What brake pads do the BMW G8x carbon ceramic rotors rear set require?

The BMW G8x carbon ceramic rotors rear set requires carbon ceramic-specific brake pads — standard iron rotor pads are not compatible and must not be used. The system is compatible with all OE-shaped ceramic-specific pad compounds; using the correct compound is essential for both performance and rotor longevity.

How much lighter are the BMW G8x carbon ceramic rotors rear than the OE steel units?

Each rear rotor weighs 4.45kg — 46% lighter than the factory steel unit. At the rear axle this reduction in unsprung and rotating mass improves acceleration out of corners and sharpens overall handling response.

Do the BMW G8x carbon ceramic rotors rear bolt on without modification?

Yes. The BMW G8x carbon ceramic rotors rear set is a direct bolt-on replacement for the factory steel rear rotors with no modifications, bracket changes, or caliper swaps required. The 370x24mm dimensions match the factory G8x rear brake rotor specification.

Should I also upgrade the front BMW G8x carbon ceramic rotors at the same time?

For a complete front-to-rear CCB conversion with matched thermal behavior and brake balance, pairing these rear BMW G8x carbon ceramic rotors with the matching 380x36mm front set — linked in the Notes section — is recommended. The rear set works standalone but the full conversion delivers better overall brake balance.

What is the benefit of full floating 2-piece construction on the BMW G8x carbon ceramic rotors?

The fully floating mounting system allows the carbon ceramic rotor ring to expand thermally without transferring stress to the aluminum bell, maintaining dimensional stability and reducing the risk of cracking under the extreme temperatures generated by sustained hard braking on track.

Description

MMX 2-Piece Carbon Ceramic Rear Brake Rotor Conversion 370x24mm for G8x BMW M2, M3, and M4

BMW G8x carbon ceramic rotors rear set from MMX Performance is a 370x24mm 2-piece carbon ceramic rear brake rotor conversion for the G87 M2, G80/G81 M3, and G82/G83 M4 engineered as a direct bolt-on replacement for the factory steel rear rotors with no modifications required. Carbon ceramic fiber made from a 3D multi-directional matrix delivers superior heat resistance and significantly reduced weight versus steel, with each rotor weighing just 4.45 kg, 46% lighter than the OE steel unit. At the rear axle that weight reduction improves acceleration, sharpens handling response, and enhances overall efficiency through reduced unsprung and rotating mass. A fully floating 2-piece rotor and bell assembly maximizes thermal stability and durability under high-stress braking, and precision-drilled rotors promote optimal airflow for consistent braking performance on both road and track. The BMW G8x carbon ceramic rotors rear set requires carbon ceramic-specific brake pads compatible with all OE-shaped ceramic-specific pad compounds. Matching front carbon ceramic rotors (380x36mm) are available separately for a complete front-to-rear CCB conversion.

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.
