13 inch Big Brake Kit for 2007-2013 Mazdaspeed 3 and 2004-2013 Mazda 3

The CorkSport Advantage

Performance Advantage

Everything in this kit was carefully chosen to bring the best braking performance possible to your Mazdaspeed3. Brake performance is defined by heat, weight, and force. Each component was chosen specifically for its effect on one of these characteristics to bring together a kit that will bring your Speed3 to a stop just as fast as it accelerates. After all, chasing a ton of power gets dangerous really quick when you can’t slow down!

Upgraded Rotors

Performance two-piece 13” (330mm) brake rotors are included with the kit. They are 10mm larger in diameter to produce a greater braking torque at an equivalent braking force (the same way a longer wrench makes it easier to loosen a bolt). More consistent brake force is achieved through the slots in the rotors. They sweep away dust, gases, and other debris that may otherwise affect braking performance. The larger diameter of the rotors combined with rotor thickness upgraded to 28mm means more mass to reject heat into. This heat is then dissipated easier through the specially designed vanes in the rotors. The vanes are the “fins” that connect the inside and outside of the rotor. Making them curved allows for better airflow through the rotor and thus better cooling. Lastly, the rotors are two-piece with an aluminum rotor hat for weight saving and improved heat dissipation.

Four-Piston Calipers

The aluminum four-piston calipers included with this kit are a further upgrade from the CorkSport Big Brake Caliper Kit. The four pistons are individually smaller than the single OE piston; however, the total surface area is increased, providing more braking force from the same amount of braking pressure. By moving to two pistons on either side of the rotor, pad size is maximized and braking force is evenly distributed on the pad on either side of the rotor. The four pistons are staggered in size to ensure even pad wear. Each piston is also made of stainless steel instead of aluminum or even regular steel as stainless steel has lower conductive heat transfer. This means less heat is transferred to your brake fluid, reducing the chance of boiling it. Finally, the calipers are powder-coated blue, red, or black to keep them looking good and matching your personal Mazdaspeed 3 style.

Performance Brake Pads

Brake pads included with the CorkSport 13” BBK is a larger and more aggressive compound than OEM pads and even the pads included in the Big Brake Caliper Kit. They bridge the gap between a street pad and a full trackpad to provide good performance on the track without a huge amount of dust and noise when driven on the street. As an added bonus, when you eventually need to replace the pads, you have a myriad of options as they are common-style brake pads.

Hardware, Brackets, and Lines

Everything needed to install the CorkSport 13” BBK onto your MS3 is included in the kit. High-strength steel caliper brackets position the new calipers in the correct location while braided stainless steel brake lines ensure you have no issues with a soft pedal. The kit is tied together with grade 12.9 corrosion-resistant hardware to ensure everything stays securely mounted. The use of a wheel spacer is required for OE wheels and some aftermarket wheels.
