Caliper render for this kit:
The 982 GT4’s 4.0-litre naturally aspirated flat-six was lifted directly from the 911 GT3 engine family, and it has no interest in being driven gently. On circuit, those 420 horses ask hard questions of the braking system, and while Porsche’s factory front setup is genuinely capable, sustained lap sessions at a Nürburgring day or a Silverstone track day will push any factory compound toward its thermal limit. The XYZ Racing front big brake kit is built specifically for the demands that come with owning one of these.
This is a front-axle kit: a matched pair of front calipers and two-piece floating discs for the left and right corners, supplied with braided lines for a firmer, more consistent pedal. It covers the Cayman 718 GT4 across its full production run from 2019 to 2026, with three pad compounds and a full range of caliper finishes to spec when you order.
What this brake kit does for your 2019-2026 Porsche CAYMAN 718 (982) GT4
The GT4’s near-perfect mid-engine weight distribution means brake balance is already well-sorted from the factory. What this kit addresses is sustained performance under heat load. The hollow-vane disc moves air through the rotor and pulls thermal energy away from the pad contact surface faster than a solid cast equivalent, keeping fluid temperatures in check across a full track-day programme, where fade typically builds on the third or fourth heavy stop sequence rather than the first.
The two-piece floating disc and braided lines work together to keep pedal travel short and consistent deep into a session. The Racing compound transforms front-end braking confidence at sustained track temperatures, giving the mid-engine balance something it can lean on through repeated hard braking zones. The Sport compound suits owners running the GT4 hard on the road with occasional track use, and the Street compound keeps things quiet and low-dust between events.
About the Hollow front brake kit
The caliper is a hollow-body design as standard, which keeps rotating and unsprung mass down without compromising clamping rigidity. For owners doing serious circuit mileage, the optional Hollow Racing upgrade deletes the dust cover, is rated to 1000C and carries a two-year warranty for repeated high-temperature use.
Three pad compounds cover the full spread of use. Street is the quiet, low-dust road default. Sport adds bite and heat range for fast road plus occasional track. Racing is a dedicated track compound formulated for the elevated and sustained temperatures lap sessions generate. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost. A Custom Color in any Pantone is available, and premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) sit above those for owners who want the hardware to be a feature in its own right.
Fitment for the Porsche CAYMAN 718 (982) GT4 (2019-2026)
This kit is built for the 718 Cayman GT4 on the 982 platform, spanning the production window from 2019 through 2026. The 982 GT4 is a single clear chassis generation. Confirm your car’s chassis code before ordering, as the earlier 981 Cayman GT4 (2015-2016) uses a different specification and is not covered by this kit.

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.
