Which AMG models take the GiroDisc Front Rotors for Mercedes-Benz S63?

GiroDisc lists the Front Rotors for Mercedes-Benz S63 for the S63, S65, CL63 and CL65 AMG, with the S-Class application on the W221 generation. Because these names have been used across more than one generation, send us your model year and we will confirm the match before shipping.

Do the AMG front rotors keep the factory calipers?

Yes. GiroDisc builds them as a direct replacement for the original discs, so the AMG front calipers bolt back on without modification. With the original rotor size and calipers retained, the brake bias and ABS efficiency Mercedes engineered for the car are maintained.

Why fit floating rotors to a large AMG sedan?

A heavy, powerful car puts a great deal of heat into its front brakes. A floating ring can expand on its drive pins without pulling against the hat, and the curved vanes pump air through the disc, so the rotor copes better with repeated stops from high speed.

Are the S63 and S65 front rotors noisy at low speed?

No. Anti-noise spring washers on the rotor side of each drive pin hold the ring firmly when cold, which stops the rattle older floating designs were known for. The ring is still free to expand once it heats, so refinement and performance are both kept.

Can the AMG front rings be replaced without new hats?

Yes. Once the iron reaches the minimum thickness marked on the hat and ring edge, or if a crack reaches the edge, only the rings need replacing. Ask us for the matching GiroDisc ring part number and we will supply a pair with new hardware.

Description

GiroDisc Front Rotors for Mercedes-Benz S63, S65, CL63 and CL65 AMG

GiroDisc’s Front Rotors for Mercedes-Benz S63, S65, CL63 and CL65 AMG models bring a two-piece floating disc to large, fast AMG sedans and coupes, where the front brakes work hard on every stop. Each rotor bolts on in place of the factory disc and keeps the original AMG calipers, brake bias and ABS calibration. Twelve cadmium-plated drive pins carry a slotted ring of GiroDisc’s USA-poured iron on a 6061-T6 aluminum hat. It suits the owner who drives an AMG flagship briskly and wants brakes that stay consistent.

Design and Performance

The floating mount lets the iron ring grow with heat while the drive pins carry the braking load, which limits distortion after repeated stops from high speed. Curved vanes, developed in racing, pump air from the hub out through the disc. Spring washers on the rotor side of each pin keep the assembly quiet when cold, which matters on a car built for refinement.

Features

Direct replacement for the factory front discs, no modifications
Twelve high-strength alloy steel drive pins made by GiroDisc in the USA
Class 12.9 cap screws with hardened washers

About GiroDisc

GiroDisc designs, manufactures, and sells 2-piece, fully floating brake rotors for a wide range of performance vehicles. Every major component, including the hats, rotor rings, and drive pins, is manufactured in-house at their facility in Bellingham, Washington, from domestically sourced materials. GiroDisc rotors use a proprietary high-carbon iron ring formulated for superior metallurgy and thermal performance, paired with reusable machined-aluminum hats that reduce the long-term cost of maintaining a high-performance brake system. 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.
