XYZ Racing Hollow Rear Brake Kit — Bmw 3 SERIES F 34 3 GT (OE185) (2012-2018)

The F34 Gran Turismo is the heaviest 3 Series of its generation, and that mass tells most at the rear axle, where the extended liftback body and long 2,920mm wheelbase load the back discs hard under repeated braking. The XYZ Racing Hollow Rear Brake Kit targets exactly that: more thermal headroom and a firmer, more consistent pedal for a car BMW built for relaxed touring rather than circuit work.

It is a rear-axle upgrade for the 2012-2018 Bmw 3 Series F 34 3 GT, swapping the OE185 setup for a lighter two-piece floating disc and a fixed caliper that resists the fade a heavy GT generates on a fast B-road or a long downhill run. You choose the pad compound and caliper finish to match how you actually drive it.

What this rear big brake kit does for your 2012-2018 Bmw 3 Series F 34 3 GT

Step on the brakes and the bite arrives sooner and holds steady as the discs heat. The two-piece floating disc strips rotating and unsprung mass from the rear axle, so the back of the GT settles faster over crests and the suspension has less inertia to fight. The fixed caliper flexes less than the sliding OE unit, which tightens pedal feel and keeps the bite point in one place through a long descent. Pad choice does the rest: the Street compound suits a daily that sees the odd spirited run, Sport adds bite for harder fast-road work, and the Racing compound gives a heavy GT the heat tolerance for back-to-back hard stops without the pedal going long.

About the Hollow rear brake kit

The XYZ Racing Hollow kit replaces the rear discs and calipers as a matched pair rather than bolting a bigger pad onto tired hardware. The two-piece floating disc is the centrepiece: internal sections are cut away to drop weight while preserving swept area and the venting the kit needs to shed heat under the mass of a full-size GT body. The caliper is a fixed multi-piston design with a hollow body as standard, and a Hollow Racing upgrade is available for serious track use, no dust cover, rated to 1000C and carrying a two-year warranty. The included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no cost, with a Custom Color in any Pantone available, clamping the pad evenly across its face for predictable response. Three pad compounds, Street, Sport and Racing, set the kit’s character, from quiet road manners to repeat-stop resilience. Discs come drilled or slotted at the same price, with titanium or two-tone anodized centre bells selectable at checkout. Everything is sized around the rear axle of the F34 GT, so clamping load and geometry suit the car.
