Fits Bmw 3 SERIES F 30 328I (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.

Painted — includedTell us the exact Pantone (PMS) code you want the calipers painted.Polished forgedCandy
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 328I (OE161) (2012-2018) — 330 mm
330 mm

The F30-generation 328i carries a turbocharged 2.0-litre four ahead of the front axle and leans on a front-biased brake balance, which leaves the rear doing less of the work than it could under hard stops. This XYZ Racing rear brake kit for the Bmw 3 Series F 30 328I (OE161) puts a pair of larger, lighter two-piece floating discs and a pair of fixed calipers on the rear axle to bring that balance back.

Built around a hollow-vane disc that sheds rotating and unsprung mass, the kit suits F30 owners who want the rear axle to contribute properly on a quick B-road or a track day without making the daily drive coarse. The pad compound is your call when you order, from a quiet Street pad through to a full Racing compound.

What this rear brake kit does for your 2012-2018 Bmw 3 Series F 30 328I (OE161)

With more swept disc area at the back than the standard item, the rear axle of your F30 328i takes a bigger share of the deceleration, which steadies the car on corner entry and reins in the nose-dive a heavy front end tends to produce. The lightweight disc design trims rotating and unsprung mass, so the rear wheels track bumps better and the brake answers the pedal more crisply. Pick the Racing pad compound and you get a bite that survives repeated heavy stops; choose the Street pad and it stays clean, quiet and low-dust on the commute, with Sport in between for fast-road work. With a full range of caliper finishes on offer, the rear of the car also reads properly through an open-spoke wheel.

About the rear brake kit

The kit centres on a two-piece floating disc, which uses a hollowed internal vane structure to cut rotating mass while keeping thermal capacity intact, and a friction ring that floats on its alloy bell to stay flat under heat rather than warping. It is a rear-axle-specific kit for the F30 328i, referenced to the OE161 code so the disc diameter and hat geometry sit correctly on the standard rear hub and wheel package, with the disc face available drilled or slotted at the same price. The caliper comes in painted Red, Yellow, Gold, Black and Anodized Black at no extra cost, with premium polished-forged, candy and Custom Pantone options, so you can match or contrast the car, and it is hollow-cast as standard with a Hollow Racing upgrade for serious track use. Pad compound is selectable across three grades: a Street pad for quiet, low-dust manners, a Sport pad for harder fast-road use, and a Racing pad for sustained track work. The upshot is a rear brake that scales to how you actually drive the 3 Series rather than imposing one fixed character.

Fitment for the Bmw 3 Series F 30 328I (OE161) (2012-2018)

This kit fits the Bmw 3 Series F 30 328I (OE161) across the 2012 to 2018 build span, covering the turbocharged 328i variant of the sixth-generation 3 Series saloon. It is a rear-axle fitment tied to the OE161 disc reference, so confirm your car carries that rear brake specification before ordering. Caliper colour, disc style and pad compound are all chosen when you order.

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.
