After an extensive development program, thousands of hours dyno testing, and the construction of a brand-new production line at the EBC Brakes World Headquarters in Northampton, UK, EBC are pleased to launch a new range of high performance 2-piece fully-floating brake rotors under the newly formed EBC Brakes Racing sub-brand.
Embarking on this project, the EBC Brakes Racing team’s mission was a clearly defined one; to develop the highest quality 2-piece floating brake rotor available on today’s marketplace. The componentry and technology used in these brake rotors exemplifies this pursuit of ultimate and absolute quality, culminating in a brake rotor that is perfectly matched to the highest braking demands of modern performance road and race cars.
Fully Floating SG2F Two Piece Rotors/Discs
"SG2F" rotors that serve as a direct replacement for performance vehicles where 2-piece brake rotors are fitted as standard, e.g. Nissan GT-R (R35).
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.
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.
G3500 Disc Alloy Friction Rings
Every outer ring is cast from the highest-grade disc alloy ‘G3500’. Derived from race technology and having a high carbon and high copper metallurgy, G3500 disc alloy has superior thermal conductivity and heat cycling durability for maximum brake rotor life and performance, particularly during harder driving or track driving.
48 Curved Vanes
All cast iron rings feature 48 curved vanes and are handed left and right, ensuring the vanes always rotate in the correct direction, giving maximum cooling efficiency.
Aerospace Grade Aluminium Bell
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.
Stainless-Steel SD-Drive™Bobbins
One of the smallest yet most innovative components used in EBC’s 2-piece fully-floating brake rotors is the stainless-steel SD-Drive™ bobbins. Unlike most competitor bobbins that are machined from steel and then zinc plated to cut cost, every SD-Drive™ bobbin is machined from a single piece of stainless-steel, meaning these bobbins can never rust.
More That Just No Rust
The lack of rust mean that EBC Racing’s 2-piece discs continue to look great through your wheels for years to come, the elimination of corrosion around the drive bobbins also ensures that the brake rotor continues to float freely throughout its entire life on the vehicle, providing a robust and low-maintenance solution to rotor radial heat expansion. Often you will hear misinformed brake technicians stating that ‘floating rotors are for track use and should not be used on the public road’, however EBC’s innovative stainless-steel SD-Drive™ bobbins provide a solution that allows our 2-piece rotors to be used on the road without regular maintenance, even in countries where adverse weather and road gritting are commonplace.
Prevents Disc Rattle
Additionally, every bobbin location makes use of a spring clip that prevents disc rattle. This ensures the rotors are totally silent during operation and can be used on the public roads without the off-brake "rattle" that plagues many other 2-piece floating rotors. SD-Drive™ bobbins operate on a ‘float in disc’ principle, meaning any wear resulting from regular expansion and contraction of the cast iron ring occurs in the slots in the cast iron ring itself, i.e. the component that becomes worn anyway after thousands of miles of braking. This allows the drive bobbins to be re-used for multiple outer friction rings, meaning only the outer ring needs to be replaced after a period of use, leading to significantly lower long-term running costs.
Lightweight with Lower Rotational Inertia
It is widely acknowledged that a vehicle is constantly working against its weight whenever it is moving. Weight blunts acceleration, reduces deceleration, and slows the rate of changes in direction. A brake disc clearly adds to a vehicles weight but more importantly it adds to a vehicle’s unsprung weight. The fact that the brake disc is rotating also results in it having a rotational inertia.
The impact that a brake disc has on vehicle dynamics is therefore more significant than any other weight-adding component on the vehicle. The fact that EBC Brakes Racing’s 2-piece rotors offer a significant weight saving compared to similar sized brake rotors leads to improvements in acceleration, ‘dive’ under braking, and tyre road holding. Particularly in the case of SG2FC 2-piece conversions, the improvements in response of the vehicle before and after the upgrade is profound and highly perceptible by the driver.
Features:
- Perfect for track use
- 48 directionally curved and handed vanes allow effective heat dissipation, resulting in lower operating temperatures that help delay brake fade
- Friction rings cast from G3500 metallurgy with a high copper/high carbon content
- Reduced weight compare to OE discs
