The i4 M50 is already one of BMW's most capable electric sport sedans - killer acceleration, razor-sharp handling... but here's how we took it further without going full racecar mode.
Keep the factory calipers but upgrade to carbon ceramic rotors. We're talking serious unsprung weight savings (we'll get to numbers in a sec) while maintaining daily-driver practicality.

i4 M50 front rotor size：374mm
Original weight:14.88kg
INSPEED carbon ceramic disc:6.93kg

i4 M50 rear rotor size：345mm
Original weight:8.22kg
INSPEED carbon ceramic disc:4.49kg



*Lighter brakes = quicker acceleration (every EV lover's obsession)

*Superior heat resistance - maintains consistent braking performance even under extreme conditions

*Retains OEM caliper aesthetics if you're keeping the stealth look

*Still dust-free
