Do the GiroDisc Toyota GR Corolla rear rotors fit the GR Yaris too?

Yes. The GiroDisc Toyota GR Corolla rear rotors are a direct-fit 316mm replacement for both the Toyota GR Corolla and GR Yaris, and include the caliper spacers and longer bolts needed to reposition the caliper.

Are any modifications required for the GiroDisc Toyota GR Corolla rear rotors?

No. The GiroDisc Toyota GR Corolla rear rotors are larger than the factory discs, but the included caliper spacers and longer caliper bolts handle the repositioning. No other modifications are necessary.

How much do the GiroDisc Toyota GR Corolla rear rotors weigh?

Each fully floating GiroDisc Toyota GR Corolla rear rotor assembly weighs 10.4 lbs, helping shed unsprung weight and rotating mass from the rear axle for sharper response and better heat management.

Can I buy just the replacement rings for the GiroDisc Toyota GR Corolla rear rotors?

Yes, but only once you own the complete assembly. The replacement rings (D2-268) reuse your existing hats and fit GiroDisc hats only, not OEM or other brands. Buy the complete GiroDisc Toyota GR Corolla rear rotors first, then replace only the rings as they wear.

When should the GiroDisc Toyota GR Corolla rear rotors be replaced?

Replace the rings on the GiroDisc Toyota GR Corolla rear rotors at a minimum thickness of 16mm, or sooner if a crack reaches the edge. Since the hats are reusable, you swap only the rings (D2-268) rather than the whole assembly.

Description

GiroDisc Rear 316mm Slotted Rotors for the 2023+ Toyota GR Corolla

Toyota GR Corolla rear rotors from GiroDisc are a 2-piece, fully floating slotted upgrade for the 2023-present GR Corolla. Larger than the factory discs at 316mm, each GiroDisc GR Corolla rear rotor assembly ships with the caliper spacers and longer caliper bolts needed to reposition the caliper, with no other modifications required. At just 10.4lbs per rotor, these fully floating assemblies shed unsprung weight and rotating mass from the rear axle for sharper response and better heat management. Sold and priced per pair as a complete rotor assembly.

Why the GiroDisc GR Corolla Rear Rotors?

The rings of the GiroDisc GR Corolla rear rotors are machined from a proprietary casting of high-carbon iron formulated to GiroDisc’s specifications. That superior metallurgy gives you a rotor that lasts longer under repeated hard stops, while the two-piece floating design cuts heat transfer to the hub and bearings. Spring clips and Belleville washers give the assembly true race-ready float while keeping it quiet on the street, with no rattle from loose hardware.

Cooling and Construction

The 48 curved internal vanes of the GiroDisc GR Corolla rear rotors act as a centrifugal pump, pulling air in through the hub to cool the rings effectively when the brakes are working hardest. The reusable hat is machined from 6061-T6 aluminum and finished in black anodize, while the drive pins are made from a high-strength steel alloy and cadmium-plated to resist corrosion. Hats, rings, and drive pins are all manufactured in-house in Bellingham, WA, from domestically sourced materials.

A Reusable Two-Piece Design

Because the hat of the GiroDisc GR Corolla rear rotors is reusable, you only replace the rings (GiroDisc part number D2-268) when they wear out, keeping long-term maintenance cost well below a full one-piece rotor. GiroDisc recommends replacing the rings at a minimum thickness of 16mm, or sooner if a crack reaches the edge of the ring. Note that GiroDisc replacement rings fit GiroDisc hats only, not OEM or other-brand hats, so the complete assembly must be purchased first.

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.
