Bring smoother, vibration-free braking to your BMW i3 with the Dynamic Friction brake rotor 604-31123, a DFC GEOSPEC coated front rotor that installs as a direct-fit replacement for the 2014-2021 BMW I3 and 2018-2021 BMW I3S. It's a blank (non-drilled, non-slotted) casting built to match the form, fit, and function of the original equipment rotor.
This is a front-axle rotor, quality tested for long-lasting performance. Rotors are sold individually; replacing both front rotors together as a matched set is recommended for even, balanced braking. If worn or warped rotors are the cause of pulsation or reduced braking on your i3, this replaces the original.
Does this Dynamic Friction brake rotor fit my BMW i3?
Yes. It's cataloged as a direct-fit front rotor for the 2014-2021 BMW I3 and the 2018-2021 BMW I3S. Check the Buyer's Guide tab to confirm the match for your exact vehicle.
Is this a front or rear rotor?
This is a front-axle disc brake rotor per the catalog. It is not a rear unit.
What is the GEOSPEC coating?
It's DFC's rotor coating, which the manufacturer states provides superior corrosion protection over zinc and conventional painting.
Is this a blank rotor or drilled and slotted?
It's a blank rotor — a smooth, non-drilled, non-slotted face with a non-directional finish to promote faster break-in and smoother stops.
Should I replace both rotors at once?
Rotors are sold individually, so this listing is for one. Replacing both front rotors together as a matched pair is recommended for even, balanced braking.
