carry speed deeper without the back stepping wide. The two-piece floating disc design sheds unsprung and rotational mass, which sharpens how quickly the rear wheels respond to inputs. Three pad compounds – Street, Sport and Racing – let you match the rear bite to how you actually use the car, from motorway miles on the Street pad, through fast road and occasional track days on Sport, to repeat lap sessions on Racing. And because the calipers come painted at no extra cost in Red, Yellow, Gold, Black or Anodized Black, the upgrade reads as intentional through the wheel spokes rather than an afterthought.

About the Hollow rear brake kit

The kit is built around two-piece floating discs: the friction ring is lightened to cut weight and aid cooling without giving up the swept area a heavy GT needs, carried on an alloy bell and available drilled or slotted at the same price. Larger rear rotors and a fixed multi-piston caliper replace the sliding factory setup, raising thermal capacity so the rear pads hold their friction level through sustained use instead of glazing. 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. The Street compound suits road driving, the Sport compound steps up initial bite and heat tolerance for fast road and occasional track days, and the Racing compound is built for circuit temperatures. Beyond the included painted finishes, the caliper can be specified in Custom Color in any Pantone for £150, premium polished-forged Titanium, Polished Gold and Polished Silver, or candy Teal, Blue, Red and Orange, with centre bells upgradeable to two-tone anodized in five colours or to titanium.
