EBC Rear Floating 2-Piece Brake Rotors BMW M3/M4 F80/F82/F83

When developing these brake discs, the mission was to engineer the highest quality 2-piece brake discs possible.

These discs are manufactured from the finest materials and consequently are some of the highest quality 2-piece discs sold on the market at any price point. All outer friction rings are cast from a high-copper high-carbon G3500 disc alloy. The bells are precision machined from aerospace grade aluminium then hard anodised for great looks and excellent durability.

The cast iron outer ring 'floats' on EBC's patented SD-Drive technology bobbins, allowing the friction ring to expand and contract freely by up to 3mm when subjected to the extreme heat generated from hard braking.

All bobbins are machined from a single piece of stainless steel. This prevents unsightly corrosion and ensures the outer ring continues to float freely even after years of exposure to the elements. This means that EBC Racing's 2-piece floating discs offer a low maintenance solution that are at home on both the public roads and the race track. Each bobbin location also features an anti-rattle spring clip, meaning these discs are totally silent in operation and do not have the 'off brake disc rattle' that plagues many other full race 2-piece disc systems.

Upgrading to an EBC 2-piece disc will shave crucial kilogrammes off a vehicles un-sprung rotational mass, leading to sharper turn in, improved tyre road holding, better fuel economy and an increase to BHP at the wheels. Best of all, when the cast iron friction ring becomes worn after a period of use, the outer ring alone can be replaced, allowing the centre hub and stainless bobbins to be re-used, reducing long term running costs.

Features :

• Our Fully-Floating 2-Piece Brake Discs will be supplied with either a thermic black or standard metallic silver disc ring
• Price per axle set (incl. LH and RH disc)
• Designed, manufactured and run-out tested in the UK
• Sold either as a direct replacement for performance vehicles where 2-piece brake discs are fitted as standard or as a simple bolt-on 2-piece floating upgrade for vehicles with 1-piece cast iron discs fitted as standard. Where the vehicle has a 2-piece pin-drive brake disc as original equipment, EBC's SG2F 2-piece disc upgrade seamlessly replaces the pin-drive disc with a true fully-floating 2-piece disc, whilst requiring no vehicle modifications
• No vehicle modifications are required for 2-piece disc conversions
• 48 directionally handed curved vanes for effective heat dissipation
• Lower operating temperatures help delay the onset of brake fade
• Lighter weight than OE discs

Fitments :

• BMW M3 F80 2014-2020
• BMW M4 F82 2014-2020
