Are the hats included with the dimpled ring pair?

No. The pair includes a left ring, a right ring and new mounting hardware. The aluminum hats already fitted to the G63 are reused, which is what keeps the running cost of a two-piece rotor below that of buying complete assemblies each time the iron wears out.

Can another brand of ring be fitted to the G63 dimpled hats?

No. GiroDisc designs its hats and rings to work together. Rings from other manufacturers are not designed for GiroDisc hats, and GiroDisc states that its own rings are intended only for GiroDisc hats, not for other brands or for factory two-piece rotors.

What torque do the cap screws take after a G63 front ring change?

GiroDisc sets a ceiling of 60 in-lb, which is 7 Nm, for the cap screws that hold the drive pins. They are not meant to clamp the ring tight. The floating mount relies on a small amount of movement, so the screws can look loose even when correctly installed.

How is a cracked G63 front ring handled?

GiroDisc advises replacing the rings if a crack leads to the outer edge, even when the thickness remains above the marked minimum. The D1-260DS pair then goes onto the existing hats with the new hardware supplied, the worn rings are retired and the hats return to service.

GiroDisc Dimpled Slotted Front Replacement Rings for W463 Mercedes-AMG G63

GiroDisc’s Dimpled Slotted Front Replacement Rings for W463 Mercedes-AMG G63 are the service part for the A1-260DS front rotors, putting new dimpled and slotted iron on the existing aluminum hats. The ring measures 410mm across, per GiroDisc, and the pair ships with new mounting hardware so the floating mount is renewed along with the friction surface. GiroDisc pours the iron in the USA and machines it in Bellingham, Washington. For a G63 owner who chose the dimpled look, these keep it consistent through every ring change.

Fitment and Installation

Only GiroDisc hats take these rings; other brands and factory two-piece hats are not compatible. The swap is a bench job once the rotors are off: unbolt the worn rings, fit the GiroDisc Dimpled Slotted Front Replacement Rings for W463 with the new hardware, and tighten the cap screws to no more than 60 in-lb. Each rotor is handed, so keep left and right rings on the correct hats.

About GiroDisc

The 2-piece floating design sheds unsprung and rotating mass while remaining street-friendly, delivering race-proven braking for track and street use alike.

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.
