Fits Porsche 991 CARRERA-2/S/GTS (2WD) (142) (2012-2019)

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 Front Brake Kit — Porsche 991 CARRERA-2/S/GTS (2WD) (142) (2012-2019) — 356 mm
356 mm

The 991’s rear-biased weight distribution is central to the 911’s driving character, but it creates an asymmetric demand at the front axle under hard braking. Weight transfers forward aggressively as speed scrubs off, and on a circuit or a committed B-road the front discs absorb heat and load disproportionate to their static share of the car. Stock Carrera, Carrera S, and GTS front brakes handle routine use without complaint, but there is a ceiling: repeated hard stops accumulate temperature, the pedal becomes less precise, and the front-end confidence that defines the 991 starts to erode before the session ends.

The XYZ Racing front big brake kit upgrades the 2012-2019 Porsche 991 CARRERA-2/S/GTS (2WD) front axle for exactly that kind of use. Three pad compounds, Street, Sport, and Racing, let it be configured as a daily-driver system, a fast-road upgrade, or a dedicated track setup. The kit fits the front axle as a matched left and right pair.

What this brake kit does for your 2012-2019 Porsche 991 CARRERA-2/S/GTS (2WD) (142)

The hollow-vane disc reduces rotating mass compared with a standard vented equivalent, which sharpens the 991’s already communicative front-end feel through the steering. Greater swept area over the OEM disc improves thermal management across consecutive hard braking events, where the 991.2’s turbocharged flat-six, with its broader torque spread, tends to generate heavier and more frequent brake loading than the naturally aspirated 991.1 ever did. The three-stage compound range lets owners match the setup to actual use: road miles on Street, spirited fast-road driving on Sport, full circuit sessions on Racing. Two-piece floating disc construction lets the friction ring expand and cool independently of the bell, sustaining bite across longer sessions.

About the Hollow Front Big Brake Kit

The hollow disc refers to the rotor’s internal architecture: airflow channels cast through the iron that draw cooling air through the disc body rather than relying solely on surface flow. For the 991’s front axle, handling the bulk of deceleration from motorway speeds and circuit braking markers, this sustains consistent bite and pedal feel across longer sessions than a conventional vented disc allows. The big brake format pairs those discs with a caliper carrying greater piston area than the OEM unit, spreading clamping force more evenly across the pad face. The forged caliper is hollow-bodied as standard, with an optional Hollow Racing upgrade for serious track use, rated to 1000C with no dust cover and a two-year warranty. Street, Sport, and Racing compounds address the full operating range from cold commutes to sustained circuit use. Discs come drilled or slotted at the same price.

Included painted caliper colours are Red, Yellow, Gold, Black, and Anodized Black at no extra cost. A Custom Color in any Pantone is available, alongside premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange).

Fitment for the Porsche 991 CARRERA-2/S/GTS (2WD) (142) (2012-2019)

This front brake kit is designed for all two-wheel-drive 991 Carrera variants in the 142 body code, Carrera, Carrera S, and GTS, from 2012 to 2019. The fitment spans both the 991.1 generation with its naturally aspirated 3.4 and 3.8-litre flat-six engines and the 991.2 facelift from 2016, where the turbocharged 3.0-litre’s broader torque output places higher sustained thermal demands on the front braking system.

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 286–380mm (front). 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.
