135/BMW Performance brakes for your E36 and E46! This kit uses the factory BMW Performance Brembo 6-piston calipers (same as 135i) with E46 330-sized rotors (325x25mm / 12.8") for a bolt on braking upgrade. Everything comes complete - 6-piston calipers, rotors, custom caliper bracket, brake lines, and a pad sensor. Choose your preferred brake fluid and brake pads below (or call us for a recommendation).

This is a direct fit to all E36 and E46 (not E46 M3) and comes with a lot more braking power than standard (especially on non-M E36). Consequently there will be more front brake bias - the front brakes have more bite than before. During normal street driving all you will notice is that the brakes feel stronger. For track driving we recommend a more aggressive rear pad to balance the brake bias or a StopTech or Brembo big brake kit that has been properly engineered for the chassis (not a retrofit).
Requires 17" wheels and wheel spacers may be required depending on wheel spoke design. E46 Style 68 wheels shown are used with 5mm spacer.
Upgrade your BMW's braking performance with the ECS Big Brake Kit, designed to deliver enhanced stopping power and reduced brake fade. This comprehensive kit includes 6-piston calipers from the E82, E88, and the E9X BMW Performance big brake kit, along with original equipment pads for optimal braking efficiency. The package also incorporates 325x25 ECS 2-piece rotors, ECS caliper brackets, Exact Fit braided stainless reinforced brake lines, essential hardware, and one liter of Pentosin Super DOT4 Brake Fluid.
Key Benefits:
The ECS Big Brake Kit ensures that brake bias remains stable, making it suitable for various applications. For track use, consider pairing with a more aggressive rear pad. These calipers are compatible with most 17” wheels; however, please refer to the attached template for fitment verification. Additionally, follow the attached installation guide for replacing the OEM caliper carrier with the ECS caliper carrier.
E46 M3 CSL brakes fit the E36 M3 for a bolt-on size enhancement and more stopping power. The CSL rotors are a full 30mm (1.18") larger than the stock E36 M3 discs. The larger rotor puts out more braking torque and can handle more friction and heat than stock. With the special brackets these larger rotors are able to bolt-on to the E36 M3 hub using your original calipers and lines. Simply bolt them on using the new caliper bracket. The E36 M3 CSL upgrade is a moderate upgrade over stock compared to a StopTech or Brembo Big Brake Kit but has lower upfront cost, lower consumable cost (pads and rotors), and has a wide range of pad choices (any brake pad for an E36 M3 or E46 M3 will work).
We offer these brakes with three rotor choices -
With more braking torque, the brake bias is changed. For the street, you will notice more stopping power and more "bite" from the front brakes. You may not notice the front brakes are working harder. If you're using this kit on the track it will be more important to balance the brake bias using different front-rear pad compounds. The front brakes will be doing more work than before to slow the car down and you will need to balance that with a more aggressive pad on the rear. You may notice the front tires locking up sooner, especially in wet conditions. Contact us to discuss track pads for your situation.
Wheel fitment: 18" wheels are strongly recommended for brake clearance although some 17" wheels will work (if they clear a BBK they will work with these)

As an E9X M3 owner, do you feel short-changed in the braking department? The next gen M3/M4 got serious Brembo calipers. With a special bracket the front 6-piston calipers can fit the E9X M3 for a bolt-on caliper and rotor upgrade. The rotors in this kit are 382x36mm - 22mm larger and 6mm thicker than the stock E9X rotor (and slightly bigger than the stock M3/M4 disc). The larger front rotors will help manage and dissipate heat better than the smaller stock rotors. And a larger rotor and caliper mean stronger brakes. Testing has shown the brake bias is very close to a stock E9X M3. Upgraded rear rotors are also included to work with the stock rear calipers. These are the blue M3/M4 calipers with the ///M logo.
