MMX Carbon Ceramic Front Rotor Conversion 380x36mm for G8X BMW M2 / M3 / M4
The MMX G8X M2 M3 M4 Carbon Ceramic Front Rotor is the ultimate braking upgrade for S58-powered M cars running the factory iron brake system. This is a true iron-to-CCB conversion: the carbon ceramic rotor bolts directly to your OE iron-brake calipers and brackets with no recalibration, and instantly delivers the fade resistance, thermal capacity, and unsprung-mass savings that only carbon ceramic can offer. At 6.9 kg per disc (46% lighter than the factory steel unit), the difference is felt in steering response, ride compliance, and pedal feel from the very first stop.
Features
- True iron-to-CCB conversion, bolts to the factory iron-brake calipers and hardware with no caliper, bracket, or recalibration changes
- Carbon ceramic rotor ring runs dramatically cooler than steel and resists fade across consecutive hard stops
- 46% lighter than the OE steel disc, reducing unsprung and rotating mass for sharper turn-in and improved ride compliance
- 2-piece floating design pairs the ceramic ring with a separate anodized black hat, allowing radial and axial expansion under extreme heat
- Cross-drilled rotor face evacuates gas and pad material under hard use, a profile CCM tolerates exceptionally well
- 1-year manufacturer warranty against defects in materials and workmanship

- Sold per disc position as a front set. Contact us with your build details if you are unsure of your factory brake configuration.
Frequently Asked Questions
Will this work with my factory calipers?
Yes. The G8X M2 M3 M4 Carbon Ceramic Front Rotor is engineered as a direct plug-and-play upgrade for the factory iron brake hardware. No caliper swap, bracket modification, or recalibration is required.
My car came with factory carbon ceramic brakes. Can I use this rotor?
No. This is an iron-to-CCB conversion product, designed only for cars that left the factory with iron brakes.
What pads should I run with it?
MMX pairs these rotors with the Pagid RSL29 carbon ceramic pad compound, developed specifically for use with MMX carbon ceramic discs.
How much lighter is it than the stock rotor?
Each disc weighs 6.9 kg, a 46% reduction versus the factory steel unit, which directly reduces unsprung and rotating mass.
Is cross-drilling safe on carbon ceramic?
Yes. Unlike drilled iron rotors, carbon ceramic material has the thermal mass and surface integrity to handle a drilled profile without the associated cracking risk.
Do I need the rear conversion as well?
The front set works on its own, but pairing it with the matching 370x24mm rear rotor completes the full iron-to-CCB conversion and keeps brake balance consistent.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only.

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well.
For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at
