CorkSport Mazdaspeed3 13 Inch Big Brake Kit

Even More Stopping Power for your Mazdaspeed 3

In our drive to make more power, we often forget about adding measures to keep us safe at the greater speeds we are achieving. The CorkSport Big Brake Caliper Kit is a great place to start, however if you wish you could stop even faster say hello to the CorkSport 13inch Big Brake Kit. Designed for serious stopping power, it includes 13” directional rotors, powder-coated 4-piston calipers, upgraded pads, and everything you need to install it on your Mazdaspeed3.

Read on for a breakdown of all the components

Rotors

The rotors have been designed to provide optimum stopping power while minimizing noise for street use. The upgrade to 13inch diameter rotors provides greater braking torque for an equivalent braking force (like how a longer wrench makes it easier to loosen a tight bolt). The larger diameter combined with an increased thickness of 28mm (vs 25mm for OE) provides better cooling as there is a larger mass to reject heat into.

In addition, slots were added to the friction surface to help sweep away any debris, brake dust, or gases that can otherwise affect your braking characteristics. We avoided drilling the rotors as holes decrease your total friction area and increase the chance that the rotor will crack. By moving to a two-piece design, we were able to decrease the overall weight of the rotor and by making the center section out of aluminum, it can help dissipate heat from the rest of the rotor better. Semi-Floating mounting between the inner and outer sections allows for quieter rotor vs having a full-floating center section.

Finally, the vanes in the rotor are atypical; these vanes are the “fins” that connect the inside and outside of the rotor. By using curved vanes instead of the typical straight vanes, the rotor becomes directional and has to be used on a specific side of the vehicle; however, it also provides more efficient cooling. When the rotor turns, the curved vanes draw air through the center of the rotor and out through the edge, providing greater airflow than a straight vane and thus better cooling. There is another bonus to heat dissipation as the curved vanes have a larger surface area that will come in contact with air than an equivalent number of straight vanes.

Calipers

Forged aluminum, four-piston performance calipers are included with the kit in a choice of powder-coated blue, red, or black.

Although each piston is individually smaller in diameter than the single OE caliper piston, the total surface area is increased so the braking force at a specific brake pressure is increased. Larger piston surface area means larger brake pads can be used as well. You also get more even braking force on each side of the rotor due to the opposed piston design. This encourages even pad wear, even rotor wear, and consistent braking characteristics.

The pistons themselves were specifically chosen for optimum braking endurance and reliability. They are staggered in size, with the pistons on the leading edge being slightly smaller than the trailing edge pistons. This is another protection for even pad wear. Each piston is made completely out of stainless steel for its low conductive heat transfer. What this means is that the pistons themselves will transfer less heat to the brake fluid than an aluminum or steel piston, decreasing the chances of overheated brake fluid.

Pads

Street performance brake pads are included with the kit that bridges the gap between Mazdaspeed3 street and track pads. They are larger and a more aggressive compound than the pads included with the CorkSport MS3 Big Brake Caliper Kit but are not a full track pad. They will produce less dust and noise than a track pad but still need to be warmed up for optimum performance. Should you need new pads or want to change to a different pad, you have a bunch of options from G-Lock, Carbotech, EBC, Hawk, and various other manufacturers.

Lines, Brackets, and Hardware

The rest of the CorkSport 13inch BBK is composed of exactly what you need to properly and safely install the kit on your Mazdaspeed3. Stainless steel brake lines are included to remove any risk of a soft brake pedal and ensure the calipers are operating optimally. High strength steel brackets properly position the four-piston calipers on the new rotors using the OE bracket locations. All components are locked down using Grade 12.9 hardware with a corrosion resistant coating for lasting durability.

The CorkSport Mazdaspeed 3 13” Big Brake Kit has everything you need to keep you safe at increased horsepower levels. If you’re looking for more than the stock brakes have to offer, let the CS Mazdaspeed3 BBK be a part of your build.

Mazda 3 Carnage

Last year we embarked on a new race car project: the Mazda 3. Our goal was to develop the car into a frontrunner in the T4 SCCA class and have a shot at the national title at the SCCA runoffs in 2016. Along the way, we’ve been making changes to the car and working on improving the setup, along with testing out products. One of the products we developed and built along the way was our Big Brake Kit (BBK). We never really explained why that kit was so important. So let me explain.

When Big Brakes Are Not Enough

Big Brake Kit | CorkSport

So you’ve installed your brand new big brake kit, and you’re thinking, “These really should keep me under control.” And maybe you’re even dreaming about being the latest, late-braking braker of all time in your run group. Well, before you start celebrating your newfound glory, there are three things you should consider.

Superior Stopping Power for your Mazda 3, Mazda 6 and Cx5 with our Big Brake Kit

After a long wait and a lot of testing, we’re proud to announce the launch of the CorkSport 4 Piston Big Brake Kit for the 2014+ Mazda 3 and Mazda 6, and the 2013+ Cx5.

Why upgrade your brakes to something of this level?

On our own 2015 Mazda 3 SCCA race car, we’ve found that even mildly increased power levels can burn up the stock brakes on the track. We melted the OEM dust boots off the stock calipers after two race weekends, which is not a good sign for longevity of OEM components.

CNC machined from extremely lightweight billet aluminum, the CorkSport calipers use an opposed piston design that is fixed to provide highly improved pad wear and caliper rigidity over the OEM design. At just over 7lbs, the aluminum CorkSport Big Brake Kit shaves almost 7lbs of unsprung weight off each corner of your Mazda 3, all while adding more stopping power and a much better pedal feel.

Available in 3 anodized colors, this brake system includes everything you need to easily upgrade your stock braking system including: high strength steel brackets, calipers, slotted brake rotors, stainless steel braided front brake lines, brake pads, and all necessary hardware.

The 2014+ Mazda 3 Big Brake Kit has the following features:

  • Superior Construction: Crafted from billet aluminum and made to last with durable components.
  • Longevity: With dual O-rings far away from the brake pads, these calipers are able to handle much more abuse than typical dust boot equipped calipers.
  • Lightweight: At just over 7lbs a side, this kit saves almost 7lbs of unsprung weight per corner!
  • Versatile: Designed around a popular brake pad style (Hawk #HB750), you can use almost any brake pad compound available on the market.
  • Available in Three Colors: Choose from black, red or blue in a durable anodized finish.
  • Ease of Use: With simple hand tools you can change brake pads in minutes and you are able to rebuild, so you can be back to factory fresh brakes in no time.
  • CorkSport Service and Support: Receive full color installation instructions, all of the needed installation hardware, and knowledgeable telephone support.
