Serious stopping power for your BMW M-lite. This front axle rotor set delivers a true upgrade over factory equipment with a two piece construction and a ten-slot surface that refreshes the pad face and maintains confident bite on fast road and track day use. Supplied as a matched pair at 340 mm diameter, they drop straight onto cars with the M Sport calipers.
Perfect fitment for:
- BMW M140i B58
- BMW M135i N55
- BMW 1 Series and 2 Series F20, F21, F22, F23 fitted with the M Sport front braking package and 340 mm hardware
Why choose this two piece slotted rotor set
- Two piece construction helps cut unsprung weight and manages heat more effectively than a one piece design, giving consistent performance on spirited drives.
- Ten-slot pattern clears dust and gases to keep the pad working efficiently, improving pedal feel in wet and dry conditions.
- Direct bolt-on fitment with OEM callipers and backing plates, no extra brackets required.
- Engineered for durability and long service life on fast road cars, while coping with the demands of occasional circuit use.
- Balanced and machined to tight tolerances for smooth, vibration-free operation.
What you get
- Front rotor pair, left and right, 340 mm slotted, two piece composite design
- Designed as an OE replacement upgrade for cars already running the 340 mm M Sport setup
