Fits Infiniti Q50 2.0T (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 — Infiniti Q50 2.0T (2014-2026) — 330 mm
330 mm

The V37-generation Q50’s GT-leaning brief means most owners chase front-end stopping power and quietly forget that the rear axle does real work under hard, repeated braking. On a saloon this size, weight transfer loads the rears every time you trail toward an apex, and the factory rear discs glaze and lose bite long before the chassis gives up. The XYZ Racing rear brake kit for the Infiniti Q50 2.0T attacks that imbalance directly, adding rotor mass and consistent pad bite at the back of the car.

It is the rear half of a properly balanced upgrade for the 2014-2026 Q50 2.0T, a Mercedes-engined turbo-four saloon that carries plenty of mass over a long wheelbase. Specify it to stop the rears washing out on a fast B-road descent or a circuit session, and to keep the stability electronics working with the brakes rather than masking them.

What this brake kit does for your 2014-2026 Infiniti Q50 2.0T

Fit the Racing compound and the rear axle holds its bite through a full sequence of heavy stops, where the standard pad would already be glazing. The hollow-vane rotors shed heat faster and trim rotational mass at the rear, so the Q50 settles more quickly between braking zones. Run the Street compound alongside your existing fronts and you get firmer, more progressive pedal feel for daily work without the cold-bite penalty of a full race pad, with the Sport compound covering harder fast-road use in between. Because the kit shifts more braking duty to the rear, the car stays flatter and more composed under trail braking, with less nose-dive as the back wheels take their share. Caliper finish is yours to set, from the no-cost painted colours through to candy and polished-forged options.

About the Hollow Rear Brake Kit

XYZ Racing’s rear kit is a pair of larger two-piece floating discs and uprated calipers, with hollow-vane rotor castings that drop weight while opening cooling paths through the disc face. It comes with three pad compounds, Street, Sport and Racing, so the same hardware suits a daily Q50, a fast-road build or a car that sees regular track time. The Street pad stays clean and quiet for road use; the Sport compound lifts temperature tolerance and bite; the Racing compound is there for sustained high-load running where fade resistance is the priority. The caliper is hollow-body as standard, with an optional Hollow Racing upgrade for serious track use that loses the dust cover, is rated to 1000C and carries a two-year warranty. Painted finishes are no-cost in Red, Yellow, Gold, Black or Anodized Black; a Custom Color in any Pantone is £150, and premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy (Candy Teal, Candy Blue, Candy Red, Candy Orange) finishes are available too. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. The whole package is designed as a bolt-on rear pair rather than a one-size compromise, letting you match pad to use and finish to taste.

Fitment for the Infiniti Q50 2.0T (2014-2026)

This kit is the rear-axle fitment for the Infiniti Q50 2.0T across the 2014 to 2026 model years and fits as a pair of rear calipers and discs. It is specified for the 2.0T variant specifically, suiting the Mercedes-sourced turbo-four cars in that range. Confirm your exact build year before 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.
