XYZ Racing Hollow Rear Brake Kit — Bmw 3 SERIES F 30 335I (OE161) (2012-2018)

The F30 335i carries real mass over its rear axle, and once the N55’s torque is loading a set of sticky tyres out of a slow corner, the standard rear discs soak up heat faster than most owners expect on a long track session. The XYZ Racing Hollow Rear Big Brake Kit for the Bmw 3 Series F 30 335I (OE161) goes after exactly that weakness, adding rear thermal capacity and pedal consistency to a 2012-2018 saloon that is heavier and quicker than its tidy four-door shape lets on.

Two-piece floating discs sit at the centre of this kit, cutting rotating and unsprung mass at the rear where the F30 chassis benefits most. With Street, Sport and Racing pad compounds offered, the same rear hardware can be matched to a fast-road 335i or one that runs repeat circuit laps.

What this big brake kit does for your 2012-2018 Bmw 3 Series F 30 335I (OE161)

Under hard braking the 335i shifts weight forward, but the rear axle still does meaningful work settling the car into a corner, and a heat-soaked rear disc shows up as a long, vague pedal. The two-piece discs in this kit shed rotating mass and vent heat more readily, so the rear stays composed deeper into a braking zone. Lower unsprung mass also lets the rear dampers track the road surface more cleanly, which the F30 rewards with a more planted rear end. Choose the Racing compound for sustained track temperatures, Sport for fast-road bite with occasional track use, or Street for a quiet, low-dust daily setup. The included painted caliper finishes run Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone shade available when you want the hardware to read a particular way behind the wheel.

About the Hollow Rear Brake Kit

This is a rear-axle kit, a pair of left and right rear calipers and matched two-piece floating discs that bolt to the F30’s rear hubs. The disc design removes rotating and unsprung weight without giving up swept area, so the rotor reaches working temperature sooner and sheds it faster between stops, which is where standard rear discs on a hard-driven 335i tend to struggle. The hollow-body caliper comes as standard, and a Hollow Racing upgrade is offered for serious circuit use, dropping the dust cover, rated to 1000C and carrying a two-year warranty. Three pad compounds let you set the friction package to how you actually drive: Street for quiet road manners, Sport for harder fast-road work, and Racing for circuit temperatures. Discs come drilled or slotted at the same price, and centre-bell upgrades in titanium or two-tone anodizing are selectable at checkout.
