Fits Bmw 2 SERIES F22 235I (OE161) (2014-2026)

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 2 SERIES F22 235I (OE161) (2014-2026) — 330 mm
330 mm

The F22 235i puts an N55-fed straight-six through the rear wheels of a short, eager coupe, and that layout loads the rear axle the instant you brake into a corner. The XYZ Racing rear brake kit goes after the part of the car most owners ignore: the rear discs that quietly run out of thermal headroom on a track day while all the attention is on the fronts.

This is a rear-axle package built for repeated heavy stops rather than one hero lap. With three pad compounds and a two-piece floating disc design, it lets you set the rear braking character of the 2 Series F22 235I to suit how you actually drive, from fast road to full circuit sessions.

What this big brake kit does for your 2014-2026 Bmw 2 Series F22 235I (OE161)

Fit it and the first thing you feel is balance. The standard rear setup on the F22 235i tends to lose its bite as heat builds, and a larger ventilated rear package holds a more consistent pedal across a session, which steadies the car under trail-braking when the rear is already light. The two-piece floating disc trims rotating and unsprung mass at each rear corner, so the rear suspension settles faster over kerbs and broken tarmac. Run the Racing compound for circuit work, the Sport compound for fast-road bite with the odd track day, or the Street compound for strong cold bite and low dust on the road. A wide range of caliper colours, from Red, Yellow, Gold, Black and Anodized Black to a custom Pantone option, means the result looks deliberate through the spokes.

About the Rear Brake Kit

The rear brake kit is XYZ Racing’s response to rear-axle fade on fast road and track-focused cars, supplied as a matched pair of left and right rear calipers and discs. Its defining feature is the two-piece floating disc, which uses a hollow-vane construction to remove material from the disc and cut rotating mass while keeping the swept area you need to shed heat; it comes drilled or slotted at the same price, on braided lines. It is supplied as a complete rear package matched to the 2 Series F22 235I, so the caliper, disc and mounting hardware are specified to work together rather than assembled from mismatched parts. The forged caliper is hollow-body as standard, with an optional Hollow Racing upgrade (no dust cover, 1000C rated, two-year warranty) for hard lapping. Three pad compounds, Street, Sport and Racing, span daily commuting through to lapping. Included painted caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for a small upcharge, plus premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy (Candy Teal, Candy Blue, Candy Red, Candy Orange) finishes, and two-tone centre bells in five anodized colours or titanium at checkout. The brief is straightforward: rear braking that stays consistent through repeated heavy stops.

Fitment for the Bmw 2 Series F22 235I (OE161) (2014-2026)

This kit is specified for the Bmw 2 Series F22 235I (OE161) across the 2014 to 2026 span of the F22 chassis in 235i form. It is a rear-position kit, so it complements a front upgrade rather than replacing one. Confirm your car matches the F22 235i OE161 reference before configuring, as fitment is tied to that exact chassis and brake specification.

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.
