What is the benefit of moving a Roma to iron front rotors?

Iron rings are durable, wear predictably and cost much less to renew than exotic disc materials. On the GiroDisc two-piece design only the iron ring is replaced when it wears, while the aluminum hat stays in service, which keeps long term running costs sensible.

How do the curved vanes cool the front brakes?

The vanes inside each ring are curved so that, as the rotor turns, they pull air in at the hub and throw it out through the rim like a centrifugal pump. Each rotor is handed left or right so the vanes always turn in the correct direction.

Why are the rotors slotted rather than drilled?

GiroDisc uses slots to keep the friction surface clean and prevent a water film forming in the rain. It does not recommend drilled discs for performance use, since the holes can lead to cracking after repeated heat cycles. Slots deliver the cleaning benefit without that risk.

What maintenance do the front rotors need?

Check ring thickness against the minimum marked on the hat and the ring edge at each brake service, and replace the rings at that figure or if a crack reaches the edge. Keep the cap screws at or below 60 in-lb and leave the float alone.

Description

GiroDisc Portofino and Roma Front Iron Rotor Conversion for Ferrari

GiroDisc’s Portofino and Roma Front Iron Rotor Conversion moves the front axle of these front-engined Ferrari grand tourers onto two-piece, fully floating iron discs. The rings are cast from GiroDisc’s proprietary high-carbon iron, poured in the USA and machined in Bellingham, Washington, and each one floats on a hat of 6061-T6 aircraft-specification aluminum. Drive pins made by GiroDisc in high-strength alloy steel carry the load. For an owner who wants a brake that is straightforward and affordable to service over years of spirited driving, iron is the pragmatic choice.

Design and Performance

Curved vanes inside each ring act as a centrifugal pump, drawing air in at the hub and forcing it out through the disc to control temperature. Anti-noise spring washers on the cadmium-plated drive pins let the ring expand with heat while preventing the cold rattle of a floating rotor. A slotted face keeps the friction surface clean and clears water in the wet.

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.
