Craftsmanship meets fine materials in our highest performing rotor to date. EBC Racing BMW M2 F87 M3 F80 M4 F82 F83 2 Piece Rear Rotors SG Racing is quickly switching to its latest gen 3 silver grey disc rotors, all SG and SG2F disc rotors will remain in the gen 1 disc coating, for the foreseeable future. SG2F/SG2FC discs/rotors will have both a black ring and hub.  The pad swept area quickly wears down to the natural iron finish on the disc ring and any unswept areas remain protected by the black coating unless burned off, such as on outer edges, due to hard use and higher temperatures, which cannot be avoided.
 
‘SG2F’ rotors that serve as a direct replacement for performance vehicles where 2-piece brake rotors are fitted as standard.
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.
 
The benefits of using a high-performance metallurgy are evident after testing EBC Brakes Racing’s 2-piece floating rotors against the recently introduced and extremely harsh ‘Reg 90’ dynamometer routine. The EBC 2-piece rotors completed two full test cycles back-to-back with zero disc cracking and no visible disc crazing. To put this into perspective, most OE discs show signs of cracking at stop 40 and then fail at 50% through just one R90 test, at stop 80 of 150. The quality of EBC’s metallurgy coupled with the fact that the disc is fully-floating in its design allows EBC’s 2-piece rotors to outperform most OE discs by a factor of over 4x in the ‘R90 Thermal Fatigue Test’.
 
The mounting bells used in EBC Brakes Racing’s 2-piece rotors are each precision machined from a billet of aerospace grade aluminium, ensuring they are both strong and lightweight.
The bells are subsequently black anodised, providing an aesthetically pleasing and corrosion-resistant finish, allowing the mounting bells to be re-used for multiple outer friction rings thus leading to lower long-term running costs.
 
Note: * All ‘SG2FC’ 2-piece floating conversions will seamlessly replace the OEM 1-piece rotor and are designed to integrate with the OE caliper and pads with no vehicle modifications necessary.
