380mm Race-Spec Rotors for a 991 Turbo

This black Porsche 911 Turbo (991) uses STOPFLEX long-fiber race-spec carbon ceramic rotors with blank friction faces. Photographs show AP Racing Pro5000R branding on one caliper and PORSCHE lettering on another; the supplied build specification identifies the discs at both axles.

• Front: STOPFLEX 380mm long-fiber race-spec carbon ceramic rotors.
• Rear: STOPFLEX 380mm long-fiber race-spec carbon ceramic rotors.

The reason to consider a race-oriented rotor is sustained thermal duty. STOPFLEX describes continuous carbon strands as carrying load across the rotor for higher strength and thermal durability. Its Motorsport option is intended for competition-focused use with an appropriate pad, fluid, cooling and warm-up strategy. The purchase therefore extends beyond a disc: the supporting system needs to suit that duty as well.

That makes the choice worth comparing with a Street specification if your 911 mainly covers road miles. The highest-duty option is not the default road recommendation, and cold initial response still deserves consideration. The race-spec description here identifies the supplied component; it does not establish that this car has completed track testing.

One photographed rotor hat is marked 380x36mm. Keep that measurement with the particular rotor record: equal front and rear diameters do not establish identical thickness or hat geometry.

Match the Calipers to the Rotor Specification

The 991 Turbo carbon ceramic rotor listing includes a separate review route for AP Racing and other aftermarket calipers. Supply exact caliper models, pad shapes, rotor measurements and wheel details before specifying a similar package.
