Turner Motorsport 400mm Front 2-Piece Floating Wave Brake Discs/Rotors, Drilled & Slotted - BMW M5 F10 / M6 F12 F13 F06 (F1X) - High Carbon Performance Upgrade 400x36

Serious stopping power for BMW M5 and M6 owners looking for a true performance brake upgrade. These wave-pattern, floating two-piece brake discs transform pedal feel, heat control and aesthetics on F1X-platform cars. If you want lighter, stronger, better cooling and a unique look, this is the premium choice for fast-road use and enthusiastic driving.

Engineered with a lightweight 6061-T6 aluminium bell that is hard anodised in matte black, paired with a high-carbon grey cast iron ring, this assembly cuts unsprung mass and rotational inertia for sharper acceleration and more confident braking. The distinctive wave profile trims weight at the edge of the disc where it matters most, while the perforated and grooved faces help clear gases and debris for consistent bite and reduced fade.

We run these on our own cars and customer feedback has been superb. Expect a firmer, more consistent pedal, reduced pad knockback and excellent stability under repeated heavy stops. Non-friction surfaces, including the internal vents, are coated to resist salt and grime, helping the discs stay looking fresh for longer.

• Fitment: BMW M5 and M6 on the F1X platform, front axle
• Size: 400 x 36 mm
• Construction: two-piece floating with precision-machined 6061-T6 aluminium bell, matte black hard anodised
• Ring material: FC-30 high carbon grey iron for superior heat management and wear at elevated temperatures
• Friction faces: perforated and grooved for gas evacuation and pad deglazing
• Wave outer profile to reduce inertia and improve response
• Precision ground faces for parallelism and smooth pad bed-in
• Heat treated and dynamically balanced for vibration-free operation
• Full-float hardware allows the ring to self-centre, improving pad wear and reducing drag and knockback
• Independent radial and lateral expansion minimises thermal stress and helps maintain a consistent pedal
• Reduced heat transfer to the hub and bearings thanks to minimal contact area between ring and bell
• Non-friction surfaces and internal vanes coated for corrosion resistance

Usage note: for dedicated circuit cars, a grooved-only setup is recommended to minimise the chance of thermal stress cracking under extreme track conditions. For daily use, spirited driving and fast-road setups, these discs deliver outstanding performance and longevity.

Why upgrade:

• Improved pedal consistency and confidence under repeated heavy braking
• Lower unsprung weight and quicker response compared with one-piece discs
• High-end materials and finishing for durability in UK road conditions
• Standout look behind OEM or aftermarket wheels
