M240i Front Rotors, Factory Calipers
Gold wheels and red M-marked calipers frame this blue BMW M240i. The documented change is at the front, where the factory BMW calipers work with STOPFLEX 374mm long-fiber carbon ceramic rotors. The close-ups show the drilled friction face and STOPFLEX rotor hat.

Keeping the red BMW calipers makes this a focused front-rotor upgrade. The material change is the purchasing decision: STOPFLEX says a like-sized carbon ceramic disc can weigh less than an iron disc, with the saving dependent on dimensions. Ask for the weights of the confirmed 374mm rotor pair when comparing options, so the comparison reflects the parts you would actually buy.
Order scope matters just as much for a front-only project. STOPFLEX's M240i listing defaults to a full-car set but allows front-only orders after confirmation. A useful quote should identify the front discs, matching ceramic-compatible pads and fitting hardware together. That keeps the calipers in place while treating the new friction surfaces as a complete, matched job.
Identify Your M240i Before Ordering
The G42 M240i rotor listing is a generation-specific reference that includes a 374mm front option. The year and chassis of this case are not supplied, so that listing is not confirmation of its exact fitment. Provide the chassis, current rotor measurements, caliper details and wheel specifications for review.
Send your M240i year, chassis and front brake details to check a matching retained-caliper rotor package.
