Description

GiroDisc Front Slotted Rings for 2023+ Toyota GR Corolla

GR Corolla front rings from GiroDisc are 356mm replacement rotor rings (part number D1-268) for the front GiroDisc rotor assembly on the Toyota GR Corolla. Sold in pairs and supplied with fresh mounting hardware, these GR Corolla front rings let you refresh worn rings while reusing your existing GiroDisc aluminum hats, a more economical path than buying complete rotors again. They are the wear item for the two-piece GiroDisc front rotor, so you must already own the complete front rotor assembly (A1-268) before these rings can be used.

Why the GiroDisc GR Corolla Front Rings?

Each GR Corolla front ring is machined from a proprietary casting of high-carbon iron formulated to GiroDisc’s specifications, the same superior metallurgy used in the complete assemblies. Because the two-piece design keeps the aluminum hat separate and reusable, you only ever replace the wear item, the ring, keeping long-term brake maintenance costs well below a one-piece rotor. The slotted, curved-slot face provides consistent bite under hard use.

What You Get

The GR Corolla front rings ship as a pair with new mounting hardware, and the only parts you reuse are your existing GiroDisc hats. Unless specifically noted, GiroDisc replacement rings are designed to work with GiroDisc hats only; they are not compatible with other brands or with factory hats from cars fitted with OEM 2-piece rotors. You must already own the complete GiroDisc front rotor assembly (A1-268) before these rings can be used.

When to Replace

GiroDisc recommends replacing the GR Corolla front rings once they reach their minimum thickness, or sooner if a crack reaches the edge of the ring. Because the hats are reusable, a ring swap restores the assembly without the cost of a full rotor set.

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.
