EBC Two-Piece Fully-Floating Disc Conversion (Front Pair) for BMW M2 CS (F87) 400mm SG2F025

• Precision Engineering:

  • Designed, manufactured, and run-out tested in the UK to ensure uncompromising quality.

• Versatile Conversion Options:

  • Available as a direct replacement for performance vehicles originally equipped with 2-piece brake discs, or as an easy bolt-on upgrade for vehicles fitted with standard 1-piece cast iron discs.
  • For vehicles with a 2-piece pin-drive disc as standard, the EBC SG2F 2-piece disc upgrade seamlessly converts to a fully floating 2-piece system without any vehicle modifications.
  • No modifications are necessary for these 2-piece disc conversions.

• Enhanced Thermal Performance:

  • Features 48 directionally-handed, curved vanes that efficiently dissipate heat, helping to maintain lower operating temperatures and delay the onset of brake fade.

• Lightweight & High-Quality Construction:

  • Lighter than OE discs, these 2-piece brake discs are engineered for superior performance.
  • The outer friction rings are cast from a high-copper, high-carbon G3500 disc alloy, while the bells are precision machined from aerospace-grade aluminium and hard anodised for excellent durability and appearance.

• Advanced Floating Design:

  • The cast iron friction ring 'floats' on EBC's patented SD-Drive technology bobbins, allowing up to 3mm of expansion and contraction under the extreme heat of heavy braking.
  • All bobbins are crafted from a single piece of stainless steel, which prevents corrosion and ensures long-term free-floating performance.
  • Each bobbin location is equipped with an anti-rattle spring clip, ensuring silent operation without the common noise issues seen in other full race 2-piece disc systems.

• Performance and Cost Benefits:

  • Upgrading to an EBC 2-piece disc reduces unsprung rotational mass, leading to sharper turn-in, improved tyre road holding, better fuel economy, and increased horsepower at the wheels.
  • When the cast iron friction ring wears out, it can be replaced independently, allowing the centre hub and stainless bobbins to be reused and reducing long-term running costs.

EBC's mission in developing these brake discs was to engineer the highest quality 2-piece discs possible. Constructed from the finest materials, they offer exceptional performance and durability—making them an ideal, cost-effective upgrade for both road and track applications.
