Which Ferraris take the GiroDisc Rear Iron Rotor Conversion?

GiroDisc lists the GiroDisc Rear Iron Rotor Conversion for the Ferrari 360 Challenge Stradale, the F430 and the 430 Scuderia. One pair covers the rear axle, and the front axle of each car has its own GiroDisc conversion part to match.

Do the factory Ferrari rear calipers need changing?

No. GiroDisc states the system is a direct replacement for the factory disc that bolts directly to the car and works with the original calipers. No modifications are required, and the rear brake hardware of the 360 Challenge Stradale, F430 or 430 Scuderia goes back on exactly as it came off.

How is the ring attached to the aluminum hat?

The ring floats on ten high-strength alloy steel drive pins made by GiroDisc in the USA and cadmium plated against corrosion. Class 12.9 cap screws with hardened washers secure the pins, and spring washers on the rotor side allow heat growth without cold rattle.

What gets replaced when the rear discs wear out?

Only the cast iron rings. The aluminum hats stay on the car and accept GiroDisc D2-110 replacement rings, which are sold as a pair with fresh hardware. That keeps the long-term cost of track use well below buying complete rotors every time.

Why does GiroDisc use curved vanes in the Ferrari rear rings?

Curved vanes were developed in racing to act as a centrifugal pump. As the disc spins, they draw air in through the hub and force it outward through the ring, carrying heat away between braking zones. On a heavy-braking circuit that steady airflow is what keeps disc temperatures under control lap after lap.

Description

GiroDisc Rear Iron Rotor Conversion for Ferrari 360 Challenge Stradale, F430 and 430 Scuderia

GiroDisc’s Rear Iron Rotor Conversion moves the rear axle of a 360 Challenge Stradale, F430 or 430 Scuderia onto GiroDisc’s two-piece iron discs. The 350mm ring is cast from GiroDisc’s proprietary iron, poured in the USA and machined start to finish in-house, then floated on a hat of US-sourced 6061-T6 aircraft-specification aluminum. Ten drive pins carry the braking load. For the owner who wants a rear disc that can be re-ringed cheaply between track weekends, this is the part GiroDisc built for these three cars.

Bolt-On and Go

GiroDisc describes the system as a direct replacement: it bolts straight to the car, works with the factory rear calipers and needs no modification. Once it is in place, only the cast iron ring is renewed when it wears, while the hat and hardware layout stay the same.

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.
