GiroDisc 01-06 BMW M3 (E46 w/Competition Package & 345mm Front Rotors) Slotted Front Rings

The GiroDisc Slotted Front Replacement Rings for the 2001-2006 BMW M3 (E46) with Competition Package and 345mm Front Rotors are engineered to deliver top-tier braking performance for demanding driving environments. Manufactured from premium high-carbon iron, these rings provide excellent thermal conductivity and resistance to wear, helping to prevent brake fade during intense track sessions or spirited street driving. The precision-machined slotted design improves pad cleaning and gas evacuation, ensuring consistent pad contact and enhanced braking responsiveness.

These replacement rings are designed to fit perfectly with GiroDisc’s lightweight aluminum hats, significantly reducing unsprung weight and rotational mass for sharper handling and quicker brake response. Featuring a floating mount system, the rings allow for thermal expansion without warping or noise, delivering race-grade durability while maintaining smooth operation and comfort for everyday driving. This bolt-on solution offers an effective way to renew braking performance and extend the life of your E46 M3’s front braking system without replacing the entire rotor assembly.
