BMW E60 M5 / E63 E64 M6 Front Brake Discs Rotors 2-Piece 374mm x 36mm Semi-Floating Slotted Grooved Drilled Vented Lightweight Pair - Performance Upgrade for S85 V10 - ECS Tuning OEM Replacement Fast Road & Track

Upgrade your BMW V10 M car with a front disc set engineered for serious stopping power and real-world performance. These semi floating, grooved and drilled front brake discs are a straight swap for the factory hardware, delivering a lighter, cooler and more consistent braking solution for fast road and track day use. Sized at 374 mm x 36 mm, this premium set is designed to work with the original calipers and hubs while offering a clear step up in bite, pedal feel and fade resistance.

By reducing unsprung mass by around 0.9 kg per side compared with standard discs, steering response sharpens, suspension control improves and rotational inertia drops for snappier acceleration and shorter braking distances. Customers love the transformation, and we run these discs on our own builds with excellent results for reliability and consistency.

Why this front disc upgrade stands out

• Straight fitment to the front axle of BMW E60 M5 and E63 E64 M6 with S85 V10
• Two piece semi floating construction to allow controlled thermal expansion and reduce the risk of distortion
• Lightweight hard anodised 6061 aluminium bell in matte black to cut mass and resist corrosion
• High quality grey cast iron friction rings for stable friction and superb heat capacity
• Precision heat treated rings for strength and durability under repeated heavy braking
• Grooved and drilled faces for pad deglazing, water and dust evacuation and rapid cooling
• Chamfered drillings and ball end milled slots to minimise stress risers and help prevent cracking
• Painted non-friction areas including internal vents to combat rust from salt and road grime
• Ground faces for parallelism and quick, clean pad bedding
• Includes stainless steel rotor set screws to replace rusty factory fasteners

Performance benefits you will feel

• Stronger initial bite and repeatable stopping on spirited drives and track sessions
