Does the GiroDisc Challenge Rear Iron Rotor Conversion fit a 488 Challenge Evo?

No. The Challenge Rear Iron Rotor Conversion covers the 458 Challenge and the 488 Challenge without the Evo rear brake upgrade. Cars carrying that upgrade need GiroDisc part A2-285, which is built for the 296 and 488 Challenge Evo rear brake.

How thick are the rear rings and when are they worn out?

The rear rings start at 34mm thick and GiroDisc recommends replacing them at a minimum of 32mm. They should also be replaced at once if a crack runs out to the edge. New rings are GiroDisc part D2-183, sold in pairs with hardware.

Are the factory Ferrari rear calipers retained?

Yes. GiroDisc designs the conversion around the factory rear calipers, and no modifications are required beyond swapping the rotors. That keeps the installation quick between events and avoids any change to the rear brake hydraulics, so the car stays as Ferrari built it.

What does each rear rotor weigh?

GiroDisc quotes about 24 lb for each complete rear rotor assembly, which includes the iron ring, the aluminum hat and the drive hardware. The figure is for the 380mm by 34mm rotor used on the 458 Challenge and the non-Evo 488 Challenge.

Why do GiroDisc rings use curved vanes instead of straight ones?

Curved vanes act like a centrifugal pump. As the rotor spins they draw cool air in at the hub and push it out through the ring, which carries heat away faster during long stints. That is why each rotor is handed for its side of the car.

GiroDisc Challenge Rear Iron Rotor Conversion for Ferrari 458 and 488

GiroDisc’s Challenge Rear Iron Rotor Conversion for the Ferrari 458 and 488 takes the rear axle off carbon ceramic and onto 380mm two-piece iron discs. The rings are 34mm thick with 72 curved vanes, cast from GiroDisc’s proprietary high-carbon iron and mounted to clear-anodized 6061-T6 aluminum hats. GiroDisc puts each complete assembly at about 24 lb. It covers the 458 Challenge and 488 Challenge cars without the Evo rear brake upgrade, and it is the natural partner to the A1-183 front conversion for teams that want one consistent brake material on both axles.

Fitment and Installation

The conversion is built for the factory rear calipers and needs no modifications outside the rotor change. Each rotor is handed and marked so the vanes turn the correct way. Cars with the Evo rear brake upgrade take a different GiroDisc rotor, so confirm the rear brake specification before ordering the Challenge Rear Iron Rotor Conversion.

380mm outer diameter with a 34mm thick ring
72 curved vanes that move air from hub to rim
6061-T6 aluminum hat in a type 3 clear anodize

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.
