Do the GiroDisc Front or Rear Replacement Rings fit both axles of a 360?

Yes. The GiroDisc Front or Rear Replacement Rings match the A1-001 rotor, which GiroDisc builds for both the front and rear of iron-braked 360 and F430 models. One pair renews one axle, so a full ring change on all four corners takes two pairs.

Can these Ferrari rings be fitted to factory rotor hats?

No. GiroDisc machines these rings only for its own hats from the A1-001 rotor. They are not designed for other brands or for factory two-piece hats, so the GiroDisc rotors must already be on the car before the rings can be used.

How thick are the 360 and F430 rings when new?

New rings measure 28mm thick on a 330mm diameter. GiroDisc recommends replacing them at 26mm, a figure marked on the hat and on the ring edge, or at once if a crack runs from the friction face out to the edge.

What hardware is supplied with the Ferrari rings?

Each pair comes with a full set of replacement drive pin hardware, including the cadmium-plated alloy steel pins, class 12.9 cap screws with hardened washers and the anti-noise spring washers. Only the existing GiroDisc aluminum hats are reused, so nothing else has to be sourced for the job.

Do the Ferrari rings have a rotation direction?

Yes. The curved vanes only pump air efficiently when they turn the intended way, so GiroDisc makes the rings left and right handed and labels each one. Fit each ring to the side marked on it when reassembling the rotors.

GiroDisc Front or Rear Replacement Rings for Ferrari 360 and F430

GiroDisc’s Front or Rear Replacement Rings restore a worn set of GiroDisc 360 and F430 rotors without buying new hats. The 330mm rings are 28mm thick with 48 curved vanes, and like the rotors they serve either axle, so the same part number covers front and rear service. GiroDisc casts them from its own high-carbon iron and supplies new drive pin hardware with each pair. A Ferrari owner who tracks the car and already runs GiroDisc A1-001 assemblies will find re-ringing the economical way to keep all four corners fresh.

Fitment and Installation

Remove the worn rings from the GiroDisc hats, fit the new rings with the supplied drive pins and cap screws, and tighten the screws to no more than 60 in-lb, or 7 Nm. The rings are left and right handed, so each one goes back on the side marked for it.

Features

330mm diameter, 28mm new thickness and 26mm wear limit
48 curved vanes pumping air outward from the hub
Usable on the front or rear axle
High-carbon iron poured in the USA

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.
