ECS BMW Brakes & Brake Parts

These 2-piece floating rotors help dissipate heat better than a standard cast iron rotor and are also lighter for less unsprung weight. Managing heat in the brake system is vital to braking performance, especially on the track or when driven hard. It's why your brake rotors have internal vanes that vent heat as the rotor spins. These 2-piece ECS rotors feature an outer cast iron friction surface ring that is separate from the aluminum center hat. This allows better airflow through the vanes and for the friction ring can expand as it gets hot. The rotors are also cross-drilled for better ventilation and slotted to improve brake pad performance.

ECS 2-Piece Rotors feature:

• Aluminum hats for light weight
• Heat-treated cast iron friction rings
• 2-piece assembly improves brake cooling
• Anti-corrosion coating on non-friction surfaces and hard anodizing on rotor hat

These are the same size as the stock rotors so your stock caliper and mounting bracket will fit and there will be no clearance issues with your wheels or to other components. Stainless steel rotor retaining screws are included. You can use these with any brake pad.

Upgrade your BMW E9X non-M with an OEM+ twist - the F30 M Performance Big Brake Kit. Carefully engineered and retrofitted, these brakes offer improved brake torque, pedal feel, and braking response while enhancing the visual appeal of your vehicle. Designed to be the ultimate solution, this kit includes front and rear Brembo calipers, ECS 2-piece rotors, stainless steel brake lines, genuine BMW brake pads, mounting hardware, brake fluid, and pad wear sensors.

• Enhanced brake torque and pedal feel for improved braking performance
• Optimal balance (63.3% front, 36.7% rear) for the E9X chassis
• Improved cooling and heat management to reduce fade
• ECS Exact-Fit Stainless Steel Brake Lines ensure DOT compliance and minimal expansion under pressure
• ECS 2-piece Cross-Drilled/Slotted Rotors offer weight savings, increased thermal capacity, and improved cooling
• Rigorous testing ensures durability and superior performance in various conditions

Brake pad wear sensors are a convenient part of the braking system, notifying the driver of when the material on the brake pads are getting low and need to be serviced. Unfortunately it is common in custom or upgraded braking systems that the pad wear sensor is non-existent or does not mate properly with the connector on your vehicle, leaving you with a brake pad wear warning every time you start your vehicle.

ECS Tuning has developed this direct-fit Brake Pad Wear Sensor Bypass to alleviate this issue. This sensor bypass will trick the vehicle's electronics into thinking that the brake pads have adequate pad material to keep the dashboard warning from appearing. No more unnecessary warnings when installing a big brake kit or your own custom setup. This bypass is a plug-and-play component that requires no modifications so you can revert back to your OEM setup if necessary.

Some vehicles may be equipped with two front brake pad wear sensors, or a front and rear sensor, please be sure to double check the required quantity for your vehicle before placing an order.

*During installation, make sure to clean the mated female connector on your vehicle of any dirt or debris to ensure that the Brake Pad Wear Sensor Bypass is engaged securely.

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:

DOT-compliant kit to improve pedal feel in your vehicle.

ECS Exact-Fit stainless reinforced brake lines provide more confident and dependable stopping by maintaining consistent brake pressure, long lasting corrosion resistance, and increased protection from failure.

Even when new, factory style fabric mesh lined rubber hoses are prone to expansion under the pressure of hard braking, whether it be highway panic stops or threshold braking at the track. This expansion is even more prominent in aged and weathered rubber hoses. ECS Tuning's Exact-Fit lines are engineered and assembled with braided stainless steel mesh and offer superior expansion resistance and reinforcement. The resistance to expansion creates a firmer pedal, and a more direct pedal feel. The signature red polymer coating provides additional protection from the elements and abrasion common with the constant movement of suspension and braking systems.

ECS Exact-Fit brake lines are engineered to comply with DOT (U.S. Department of Transportation) FMVSS 106 standards. All lines are made on dedicated, DOT-compliant brake equipment and each is tested to 3000 psi before being shipped.
