Description
Introducing GiroDisc's 2-piece rotors tailored specifically for the E46 M3 Competition Package (ZCP) and CSL models, directly replacing the stock 345mm rotors. These rotors redefine performance, boasting a weight of just 17.5 lbs per rotor compared to the factory 19 lbs, resulting in a significant reduction of unsprung weight and rotational mass at the front axle.
Crafted from a proprietary high-carbon iron casting to GiroDisc’s exacting standards, these rotor rings offer unparalleled durability. Their innovative design features 48 curved vanes that function as a centrifugal pump, drawing air in through the hub to ensure optimal cooling even during intense usage.
The 2-piece construction allows for a reusable hat, providing ease of maintenance. When replacement is needed, simply attach new rings (part number D1-012) to the existing hat.
Every essential component, from the hats to the rotor rings and drive pins, is meticulously crafted in-house at our Bellingham, WA facility, utilizing domestically sourced materials. The hat is constructed from 6061-T6 aluminum and finished with a sleek black anodized coating, while the drive pins are engineered from a robust steel alloy and plated with cadmium for enhanced corrosion resistance.
For seamless integration, our rotors accommodate common aftermarket caliper setups as well as the stock sliding calipers found on ZCP and CSL models. This includes compatibility with Brembo calipers from Porsche 996 and Megane RS swaps.
