ECS Tuning M Performance Front & Rear Big Brake Kit - Blue

The best kind of upgrade is one that upgrades performance with aesthetics. By testing and in-house engineering, we were able to accomplish this task with an OEM+ twist - F30 M Performance big brakes for your E9X non-M. Careful machining and some thoughtful packaging allowed us to retrofit these beauties for a perfect fit. Offering improved brake torque, pedal feel, and braking response, this proprietary kit needs to be the go-to solution for your BMW. Our engineers were tasked with doing something that had never been done before - retrofitting F30 M Performance brakes onto an E9X non-M. The front was easy enough to make a reality, and we offer M Performance 4-piston Brembo calipers with our own ECS 2-piece rotors with a variety of pad options. The rear, on the other hand, required some careful decision-making and engineering, as the factory calipers are nowhere near a bolt-on option. The solution? Careful machining of the rear caliper combined with precisely designed, black zinc chromate plated, 4140 chromoly steel brackets, allowing us to include a 350mm rear rotor and the same wide range of pad options. Parking brake functionality is even retained on most cars - 128i and 328i will require fabrication to retain this functionality. The ECS M Performance Big Brake Kit includes: Performance: More on ECS Exact-Fit Stainless Steel Brake Lines (the same tried-and-true style you've probably been running for years): More on ECS 2 piece Cross-Drilled/Slotted Rotors:  ECS rotors have proven themselves to be robust, demonstrating excellent wear characteristics, no warping, no thermal stress cracking, no signs of hot spots and minimal pad glazing.​
