Fits Porsche 992 GT3 (2021-2026)

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 Front Brake Kit — Porsche 992 GT3 (2021-2026) — 400 mm
400 mm

The 992 GT3 arrives with a braking system calibrated for genuine circuit use from the factory; Porsche’s grasp of rear-weight-biased dynamics means the standard steel-brake setup is far from an afterthought. The issue is not peak stopping power, it is thermal endurance under sustained circuit use. This XYZ Racing front big brake kit targets that window: repeated heavy braking zones, back-to-back sessions, a Nordschleife lap pushed properly, or any scenario where heat soak eventually erodes what the pedal can do.

The 992 generation brought rear-axle steering to the GT3 as standard, transforming corner entry in a way that changes what the front brakes need to deliver. Harder, later braking points into fast corners are achievable in a way the 991 couldn’t match, and that places greater demand on the front brakes, both in temperature cycling and outright consistency. The kit fits the front axle as a matched left and right pair with two-piece floating discs.

What this brake kit does for your 2021-2026 Porsche 992 GT3

The hollow-vane disc increases the rotor’s ability to dissipate heat through its internal geometry, drawing air through the disc faces during rotation and extending the point at which fade begins to compromise pedal feel. For a car regularly used at the limit, track days, timed sessions, fast-road driving in mountainous terrain, that thermal window is the meaningful difference. Three pad compounds, Street, Sport, and Racing, let the friction spec match actual use: a 992 GT3 that commutes during the week and circuits at the weekend needs a different profile than one that only leaves the garage for trackday events. Two-piece floating disc construction lets the friction ring expand and cool independently of the bell.

About the Hollow Big Brake Kit

The Hollow series takes its name from the internal geometry of the disc: rather than a conventional vented rotor where vanes simply separate the two friction faces, the hollow construction actively channels airflow through the disc during rotation, moving heat out of the material between braking events rather than allowing it to accumulate. The front kit is engineered around the 992 GT3’s double-wishbone front axle, the suspension layout that distinguishes the GT3 from the MacPherson-strut configuration used across the wider 992 range, so clearances and mounting geometry are matched to the chassis as built. Street is the quiet, low-dust road compound; Sport steps up bite and operating temperature for fast-road and repeated hard use; Racing is the track compound for full heat-cycle consistency. 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. 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, with a Custom Color in any Pantone, premium polished-forged finishes (Titanium, Polished Gold, Polished Silver), and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange).

Fitment for the Porsche 992 GT3 (2021-2026)

This front kit covers the Porsche 992 GT3 from the 2021 model year through to 2026, engineered around the GT3’s double-wishbone front suspension geometry rather than the standard 992 platform. Cars fitted with the factory Porsche Ceramic Composite Brake option use different caliper positions and mounting dimensions from the steel-braked specification; if your car has PCCB fitted, confirm compatibility before ordering.

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.
