XYZ Racing Hollow Front Brake Kit — Porsche 991 GT2 RS (2016-2019)

The 991 GT2 RS’s rear-biased weight distribution shifts forward aggressively under braking, loading the front axle with a deceleration force that the chassis’s short wheelbase translates into sharp pitch behaviour. Repeated braking zones on circuit expose thermal limits quickly; the front discs are working against a car that, by architecture, asks a great deal of them on the approach to any corner.

This XYZ Racing front big brake kit brings a steel disc solution to the 991 GT2 RS (2016-2019), built to manage heat between zones rather than accumulate it. Three pad compounds, Street, Sport, and Racing, let you specify the friction characteristic for the conditions you are actually operating in. 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 2016-2019 Porsche 991 GT2 RS

The hollow-vane disc drives airflow through the rotor body, extracting heat that would otherwise build to the point of fade on a car this powerful running sustained circuit sessions. On a rear-engined, rear-wheel-drive platform like the GT2 RS, front brake consistency matters throughout a stint; fade that shifts your braking reference mid-approach disrupts the balance at precisely the moment you need it most. The Racing compound holds friction at the sustained temperatures generated by repeated hard stops; Sport keeps initial bite progressive from cold without sacrificing response on the open road; Street is the quiet, low-dust compound for road miles between track outings. Two-piece floating disc construction lets the friction ring expand and cool independently of the bell, which is what keeps that reference fixed lap after lap.

About the Hollow Front Brake Kit

The hollow designation refers to the internal vane structure of the disc, a construction that maximises heat extraction by channelling airflow through the rotor rather than relying on thermal mass alone. That approach keeps disc operating temperatures more consistent across a session, which matters when the GT2 RS’s 700-odd brake horsepower is loaded repeatedly into the same braking zone. Three compounds span the range: Street suits owners wanting a step up on OE without a track-specific spec; Sport targets fast-road use and occasional circuit days where cold bite still matters; Racing is the track compound for sustained high-temperature operation where fade resistance takes priority. 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. A Custom Color in any Pantone is available, plus 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 GT2 RS (2016-2019)

This is a front axle application for the Porsche 991 GT2 RS, covering the full production run from 2016 to 2019. Verify wheel clearances against your specific rim specification before ordering; the GT2 RS came with centre-lock wheels as standard, and spoke geometry on aftermarket alternatives varies considerably across suppliers.
