Which car are the GiroDisc Front Rotors for Maserati MC20 made for?

GiroDisc lists the GiroDisc Front Rotors for Maserati MC20 for the front axle of the Maserati MC20. Because brake specifications can vary between cars, contact Bulletproof Automotive with your vehicle details before ordering so the fitment can be confirmed against your car.

Why choose a two-piece floating rotor for the MC20?

The floating ring can expand with heat independently of the aluminum hat, and when it wears only the ring needs replacing while the hat stays in service. GiroDisc two-piece rotors also generally weigh less than the factory discs they replace.

Do the MC20 rotors make noise from the floating hardware?

No. Anti-noise spring washers on the rotor side of each drive pin let the ring grow with heat while eliminating the cold rattle floating rotors can produce. The cap screws may look slightly loose, and GiroDisc never tightens them beyond the specified torque.

When should the MC20 front rings be replaced?

Replace the rings once they reach the minimum thickness marked on the hat and the edge of the ring, or straight away if a crack reaches the edge. The aluminum hats can then be reused with a new pair of GiroDisc rings.

Description

GiroDisc Front Rotors for Maserati MC20

GiroDisc’s Front Rotors for Maserati MC20 bring the company’s two-piece, fully floating design to the front axle of Maserati’s mid-engine coupe. GiroDisc machines the hat from 6061-T6 aircraft-specification aluminum and pairs it with a ring cast from its proprietary high-carbon iron, poured in the USA and machined in-house in Bellingham, Washington. The ring rides on cadmium-plated alloy steel drive pins that GiroDisc makes itself. For an MC20 owner who wants a serviceable iron front rotor with a reusable hat, it brings GiroDisc’s racing-derived construction to a road car.

Construction

Curved internal vanes act as a centrifugal pump, forcing air from the hub out through the disc, while slots clean the friction surface and prevent a water film. Anti-noise spring washers on the drive pins let the ring grow with heat and self-center without the cold rattle associated with floating rotors. Cap screws are class 12.9 with hardened washers and are never tightened beyond 60 in-lb, or 7 Nm.

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.
