With increased power comes great speed, and with great speed you need to STOP faster. If you’ve pushed the OE brakes found on your Civic SI, Sport, EX,LX or Honda Accord; then you quickly learned that the OE brakes are not up for the challenge.

At 27WON Performance we found the OE brakes to be a real issue and decided to develop our own Big Brake Kit for the 2016+ Honda Civic community. This kit we found also works great on the 2018+ Honda Accord.

The 27WON BBK combines forged calipers, two-piece rotors, billet steel brackets, stainless steel braided brake lines, and the hardware necessary for install into a complete package that is tested and proven on the track and the daily commute.


The braking system functions by converting rotational energy into thermal energy and is located on the un-sprung portion of the vehicle; therefore, braking performance is defined by heat dissipation, braking force, and weight. The 27WON Big Brake Kit was designed with these factors in mind to provide you with a complete BBK that outperforms the OE braking system, is durable & reliable, and looks great on your 2016+ Civic.


The forged calipers are coated in a durable and heat resistant hydraulic paint finish for long lasting vibrant color.

Currently offered in three color options:

  • Redline Red
  • Stealth Black
  • Signature Orange


The 27WON BBK utilizes a forged aluminum body with a stainless steel staggered 4-piston design to optimize the overall braking performance. Aluminum forgings are used for their superior weight to strength ratio to reduce overall un-sprung mass and reduce caliper flexing during aggressive braking.

This staggered stainless pistons are desinged to provide even pad wear.


The braking system functions by converting rotational energy (wheels rotating) into thermal energy (heat); controlling where the waste thermal energy goes is key to the peak performance and endurance of the braking system.

To reduce the rate of excess heat transfer into the brake fluid (reduced risk to boil fluid), stainless steel pistons are used vs the standard aluminum pistons due to stainless steel’s low thermal conductivity. By reducing the amount of heat transferred into the brake fluid, the 27WON BBK is able to perform far better and for a longer period of time vs the OE braking system.

  • The 27WON BBK is designed to be used with 17" inch or larger diameter wheels.
  • OE wheels will require the use of a wheel spacer for fitment over the 27WON BBK. Please use the Wheel Fitment Guide to determine how thick of a spacer is required.
  • Some aftermarket wheels will require the use of a wheel spacer for fitment over the 27WON BBK. Please use the Wheel Fitment Guide to determine how thick of a spacer is required.

The 27WON brake rotors use 2-piece construction to reduce the overall weight of the braking system, The rotor hat (center piece) is manufactured from aluminum and finished with a black protective coating. The rotor rings are where the major performance benefits come into play.

The 27WON BBK rotor rings increase the diameter to 13in (330mm) & thickness to 1.10in (28mm); this increase in overall size increases the total thermal capacity of the braking system and the braking force that can be applied to the vehicle.

Further improving the thermal capacity and cooling, the rotors feature directional internal vanes for more efficient cooling and rotor face slots to sweep away debris and brake pad gases that can build up during aggressive stopping.


No Big Brake Kit is complete without Stainless Steel Brake Lines, which is why 27WON includes DOT approved brake lines with every BBK. The included SS braided lines replace the OEM rubber lines to improve braking response and pedal feel and are designed to fit like OE.

To further complete the BBK, all necessary installation hardware and brackets are included. Billet steel black zinc brackets and class 12.9 hardware are also in every kit for a seamless install.


Despite the increased overall size and improved performance, the 27WON BBK weighs 6 lbs LESS (9.3% less) vs the SI OE braking system.

  • SI OE caliper per corner = 15.24lbs
  • SI OE rotor per corner = 17.08lbs
  • SI complete braking system = 64.64lbs
  • 27WON caliper per corner = 11.84lbs
  • 27WON rotor per corner = 17.48lbs
  • 27WON complete braking system = 58.64lbs

What can I say. Simply amazing both in build quality and stopping power. As well as being lighter than stock they are also quieter with far less 'squealing' that factory pads. A must buy for any FK7 owner. Thank you Vincent and the 27WON family!
This is a very high quality BBK. All of the hardware, brackets, lines, etc. are top notch. The calipers are absolutely gorgeous, and I cannot stop staring at them. This truly is a complete kit, they even include a small bottle of caliper touch up paint, which I would've never even thought of. The increased stopping power, coupled with lighter weight than the factory Civic Si brakes make for a much improved package overall. I can definitely recommend this kit for anybody who exceeds the factory braking capabilities. You won't regret buying this one!
