What is the difference between the GiroDisc Dimpled Slotted Front Rotors for W463 and the standard version?

The GiroDisc Dimpled Slotted Front Rotors for W463 carry a dimpled and slotted friction face and are sold as part A1-260DS. The standard A1-260 rotor is a separate part that GiroDisc supplies with caliper spacers and longer bolts. Both are two-piece floating assemblies for the G63 with aluminum hats and GiroDisc iron rings.

Do these rotors work with the original G63 front calipers?

Yes. GiroDisc describes the A1-260DS as a direct replacement for the factory disc that bolts to the vehicle and works with the original calipers. No modification is needed, which also means the factory brake bias and the ABS behavior stay as Mercedes-AMG engineered them.

How many drive pins hold each dimpled ring to its hat?

Ten. Each ring is fixed to its aluminum hat by ten high-strength alloy steel drive pins that GiroDisc makes in the USA and cadmium plates against corrosion. The pins take the braking load while allowing the ring to float, and they are secured by class 12.9 cap screws with hardened washers.

Can the dimpled rings be replaced without buying new hats?

Yes. The hats are reused for the life of the rotor. Once the rings wear to the minimum thickness marked on the hat and the ring edge, a pair of D1-260DS dimpled and slotted replacement rings bolts on with new hardware supplied, and the cap screws are set to no more than 60 in-lb.

Will the floating rings make noise at parking lot speeds?

No, not under normal conditions. GiroDisc fits anti-noise spring washers to the drive pins on the rotor side. They let the ring expand as it heats yet hold it firmly enough when cold to remove the rattle that floating rotors without them can produce at walking pace.

Description

GiroDisc Dimpled Slotted Front Rotors for W463 Mercedes-AMG G63

GiroDisc’s Dimpled Slotted Front Rotors for W463 Mercedes-AMG G63 put a dimpled and slotted friction face on GiroDisc’s two-piece floating design, for owners who want that surface on the front of the big AMG. The rotor bolts straight on in place of the original disc and works with the factory calipers, so there is nothing to modify. Its ring is GiroDisc’s own cast iron, poured in the USA and machined in Bellingham, Washington, and it runs on ten cadmium-plated alloy steel drive pins.

Design and Performance

Ten drive pins carry the braking load from the ring to the 6061-T6 aluminum hat while letting the ring move axially and radially as it heats. Class 12.9 cap screws with hardened washers hold the pins, and anti-noise spring washers stop the cold rattle floating rotors are known for. The GiroDisc Dimpled Slotted Front Rotors for W463 also pump air through curved internal vanes, and the two-piece build trims rotating and unsprung mass.

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.
