EBC’s acclaimed two-piece, fully-floating front and rear rotors now available for ‘Turbo’ and ‘Turbo S’ 991-generation 911s, as well as the 981 Cayman GT4

Porsche Two-Piece Fully-Floating Disc

The motorsport product arm of EBC Brakes – EBC Brakes Racing – is pleased to announce new additions to its two-piece fully-floating brake disc range: the 380x34mm SG2F016 (front) and 380x30mm SG2F012 (rear) discs for ‘Turbo’ and ‘Turbo S’ 991-generation Porsche 911s and the 981 Cayman GT4.

The discs use a novel two-piece hub design which reduces unsprung rotational weight that has such a profound impact on vehicle driving dynamics.

Ideal for regular track-goers and cars boasting high levels of tune.

Application List

SG2F016 discs will fit the front axle of the following vehicles:

Porsche 911 (991) (Cast Iron Disc Only) 3.8 Twin Turbo 520 2013-2015
Porsche 911 (991) (Cast Iron Disc Only) 3.8 Twin Turbo S 560 2013-2015
Porsche 911 (991/2) (Cast Iron Disc Only) 3.8 Twin Turbo 540 2015-2020
Porsche 911 (991/2) (Cast Iron Disc Only) 3.8 Twin Turbo S 580 2015-2020
Porsche Cayman GT4 (Cast Iron Disc Only) 3.8 385 2015-2016

SG2F012 discs will fit the rear axle of the above vehicles.


Key Features

  • EBC’s two-piece fully-floating 380x34mm (front) and 380x30mm (rear) discs are a simple bolt-on upgrade that seamlessly replace the original ‘pin-drive’ brake disc without vehicle modification.
  • Unlike the stock pin-drive discs which do not float, EBC’s SG2F fully-floating rotor allows the outer cast-iron friction ring to expand freely with temperature, totally eliminating disc ‘warping’.
  • Where the vehicle has a 2-piece pin-drive brake rotor as original equipment, EBC’s SG2F 2-piece rotor upgrade seamlessly replaces the pin-drive rotor with a true fully-floating 2-piece rotor, whilst requiring no vehicle modifications.
  • Discs are grooved unlike the original rotors which are perforated. This allows the pad to vent without the holes becoming epicentres for disc cracking.
  • Race-derived G3500 grade high-carbon cast-iron is used for the friction rings. This high-quality metallurgy possesses greater crack resistance and an increased ability to conduct and then radiate heat.
  • Aluminium bells are machined from aerospace-grade aluminium and then hard anodised for longevity, whereas the stock brake rotors use uncoated cast aluminium bells.
  • Cast-iron friction rings feature 48-curved vanes and are handed for each side of the vehicle. This significantly improves the brake discs’ ability to radiate heat, increasing brake system endurance and prolonging the onset of brake fade.
  • Bobbins are machined from stainless steel which cannot rust, ensuring the disc continues to float freely throughout its entire life cycle on the vehicle, even on road cars.
  • Spring clips ensure totally silent operation and eliminate off-brake disc rattle.
  • Friction rings can be replaced individually after they have become worn, allowing the aluminium bell and stainless steel bobbins to be re-used, leading to lower long-term operating costs.
