Do the GiroDisc Murcielago Diablo front rotors require any modifications?

No. The GiroDisc Murcielago Diablo front rotors are a direct OE replacement that bolts straight to the car and works with the factory calipers with no modifications necessary, maintaining the factory brake bias and ABS efficiency.

How much lighter are the GiroDisc Murcielago Diablo front rotors?

Each GiroDisc Murcielago Diablo front rotor is approximately 24.5 lbs versus 27 lbs for the stock unit. That reduction in rotational and unsprung weight allows quicker acceleration and improved suspension response.

What is the difference between the 355mm and 380mm GiroDisc Murcielago front rotors?

The GiroDisc Murcielago Diablo front rotors (A1-098) are the 355mm setup for the Murcielago and Diablo, while the 380mm front rotors (A1-097) are for the '05+ Murcielago and require a caliper spacer. Confirm your front rotor diameter before ordering.

What are the GiroDisc Murcielago Diablo front rotors made of?

The GiroDisc Murcielago Diablo front rotors use a disc of GiroDisc's proprietary cast iron, poured in the USA and machined in-house, with a U.S.-sourced 6061-T6 aircraft-specification aluminum hat and a curved vane design that forces cooling air through the disc.

What happens when the GiroDisc Murcielago Diablo front rotor rings wear out?

Only the cast iron ring is replaced, not the full assembly. The aluminum hat is reused, making ongoing maintenance more cost-effective than replacing complete one-piece rotors.

GiroDisc Front 355mm Rotors for Lamborghini Murcielago and Diablo

Murcielago Diablo front rotors from GiroDisc are 2-piece, fully floating 355mm front rotors, a direct replacement for the OE disc on the Lamborghini Murcielago and Diablo with no modifications necessary. These GiroDisc Murcielago Diablo front rotors bolt directly to the car and work with the OE calipers, at approximately 24.5lbs per rotor versus 27lbs for the stock units. Upgrading with lightweight high-performance rotors rather than a big brake kit maintains the factory brake bias and ABS efficiency while cutting rotational and unsprung weight for quicker acceleration and suspension response. Sold and priced per pair.

Why the GiroDisc Murcielago Diablo Front Rotors?

Upgrading with the lightweight GiroDisc Murcielago Diablo front rotors rather than a big brake kit maintains the factory brake bias and ABS efficiency while cutting rotational and unsprung weight for quicker acceleration and sharper suspension response. The central hat is machined from strictly U.S.-sourced 6061-T6 aircraft-specification aluminum, while the disc is GiroDisc’s proprietary cast iron, poured in the USA and machined start to finish in-house. The curved-vane design, developed in racing, acts as a centrifugal pump, forcing cooling air through the disc under hard use.

Floating Mount and Construction

The rotor and hat of the GiroDisc Murcielago Diablo front rotors use a floating mount system with 10 high-strength alloy steel drive pins, manufactured by GiroDisc in the USA and cadmium-plated for long-lasting corrosion resistance. These pins take the braking load while maintaining axial and radial float between the hat and disc, secured by class 12.9 cap screws with hardened washers. Anti-noise spring washers on the rotor side let the rotor grow with heat expansion while eliminating floating-rotor rattle, and the float lets the rotor self-center between the pads.

A Reusable Two-Piece Design

Once the GiroDisc Murcielago Diablo front rotor system is in place, you simply replace the cast iron rotor ring when needed while reusing the aluminum hat, lowering the long-term cost of maintaining the brakes compared with replacing complete one-piece rotors.

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.
