What does the GiroDisc 402mm Front Iron Rotor Conversion replace on the SLS AMG?

It replaces the factory carbon ceramic front discs. The GiroDisc 402mm Front Iron Rotor Conversion uses two-piece floating iron rotors on aluminum hats, which bolt in as a direct replacement for the original discs and are serviced later by renewing only the iron rings.

Why is the iron ring narrower than the ceramic disc it replaces?

GiroDisc deliberately uses a smaller swept band than the original ceramic rotor. Matching the full ceramic band in iron would make the rotor unnecessarily heavy, so the narrower ring keeps the weight at a sensible level for a car of this performance.

How many drive pins connect the SLS front ring to its hat?

Twelve. GiroDisc makes the high-strength alloy steel pins in the USA and cadmium plates them against corrosion. They carry the braking load while letting the ring float freely under hard track use, and class 12.9 cap screws with hardened washers secure each one to the hat.

Should anything else be checked before converting an SLS to iron rotors?

Yes. Contact Bulletproof Automotive before ordering so the complete list of parts for the conversion can be confirmed for your car. The rotors themselves are a direct replacement for the factory discs and bolt on without modification to the hubs or calipers.

What keeps a floating front rotor quiet on the SLS?

Anti-noise spring washers on the rotor side of each drive pin. They allow the ring to grow as it heats and to self-center, while removing the cold rattle associated with floating rotors, so the car stays civil on the street between track days.

Description

GiroDisc 402mm Front Iron Rotor Conversion for Mercedes-Benz SLS AMG

GiroDisc’s 402mm Front Iron Rotor Conversion moves a carbon ceramic Mercedes-Benz SLS AMG onto two-piece iron front rotors. GiroDisc floats its own cast iron ring, poured in the USA and machined in Bellingham, Washington, on a US-sourced 6061-T6 aluminum hat secured by 12 cadmium-plated drive pins. GiroDisc keeps the swept band narrower than the ceramic original so the iron rotor stays at a reasonable weight. For an SLS that is driven on track, iron rings that are renewed on reusable hats keep brake servicing simple and predictable.

Construction

Curved vanes inside the ring act as a centrifugal pump, forcing cooling air from the hub out through the disc during hard braking. The 12 drive pins carry the braking load while allowing axial and radial float, and class 12.9 cap screws with hardened washers secure them. Anti-noise spring washers let the ring grow with heat and self-center, yet keep it from rattling when cold.

About GiroDisc

GiroDisc designs, manufactures, and sells 2-piece, fully floating brake rotors for a wide range of performance vehicles. Every major component, including the hats, rotor rings, and drive pins, is manufactured in-house at their facility in Bellingham, Washington, from domestically sourced materials. GiroDisc rotors use a proprietary high-carbon iron ring formulated for superior metallurgy and thermal performance, paired with reusable machined-aluminum hats that reduce the long-term cost of maintaining a high-performance brake system. The 2-piece floating design sheds unsprung and rotating mass while remaining street-friendly, delivering race-proven braking for track and street use alike.

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.
