Fits Bmw 3 SERIES F 30 316I (OE161) (2012-2018)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Rear Brake Kit — Bmw 3 SERIES F 30 316I (OE161) (2012-2018) — 330 mm
330 mm

The F30 316i left BMW’s production line with rear brakes scaled to a 136bhp entry saloon, not to the loads a modified or hard-driven car actually puts through the back axle. The XYZ Racing rear brake kit for the BMW 3 Series F30 316i (OE161) tackles that gap directly, replacing the standard rear setup with a pair of larger two-piece floating discs and a pair of fixed calipers that hold up where the factory parts start to soften.

Rear braking on the F30 is as much about balance as outright stopping force. With more consistent clamping at the rear, this kit helps settle the chassis under trail braking and steadies that slightly nervous rear end the long-wheelbase saloon can show when you brake deep into a corner on a track day.

What this brake kit does for your 2012-2018 BMW 3 Series F30 316i

After fitting, the first thing you feel is a firmer, more repeatable pedal that does not fade as the rotors heat through a session. The larger rear disc adds thermal capacity, so the back brakes stop overheating and dragging the balance forward. You choose the bite to suit how you drive: Street pads for quiet, low-dust daily running, Sport pads for fast-road work, and Racing pads when the 316i sees real circuit time. The fixed caliper also tidies up pedal feel, cutting the flex and knock-back that the sliding factory caliper develops with age.

About the rear brake kit

The two-piece floating disc strips rotating and unsprung mass out of the rear corner without losing swept area, and the friction ring floats on its alloy bell so it stays flat as it heats rather than warping. The disc face is available drilled or slotted at the same price. The kit pairs that disc with a fixed multi-piston caliper and a choice of three pad compounds, Street, Sport and Racing, so one hardware platform covers everything from commuting to lapping. Calipers are finished in your pick of painted Red, Yellow, Gold, Black and Anodized Black at no extra cost, with premium polished-forged, candy and Custom Pantone options, so the look behind the wheel matches the build. The caliper is hollow-cast as standard, with a Hollow Racing upgrade for serious track use. It is engineered as a bolt-on upgrade for the rear axle, designed to raise heat tolerance and pedal consistency on a chassis whose standard rear brakes were specified for economy, not abuse.

Fitment for the BMW 3 Series F30 316i (2012-2018)

Choosing your spec

Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.

Brake pads — Street, Sport or Racing

Every kit ships with a full set of high-performance pads; the compound is your call.

Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.

Caliper grade — Hollow vs Hollow Racing

Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.

Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 330–356mm (rear). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish

Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).

Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.

Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).

Centre bells

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
