BMW Brake Rotors & Discs for BMW 3 Series E46 (1999-2005)

These 2-piece floating rotors help dissipate heat better than a standard cast iron rotor and are also lighter for less unsprung weight. Managing heat in the brake system is vital to braking performance, especially on the track or when driven hard. It's why your brake rotors have internal vanes that vent heat as the rotor spins. These 2-piece ECS rotors feature an outer cast iron friction surface ring that is separate from the aluminum center hat. This allows better airflow through the vanes and for the friction ring can expand as it gets hot. The rotors are also cross-drilled for better ventilation and slotted to improve brake pad performance.

ECS 2-Piece Rotors feature:

• Aluminum hats for light weight
• Heat-treated cast iron friction rings
• 2-piece assembly improves brake cooling
• Anti-corrosion coating on non-friction surfaces and hard anodizing on rotor hat

These are the same size as the stock rotors so your stock caliper and mounting bracket will fit and there will be no clearance issues with your wheels or to other components. Stainless steel rotor retaining screws are included. You can use these with any brake pad.

Price is for the pair of brake rotors.

This item fits the following BMWs:
2001-2006 E46 BMW M3 with CSL or ZCP brakes
2006-2008 E85 E86 BMW Z4 M Coupe Z4 M Roadster

GiroDisc presents its 2-piece rotors tailored for BMW's E46 M3 Competition Package (ZCP) and CSL models, providing a direct replacement for the stock 345mm rotors. These rotors redefine performance, weighing only 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. Featuring 48 curved vanes acting as a centrifugal pump, they draw air through the hub for optimal cooling even during intense usage.

The 2-piece construction allows for a reusable hat, offering ease of maintenance. Replacement is simplified by attaching new rings (part number D1-012) to the existing hat.

Each essential component, from the hats to the rotor rings and drive pins, is meticulously crafted in-house at GiroDisc's Bellingham, WA facility, using domestically sourced materials. The hat is made from 6061-T6 aluminum with a sleek black anodized coating, while the drive pins are crafted from a robust steel alloy and plated with cadmium for enhanced corrosion resistance.

These rotors seamlessly integrate with common aftermarket caliper setups and stock sliding calipers found on ZCP and CSL models, including compatibility with Brembo calipers from Porsche 996 and Megane RS swaps.

Specifications:

• Diameter: 345mm
• Thickness: 28mm
• Weight: 17.5 lbs per rotor assembly

With race-ready float ensured by spring clips and Belleville washers, these rotors deliver high performance on the track while maintaining street-friendly characteristics with no noise from loose hardware. Experience the pinnacle of braking excellence with GiroDisc's E46 M3 rotors.
