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.

The stock E46 M3 brakes measure in at 328mm and use a 1-peice rotor. While these are great for road use and even some occasional track days, someone looking for the best track set up should look to change their brakes out to the E46 M3 CSL style brakes. With just the addition of a pair of caliper carriers and a new set of 345mm floating 2-piece rotors, you can substantially improve your braking performance.

E46 M3 CSL/Competition brake rotors offer a number of advantages over the stock rotors. First, they are larger, moving the friction surface further away from the center, creating more surface area. This helps to alleviate heat soak issues that would be found on smaller rotors. Second, they have built in cooling designs that allow the rotors to cool down quicker in between braking. Cross drilling allows for better cooling as well as better pad contact by allowing gasses and break dust to pass through and directional veining improves cooling by forcing through and directing the air flow to reduce temperatures.

This CSL rotor conversion kit can be used with factory wheel sizes of 18" and larger and any E46 M3 brake pad set can be used.

Pagid's newest sprint racing pad was developed for racing cars achieving very high average speeds with short braking distances and functional aero. The RST pads feature very high friction levels for the quickest bite and highest fade resistance than any other Pagid pad. RST pads are broken into 5 levels and all have ranging bite and release characteristics. RST pads will trade low wear for torque output and faster response. These were developed based on the needs of race engineers in World Challenge, Daytona Prototype, and GTLM where functional aero meant high grip in the corners and smaller braking zones.

RST Brake Pad Types:

• RST1 -  Very high friction coefficient, high initial bite, progressive torque curve, very high fade resistant
• RST2 - Medium high friction coefficient, good initial bite, mild progressive torque curve, good pedal feel
• RST3 - High friction coefficient, good initial bite, low heat conductivity, excellent modulation and release characteristics
• RST4 - Medium friction coefficient, good initial bite, mild progressive torque curve, high heat tolerance with consistent feel
• RST5 - Optimum thermal management, absolutely fluid fade resistant, highly developed recovery properties, extremely high friction coefficient
