Do the GiroDisc Dimpled Slotted Rear Rotors for W463 match the dimpled front set?

Yes. The GiroDisc Dimpled Slotted Rear Rotors for W463 share the dimpled and slotted face of the A1-260DS front rotors, so a G63 fitted with both carries the same surface at all four corners. Front and rear are sold as separate pairs, and each pair has its own replacement ring part number.

Are the rear calipers or brake lines changed during installation?

No. GiroDisc lists this rotor as a direct replacement for the factory disc. It bolts to the hub, the original rear calipers refit as they were and the brake lines are untouched, so the bias and ABS calibration set by Mercedes-AMG stay exactly as delivered.

What do the curved vanes in the dimpled G63 rear rotor do?

The curved vanes inside the ring are shaped like the blades of a centrifugal pump. As the rotor turns they draw air in near the hub and push it out through the rim, moving heat out of the disc. Because the vanes are directional, each rotor is made for one side of the vehicle.

When should the dimpled rear rings be replaced?

Replace them when they reach the minimum thickness marked on the hat and on the edge of the ring, or sooner if a crack runs out to the ring edge. The replacement part is the D2-260DS ring pair, which comes with new hardware and bolts to the existing GiroDisc hats.

Where are the GiroDisc G63 rings made?

GiroDisc pours its proprietary high-carbon iron in the USA and machines every ring start to finish at its own facility in Bellingham, Washington. The hats are machined from US-sourced 6061-T6 aluminum, and the drive pins are also produced by GiroDisc to its own specification.

Description

GiroDisc Dimpled Slotted Rear Rotors for W463 Mercedes-AMG G63

GiroDisc’s Dimpled Slotted Rear Rotors for W463 Mercedes-AMG G63 give the rear of the G63 the same dimpled and slotted face as GiroDisc’s matching front set, so all four corners match. Each assembly floats a GiroDisc cast iron ring on a hat of US-sourced 6061-T6 aluminum, held by ten alloy steel drive pins that GiroDisc makes itself. The fit is direct: the rotor bolts to the hub, the factory calipers return unchanged and nothing on the vehicle is altered.

Construction

GiroDisc machines the ring from start to finish in Bellingham, Washington, after it is poured in the USA from the company’s proprietary iron. Curved vanes inside the GiroDisc Dimpled Slotted Rear Rotors for W463 work as a centrifugal pump, drawing air in at the hub and pushing it out through the rim. Class 12.9 cap screws with hardened washers secure the cadmium-plated drive pins.

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.
