BMW F8X Brake Discs 400x36 - Floating Racing Kit Brembo 6-Piston 2NH

High-performance 400×36mm two-piece floating brake discs engineered as a direct OEM replacement for Brembo 2NH 6-piston brake systems. Designed for sustained high-temperature operation with improved thermal stability over standard one-piece BMW brake discs.

Technical Specifications

• Disc size: 400mm × 36mm

• Construction: Two-piece floating brake disc

• Caliper compatibility: BMW Brembo 6-piston

• Hardware: 12.9-grade high-strength steel floating bolts

• Bell: CNC aluminum, unpainted (anodized optional)

• Fitment: Direct OEM replacement (plug & play)

Technical Advantages

• Floating interface allows controlled radial expansion, reducing thermal stress and disc cracking

• Two-piece design improves heat dissipation and limits heat transfer to hub and bearings

• Reduced rotating mass compared to OEM one-piece BMW brake discs

• Improved braking consistency under repeated high-temperature cycles

• Fade resistance during track and aggressive driving conditions

Application

Direct upgrade for BMW 400×36 M-Performance brake discs, maintaining OEM calipers and mounting geometry while increasing thermal efficiency and durability.
