Description

GiroDisc Slotted Rear Brake Rotors with Spacers for 981 / 982 Porsche Boxster Spyder, 718 Boxster and Cayman GTS 4.0 [A2-049B]

GiroDisc manufactures the central hat section of its rotors using U.S.-sourced 6061-T6 aircraft-grade aluminum. The disc component is crafted from GiroDisc’s proprietary cast iron, poured in the USA and fully machined in-house. Designed with a curved vane configuration, the rotor acts as a centrifugal pump, channeling cooling air through the disc — a design originally developed for racing applications. The rotor and hat are connected using a floating mount system featuring 10 high-strength alloy steel drive pins. These pins, produced by GiroDisc in the USA to precise specifications, are cadmium-plated for enhanced corrosion resistance. They bear the braking load while preserving axial and radial float between the hat and disc. Secured by class 12.9 cap screws and hardened washers, the pins are equipped with anti-noise spring washers on the rotor side. This design mitigates noise during cold operation while accommodating thermal expansion and enabling the rotor to self-center between brake pads.

About GiroDisc

Brake rotors have long been an underappreciated component in performance car braking systems. Traditional one-piece rotors are heavy, retain heat, and reduce braking efficiency while increasing unsprung weight, which negatively impacts handling. Founded in 2003, GiroDisc set out to revolutionize this area by designing and manufacturing two-piece brake rotors engineered to perform flawlessly under extreme conditions. GiroDisc’s fully floating design utilizes tension hardware to ensure silent operation on the street while delivering track-ready performance. By focusing exclusively on this specialized niche, GiroDisc has advanced its engineering and manufacturing processes to industry-leading standards. Enthusiasts worldwide have enhanced their existing brake systems with GiroDisc rotors, often avoiding the expense and complexity of a big brake kit upgrade. Based in Bellingham, Washington, GiroDisc handles every aspect of production — from design and engineering to manufacturing and fulfillment—on site. For more information about GiroDisc products and services, please reach out directly.

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.
