Which race cars use the GiroDisc Rear Rotors for Ferrari 296 and 488 Challenge Evo?

GiroDisc builds the Rear Rotors for Ferrari 296 and 488 Challenge Evo cars for two factory race cars: the 296 Challenge and the 488 Challenge fitted with the Evo rear brake upgrade. A 488 Challenge without the Evo rear upgrade uses a different rear rotor, so check the car before ordering.

Is this a carbon ceramic to iron conversion?

Yes. GiroDisc designed these rotors as direct replacements for the carbon ceramic rear rotors fitted to these Challenge cars. They work with the factory calipers, and no modifications are needed beyond the parts swap, though we confirm the complete parts list with each order.

How much does each Challenge Evo rear rotor weigh?

GiroDisc quotes about 24 lb per complete rotor assembly. The ring is 390mm in diameter and 32mm thick when new, with 72 curved vanes, and it sits on a 6061-T6 aluminum hat finished in a type 3 clear anodize to resist corrosion.

What is the wear limit on the Challenge Evo rear rings?

GiroDisc sets the minimum thickness at 30mm, against 32mm new. Replace the rings at that figure, or sooner if a crack forms that leads to the edge of the ring. The D2-285 ring set bolts to the existing hats, so only the iron is renewed.

Can the Challenge Evo rear rotors be serviced at the track?

Yes. Because the hat is reusable, a team can carry D2-285 ring sets as spares and swap rings onto the existing hats between sessions or events. The rings come with replacement hardware, and the spring clips and washers keep the floating mount quiet and secure.

GiroDisc Rear Rotors for Ferrari 296 and 488 Challenge Evo Iron Conversion

GiroDisc’s Rear Rotors for Ferrari 296 and 488 Challenge Evo race cars convert the factory carbon-ceramic rear discs to two-piece iron, for the 296 Challenge and for 488 Challenge cars fitted with the Evo rear brake upgrade. Each 390mm ring is 32mm thick and carries 72 curved vanes, and a complete assembly weighs about 24 lb on a 6061-T6 aluminum hat with a type 3 clear anodize finish. The factory calipers are retained. For a team that wants predictable iron wear and lower consumable costs across a Challenge season, it is a sound choice.

Fitment and Installation

The conversion works with the factory Challenge calipers and needs no modifications beyond the parts swap itself, so confirm the full conversion parts list with us before the car is booked in. Hats, rings and drive pins are made in-house by GiroDisc in Bellingham, Washington, and spring clips with spring washers give race-ready float without loose-hardware noise in the pit lane.

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.
