BMW E46 300x22mm Front Brake Rotors - ECS Tuning 2-Piece Drilled & Slotted

Direct-fit 2-piece front rotors for E46, Z3 and Z4 models with 300x22mm hubs. Not a vague 'BMW upgrade' - these bolt straight on if your current rotors measure 300mm diameter and 22mm thickness.

• Semi-floating design - aluminium hat expands independently from the iron ring to resist warping under track-day heat
• Drilled and slotted - chamfered holes and ball-end slots clear pad gas and debris, improving wet-weather bite and pedal feel
• Lighter than stock - 3.6 lb saved per rotor cuts unsprung weight and rotational inertia
• Ready to fit - includes stainless ECS set screws; no rust-prone OEM fasteners to replace

Works with standard E46 calipers and pads. Confirmed fit for E46 323i/325i/328i/325xi (M52/M54), Z3 3.0i (M54), Z4 3.0i (M54/N52).
