Why enthusiasts choose this 380 mm front rotor upgrade

• Direct fitment for BMW F80 M3 and F82 M4 models with Brembo front callipers
• Two-piece construction with a CNC-machined billet steel friction ring and hard-anodised alloy bell for strength and weight optimisation
• Vented discs with handed cooling vanes for efficient airflow and thermal stability across the front axle
• Individually CNC-machined from solid billet, then heat-treated for exceptional durability and resistance to warping, cracking and fade
• Ultra-precise finish, manually ground to near 0.015 mm for true running and confidence at high speed
• Outstanding ultimate tensile strength, rated at 57 kg per square mm for serious performance use
• Ideal for fast road, spirited driving and track-day sessions while retaining OE compatibility

Performance you can feel

Expect repeatable braking, improved pedal stability and a strong initial bite that stays consistent as temperatures rise. The two-piece design controls heat transfer to the hub, reduces unsprung mass compared to many one-piece alternatives and helps protect bearings and calliper seals during intensive sessions.

Bespoke manufacturing quality

Each rotor is produced from a solid steel billet, never cast, then heat-treated and slowly cooled to unify the internal structure. The rings are finished by hand and mated to a precision alloy bell that is hard anodised for corrosion protection. The result is a rotor set that resists fade, knock-off and uneven wear while extending the life of both discs and pads.
