Product Information

These GiroDisc 2-piece rotors are a direct replacement for the E46 M3 345mm rotor found on Competition Package (ZCP) and CSL models. Weighing in at 17.5 lbs per rotor versus 19 lbs per factory rotor, these fully floating assemblies help shed unsprung weight and rotating mass from the front axle of the vehicle.

The rotor rings are machined from a proprietary casting made of high-carbon iron formulated to GiroDisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 48 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The 2-piece design means a reusable hat which can be attached to new rings (part number D1-012) when they need to be replaced.

All major components including the hats, rotor rings, and drive pins are manufactured in-house at our facility in Bellingham, WA from domestically sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodize finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware.

Our E46 M3 rotors have been designed with common aftermarket caliper setups in mind, in addition to the stock sliding calipers available on ZCP and CSL cars. These setups can be used for aftermarket or upgraded caliper options.

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

The minimum thickness at which we recommend replacing these rings is 26mm. We also recommend replacing them if a crack leads to the edge of the ring.

Disc Brake Rotor

Commonly referred to as a Brake Disc or a Brake Rotor, these components play a vital role in your braking system. When applying the brake pedal, this produces hydraulic fluid pressure which then transfers the pressure from the pedal through your braking system and into your brake calipers. The caliper pistons then apply pressure against your brake pads squeezing them inward against your brake rotors ultimately causing friction and stopping the vehicle. Brake rotors are a regular maintenance item which requires either servicing by means of machine work, or most commonly replacement when they become too thin, pulsate, glaze, or grind from worn-out brake pads. It's recommended to replace the brake pads and rotors at the same time.

Disc Brake Rotor Failure Symptoms
  • Pulsating
  • Grinding
  • Squeaking
  • Glazing
  • Hot spots
  • A noticeable lip on the rotors outer edge
