Porsche 992 GT3 / GT4 RS 380x30mm Rear Brake Discs for track-focused road cars. Two-piece floating brake disc construction helps manage heat, reduce fade, and improve braking consistency under repeated hard use.
Made to order. Production and dispatch usually take about 30 days from order confirmation.
Brake disc measurement: 380×30mm rear, matching the shared 992 GT3 / 718 GT4 RS factory motorsport-derived rear brake package.
Two-piece floating construction: an aluminium bell decoupled from a high-carbon cast iron friction ring, cutting unsprung weight and letting the disc expand under heat without warping.
Built for the GT3/GT4 RS’s typical use case: fast-road and track-day driving, where the factory rear disc helps manage braking bias under repeated hard stops from high speed on track.
Pairs with OEM-fitment 992 GT3 / 718 GT4 RS rear calipers, no bracket or caliper swap needed on a stock car.
Fits the Porsche 992 GT3 and 718 GT4 RS with the factory rear brake package, since both share the motorsport-derived brake architecture. Always confirm your exact caliper part number and disc bell diameter before ordering, and we want to get this right the first time. Not sure which version you have?
