Do the GiroDisc Front Rotors for Honda S2000 fit without modification?

Yes. GiroDisc lists the GiroDisc Front Rotors for Honda S2000 as a direct replacement for the factory disc with no modifications necessary. They bolt directly to the car and work with the original front calipers, keeping factory brake bias and ABS efficiency.

Why not fit a big brake kit to the S2000 instead?

A big brake kit changes the caliper and often the front to rear balance, which can upset the ABS calibration. Upgrading only the discs keeps the brake bias Honda engineered while still adding a floating, curved-vane two-piece rotor to the front axle.

How many drive pins hold each S2000 ring?

Ten high-strength alloy steel drive pins, made by GiroDisc in the USA and cadmium plated for corrosion resistance. Class 12.9 cap screws with hardened washers secure them, and the pins carry the braking load while letting the ring float axially and radially.

Are the S2000 front rotors handed left and right?

Yes. The curved vanes run in one direction, so GiroDisc makes separate left and right rotors and labels each for its position. Fitting them to the labeled side keeps the vanes pumping air outward from the hub as designed for steady cooling.

What part number renews the S2000 front rings?

GiroDisc sells the S2000 front replacement rings as D1-104, in pairs with new mounting hardware. The aluminum hats are reused, and the rings are replaced at the minimum thickness marked on the hat and ring edge, or if a crack runs to the edge.

Description

GiroDisc Front Rotors for Honda S2000

GiroDisc’s Front Rotors for Honda S2000 roadsters swap the factory front discs for floating two-piece assemblies that bolt on with no modifications. The original calipers stay, so the S2000 keeps its factory brake bias and ABS efficiency. GiroDisc’s proprietary cast iron ring, poured in the USA and machined start to finish in-house, floats on a strictly US-sourced 6061-T6 aluminum hat through 10 cadmium-plated drive pins. For an S2000 driver who autocrosses or runs track days, it is a sensible upgrade that leaves the balance of the car alone.

Design and Performance

Curved vanes inside the ring act as a centrifugal pump, drawing air in at the hub and expelling it through the disc to manage heat in repeated hard stops. The slotted face clears the friction surface and prevents a water film. Anti-noise spring washers on the drive pins let the ring expand with heat and self-center, without the cold rattle common to floating rotors.

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.
