Which cars use the GiroDisc Iron Conversion Rear Rotors?

GiroDisc lists the GiroDisc Iron Conversion Rear Rotors for every 987 generation Porsche Cayman and Boxster that came from the factory with Porsche Ceramic Composite Brakes. One pair covers the rear axle, and the rotors replace the factory carbon ceramic rear discs with iron.

Why convert a PCCB Cayman or Boxster to iron rear rotors?

Owners who use a PCCB car on track often prefer iron for its lower replacement cost. With the GiroDisc system in place, worn iron is renewed by fitting new rings to the existing aluminum hats instead of buying expensive carbon ceramic discs.

How is the iron ring fixed to the hat?

Ten high-strength alloy steel drive pins, made by GiroDisc to its own specification and cadmium plated, carry the braking load while allowing axial and radial float. Class 12.9 cap screws with hardened washers secure the pins to the aluminum hat.

Will the 987 rear conversion rattle when cold?

No. Anti-noise spring washers are mounted on the rotor side of each drive pin. They allow the iron ring to grow with heat expansion while removing the rattle normally associated with floating rotors, so the Cayman or Boxster stays quiet around town and in the paddock when the brakes are cold.

Is the 987 iron conversion sold for a single corner?

No. GiroDisc sells and prices these rotors as a pair, one left and one right, each labeled for its side of the car. The pair converts the complete rear axle of a PCCB-equipped Cayman or Boxster in a single job, so both rear corners run identical iron from the start.

Description

GiroDisc Iron Conversion Rear Rotors for 987 Porsche Cayman and Boxster with PCCB

GiroDisc’s Iron Conversion Rear Rotors are built for 987 Porsche Cayman and Boxster models that left the factory with Porsche Ceramic Composite Brakes. They replace the original rear discs with GiroDisc’s two-piece iron design: a cast iron ring poured in the USA and machined in-house, floated on ten drive pins from a hat of US-sourced 6061-T6 aircraft-specification aluminum. Owners who track a PCCB car and would like serviceable, replaceable iron at the rear axle, without touching the calipers, are the people this conversion was designed for.

Bolt-On and Go

GiroDisc describes the system as a direct replacement for the factory disc on every PCCB-equipped 987 Cayman and Boxster. Once it is in place, only the cast iron ring is replaced as it wears, and the aluminum hats and drive pin layout stay with the car.

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.
