Will the GiroDisc 350mm Rear Rotors for 997 fit a Turbo that came with PCCB?

Yes. GiroDisc states that the GiroDisc 350mm Rear Rotors for 997 are a direct replacement on all 997 Turbo cars, both PCCB and non-PCCB equipped. A Turbo that left the factory with carbon-ceramic rear discs can run these iron two-piece rotors at the rear, as can a car on the standard iron brakes.

How do the drive pins locate the ring on the hat?

Ten high-strength alloy steel drive pins, made by GiroDisc in the USA and cadmium plated, take the braking load between ring and hat. They hold the ring in place while still allowing it to move axially and radially, so the iron can expand with heat without pulling the aluminum hat out of shape.

Can the rings on these rear rotors be replaced separately?

Yes. The aluminum hats are reusable and GiroDisc sells the rear rings separately as part number D2-032, in pairs with new mounting hardware. Once the rotors are installed, ongoing rear brake maintenance means replacing only the cast iron rings rather than the complete assembly.

Where are GiroDisc rear rotor rings made?

The rings are cast from proprietary high-carbon iron poured in the USA and machined from start to finish in house at GiroDisc in Bellingham, Washington. The hats are machined from US-sourced 6061-T6 aircraft specification aluminum, and the drive pins that join the two are also made by GiroDisc.

Do the left and right rear rotors differ?

Yes. GiroDisc rotors use curved internal vanes, so each disc is handed and must turn in the correct direction to pump air outward. Every rotor is labeled for its position, and fitting each one on the correct side keeps the vanes working as a centrifugal pump.

GiroDisc 350mm Rear Rotors for 997 Porsche 911 Turbo

GiroDisc’s 350mm Rear Rotors for 997 Porsche 911 Turbo cars cover every 997 Turbo, whether it left the factory on iron brakes or with PCCB carbon-ceramic discs, and GiroDisc lists them as a direct replacement for the original rear disc. The ring is GiroDisc’s own cast iron, poured in the USA and machined in Bellingham, Washington, floating on a hat of US-sourced 6061-T6 aluminum. For a Turbo owner weighing the cost of new ceramic discs, this is an iron rear setup made for repeated hard stops.

Construction

Ten high-strength alloy steel drive pins, made by GiroDisc in the USA and cadmium plated against corrosion, tie the ring to the hat while allowing axial and radial float. Class 12.9 cap screws with hardened washers secure the pins. Curved vanes inside the ring work as a centrifugal pump, drawing air in at the hub and pushing it out through the disc to shed heat.

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.
