EBC two-piece floating SG racing rear rotors for 2016–2020 Porsche 911 (991/992) GT3 replace one-piece OEM discs with a floating assembly that pairs a cast friction ring to a reusable hub. The conversion is designed to work with OE calipers and pads, reducing unsprung mass and allowing the outer ring to be replaced when worn. This approach improves handling response and lowers lifetime servicing costs for track-focused use.
