Do these BMW G8x carbon ceramic rotors work with the factory iron calipers?

Yes. The BMW G8x carbon ceramic rotors front set 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 G8x came with factory carbon ceramic brakes. Can I use these BMW G8x carbon ceramic rotors?

No. The BMW G8x carbon ceramic rotors front set is an iron-to-CCB conversion designed only for cars that left the factory with iron brakes. If your car already has factory CCB, this rotor is not compatible as a direct bolt-on.

Is cross-drilling safe on these BMW G8x carbon ceramic rotors?

Yes. Unlike drilled iron rotors where surface cracking is a risk under sustained thermal cycling, carbon ceramic material has the thermal mass and surface integrity to handle a drilled profile without that concern. The cross-drilled face evacuates gas and pad material effectively under hard use.

What pads are recommended with these BMW G8x carbon ceramic rotors?

MMX pairs these rotors with the Pagid RSL29 carbon ceramic pad compound, developed specifically for MMX carbon ceramic discs and available as the matching front pad set (MMR27-1610-F) linked in the Notes section.

Do I need the rear BMW G8x carbon ceramic rotors as well?

The front set works on its own, but pairing with the matching 370x24mm rear carbon ceramic rotor (MMR30-1604R) completes the full iron-to-CCB conversion and keeps thermal behavior and brake balance consistent front to rear.

Description

MMX Carbon Ceramic Front Rotor Conversion 380x36mm for G8x BMW M2, M3, and M4

BMW G8x carbon ceramic rotors front set from MMX Performance is the ultimate braking upgrade for S58-powered M cars running the factory iron brake system covering the G87 M2, G80 M3, and G82/G83 M4. This is a true iron-to-CCB conversion: the BMW G8x carbon ceramic rotors front set bolts directly to the OE iron-brake calipers and brackets with no caliper swap, bracket modification, or recalibration required, delivering the fade resistance, thermal capacity, and unsprung-mass savings that only carbon ceramic can offer without the cost and complexity of a full OEM CCB retrofit. At 6.9kg per disc, these are 46% lighter than the factory steel unit, a reduction that is felt immediately in steering response, turn-in sharpness, and ride compliance the kind of difference that comes only from removing mass at the wheel, where it has the greatest effect on unsprung and rotating inertia. The carbon ceramic rotor ring runs dramatically cooler than steel and resists fade across consecutive hard stops, backed by a 2-piece floating design that pairs the ceramic ring with a separate anodized black hat, allowing radial and axial expansion under extreme heat without the distortion that affects single-piece rotors. A cross-drilled face evacuates gas and pad material under hard use, a profile that carbon ceramic material handles far better than iron due to its thermal mass and surface integrity.

Notes

Fits G8x M cars with factory iron brakes only. Cars equipped with factory carbon ceramic brakes (CCB) cannot use this rotor as a direct bolt-on
Pairs with the 370x24mm rear carbon ceramic rotor (MMR30-1604R) for a full iron-to-CCB conversion, and with the Pagid RSL29 carbon ceramic front pad set (MMR27-1610-F).

Additional Information

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.

Shipping Policy

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. Please review the full Terms & Conditions here.

BP Pricing Difference

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 sales@bulletproofautomotive.com with any inquiries.
