The F87 M2C is well-regarded for its performance and handling. For those seeking more from the driving experience, upgrading components is key. After gracing the ride with a full suite of OEM M Performance carbon fiber parts, a suspension system, 763M forged wheels, and high-performance Akrapovič and Eventuri intake and exhaust systems, the owner went for an INSPEED carbon ceramic disc kit.

The upgrade to 763M forged wheels already reduced weight, and switching to these discs significantly lowers unsprung weight. This refers to the mass supported by the suspension, which directly impacts handling responsiveness. Lighter unsprung weight results in quicker reactions to road conditions, during acceleration, braking, and cornering. I know some may not agree with these, but I'm just trying to explain the data we get from manufacturers in layman's terms, so don't shoot the messenger.

The original 400mm front discs weighed approximately 13.54 kg, and the 370mm rears were about 9.34 kg. In contrast, the INSPEED carbon-ceramic discs weigh around 8.17 kg and 6.14 kg respectively, a total weight reduction of about 37.5%. If you're on a journey for weight reduction for whatever reasons, these might come in handy to know.

Beyond weight savings, the upgrade offers better durability, higher heat resistance, and outstanding performance, often lasting over 300,000 km under normal driving conditions.

You know what's faster than an M2C though? This link to my iCARMIX website:

How much for all four rotors?

Do you make these yourself? Who makes these?

If you are considering running CCB rotors, the CCB rotors listed below are a better option and come with a set of brake pads. I believe they offer CCB rotors in sizes that fit the standard blue brakes. The biggest advantage is the CTECARBON rotors use continuous woven layers to make their rotors vs. the oem rotors use discontinuous/chopped fibers in their construction which has lower structural integrity. They also offer their conventional CCB rotors which are more expensive but cheaper compared to oem CCB rotors.

Should be PRC.

The brand is INSPEED. It's a new brand I've been working with, cautiously. So far their quality is very good, which makes their price very competitive in this market.

around $6,700 USD

These appear to be carbon ceramic discs with very few vanes, no wear indicators, and no mention of pad performance, life expectancy, safety testing, booster replacement, or coding.

Appears to be a recipe for disaster to me.

Just for show and won’t stop any better than the stock set up especially with the stock booster.

Hi there, nice of you to ask about them.
Not only we have data sheet, we also have videos from the track test and the manufacturing process, as well as statements from the customers who sport these babies for a few months now.
That's a recipe for a good partnership to me.

P.S.
I'll try to upload the videos here, and in case anyone can't see them, I can also send them in private or on Whtsapp.

All of your data are for NVH, % of noisy stops, and SPL? Rotor performance and life are more important than % of noisy stops. What about stopping distances after repeated stops from 75 mph, 100 mph, etc? How many cycles before the rotors need to be replaced? How do you know when they need to be replaced? How much mass can each rotor lose before needing to be replaced? Can the friction surface be reapplied? If so, how many times? Do you offer street and track pads? What material is used for your mounting hats? How do you prevent hat mounting hardware from developing axial preload? Your floating rotor design appears to use a steel washer that slides in a radial grove. How due you minimize differential circumferential thermal growth between the washer and radial grove in the hat? The washer appears to start in a position at the aft portion of the rotor so how does the hat grow freely outward radially as the rotor effectively doesn’t grow relative to the hat? At elevated temperatures, does the drag between the washer and hat affect the free growth of the hat? How many radial cooling vanes per rotor? What’s the height and width of each cooling vanes? You didn’t answer the question, are this made in China?
