XYZ Racing Hollow Rear Brake Kit — Bmw 3 SERIES F 30 335I (OE185) (2012-2018)

The F30 335i is the heaviest, most GT-leaning 3 Series BMW had built to that point, and its N55 turbocharged straight-six hides real pace behind a relaxed demeanour. That combination, 300-plus bhp and the better part of 1,600kg, pushes more work through the rear axle than the chassis lets on, and the factory rear discs start to go long once you use the car in anger.

This is a rear big brake kit for owners running repeat track sessions or hard fast-road work who want the back of the 335i to keep doing its job under sustained braking. Two-piece floating discs shed weight and vent heat, and a choice of pad compound lets you match the kit to how you actually drive.

What this brake kit does for your 2012-2018 Bmw 3 Series F 30 335I (oe185)

Fit this rear kit and the first thing you feel is a back axle that stays composed when you trail-brake the 335i into a corner. The two-piece discs run cooler and lighter than the standard items, so pedal feel holds up across a session instead of fading after a handful of hard stops. Trimming rotating mass at each rear corner also takes a bite out of unsprung weight, helping the rear dampers keep the tyres planted over kerbs and broken surfaces. The three pad compounds, Street, Sport and Racing, let you set bite and temperature range for a daily F30, a fast-road car or a dedicated track build. The included painted caliper colours, Red, Yellow, Gold, Black and Anodized Black, come at no cost, with a Custom Color in any Pantone available to keep the hardware looking deliberate behind an open wheel.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is built around a pair of left and right rear calipers and matched two-piece floating discs, sized to draw heat out of the friction surface and vent the gases that build between pad and disc under repeated braking. That matters on a turbocharged 335i, which carries far more speed into a braking zone than its road manners suggest. The caliper body is hollow as standard, with a Hollow Racing upgrade available for serious track use, no dust cover, rated to 1000C and backed by a two-year warranty. Each kit pairs the discs with a pad of your choosing: Street for quiet daily road use, Sport for harder fast-road driving with the odd track day, or Racing for circuit temperatures. The discs come drilled or slotted at the same price, and centre-bell upgrades in titanium or two-tone anodized finishes are selectable at checkout. Because this is a rear-specific kit, it works alongside the car’s existing front brakes rather than replacing the whole system, concentrating the upgrade where the F30’s rear-axle heat builds.

This kit is cut for the Bmw 3 Series F 30 335i built between 2012 and 2018, the rear-drive turbocharged six-cylinder version of BMW’s sixth-generation 3 Series. The OE185 designation in the listing ties the kit to your car’s factory rear brake specification, so the discs and caliper bracket suit the F30 335i’s rear hubs. Confirm your build year falls inside the 2012 to 2018 span before ordering.
