EBC Slotted Front Rotors 312 mm - BMW 4 Series F3x 420
Transform the stopping performance of your BMW 4 Series F3x 420 with EBC’s slotted and dimpled front rotors. Sized at 312 mm for the front axle, these precision-machined discs promote rapid heat dissipation and efficient debris clearance, delivering confident braking on fast road drives and daily use alike.
The directional groove pattern continually refreshes the pad face by clearing dust and gases, while the dimpled surface assists with heat management without the cracking risks associated with fully drilled discs. The result is sharp bite, reliable feel and strong resistance to fade when you need it most.
Key advantages
- 312 mm front rotors engineered for BMW 4 Series F3x 420 applications
- Slotted and dimpled faces to manage heat, dust and gas build-up under hard braking
- Improved pedal response and consistent stopping power on spirited road drives
- Gold-tone zinc plating on non-contact areas for corrosion protection and a smart look
- Great pairing with EBC performance pads such as Yellowstuff for an all-round upgrade
- Designed for drivers seeking dependable, repeatable braking performance
Proven on our cars and customer builds
We have installed these EBC slotted front discs on our own BMW projects and many customer cars. Feedback has been outstanding, with owners praising the crisper initial bite, confidence-inspiring pedal feel and dependable performance in repeated stops. Any light whirr from the grooves typically settles after a short bedding-in period.
Finish and durability
A protective gold zinc passivate helps guard the non-swept areas against surface corrosion, keeping hubs and edges looking tidy behind your wheels. The working faces clean up as the pads bed in.
Fitment guidance
Front axle - 312 mm diameter. Please confirm your existing disc size and fitment before ordering. If you are unsure, get in touch and we will help you verify compatibility for your specific F3x 420 model.
