What do the GiroDisc BMW F8X 380mm rear rings include?

The GiroDisc BMW F8X 380mm rear rings ship as a pair of 380mm rear rings (D2-220) with replacement hardware. The only parts you reuse are your existing GiroDisc hats, making this a cost-effective refresh of a worn rear rotor assembly.

Do I need the complete rotor first to use the GiroDisc BMW F8X 380mm rear rings?

Yes. The GiroDisc BMW F8X 380mm rear rings are replacement rings only and fit GiroDisc hats exclusively, so you must already own the complete GiroDisc rear rotor assembly (A2-220) before fitting them.

What is the difference between the 380mm and 368mm GiroDisc BMW F8X rear rings?

The GiroDisc BMW F8X 380mm rear rings (D2-220) are for the 380mm A2-220 rear rotor, while the 368mm rings (D2-186) are for the 368mm rear rotor. Confirm which GiroDisc rear rotor diameter you have before ordering.

Will the GiroDisc BMW F8X 380mm rear rings fit OEM or other-brand hats?

No. Unless specifically noted, the GiroDisc BMW F8X 380mm rear rings work with GiroDisc hats only, including no fitment to factory 2-piece rotor hats. They are not compatible with OEM or other-brand hats.

GiroDisc Rear 380mm Slotted Rings for F8x BMW M2 / M3 / M4

BMW F8X 380mm rear rings from GiroDisc are 380mm rear replacement rotor rings for the GiroDisc 380mm rear rotor assembly (A2-220) on the F8X BMW M2, M3, and M4 with red, silver, or gold calipers, including carbon ceramic (CCM) cars. Sold in pairs and supplied with replacement hardware, these GiroDisc BMW F8X 380mm rear rings let you refresh worn rings while reusing your existing GiroDisc aluminum hats, a far more economical path than buying complete rotors again. They are the wear item for the two-piece GiroDisc rear rotor, so you must already own the complete rear rotor assembly (A2-220) before these rings can be used.

Why the GiroDisc BMW F8X 380mm Rear Rings?

Because the two-piece GiroDisc design keeps the aluminum hat separate and reusable, you only ever replace the wear item, the ring itself, keeping long-term brake maintenance costs well below a one-piece rotor. The GiroDisc BMW F8X 380mm rear rings restore the braking surface of your existing A2-220 rear rotors without the cost of a complete new assembly, using the same GiroDisc ring engineering as the original rotors.

Fitment: Red, Silver, or Gold Calipers Including CCM

The GiroDisc BMW F8X 380mm rear rings are for M2, M3, and M4 cars with red, silver, or gold calipers, including carbon ceramic (CCM) cars, that run the GiroDisc 380mm rear rotor assembly (A2-220). Confirm your caliper color and that you have the 380mm GiroDisc rear rotor before ordering.

What You Get

The GiroDisc BMW F8X 380mm rear rings ship as a pair with replacement hardware, and the only parts you reuse are your existing GiroDisc hats. Unless specifically noted, GiroDisc replacement rings are designed to work with GiroDisc hats only; they are not designed for use with other brands, including hats from cars equipped with 2-piece rotors from the factory. You must already own the complete GiroDisc rear rotor assembly (A2-220) before these rings can be used.

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.
