Sharpen turn-in and maximize thermal efficiency on the street or track with ECS Tuning 2-Piece Front Brake Rotors for G-Chassis BMWs. Rooted in decades of BMW racing legacy, these high-performance 348x36mm rotors eliminate rotational inertia where it matters most
Featuring a motorsport-inspired 2-piece construction that pairs a heavy-duty gray cast iron friction surface with a 6061 aluminum top hat, each rotor shaves 5 lbs of unsprung mass compared to factory iron units (24 lbs vs. 29 lbs stock). That 10 lb total reduction across the front axle leads to better dampening, faster steering response on turn-in, and lighter acceleration. Held together with Grade 10.9 hardware and protected by a black anti-corrosion E-coat, these rotors are CAD-optimized to maintain strict clearance around OEM brake system geometry.
Features & Benefits:
2-piece design with aluminum top hats lower unsprung weight, dropping 5 lbs. from a stock rotor (Stock Rotor: 29lbs, ECS Rotor: 24lbs) Gray cast iron rotor ring construction dipped in black E-coat to provide corrosion resistance on non friction surface areas Lightweight yet durable 6061 Aluminum Grade 10.9 Hardware to secure rotor and top hat together Shape optimized to fit around OEM geometry, ensuring proper clearance from all other brake system components Kit Contents:
Semi-Floating Dimpled & Slotted Left Brake Rotor (348x36) Semi-Floating Dimpled & Slotted Right Brake Rotor (348x36) Stainless Brake Rotor Set Screws
