The factory front brakes on the Civic and Integra are built to handle everyday driving, but once you start asking more from the car, the limitations of a floating caliper setup become much easier to find.
The 27WON Front 4-Piston Caliper Upgrade Kit gives 2016+ Civic Base or Si and 2023+ Integra 1.5T owners a new way to step upbraking performance without replacing the entire front brake system. You get a pair of fixed 4-piston 27WON calipers, Blue Sport Street brake pads, caliper brackets, and the required mounting hardware while retaining your existing factory-size front rotors and factory brake hoses.
No new rotors. No new brake lines. Just the parts needed to move beyond the factory floating-caliper setupand put a more performance-focused caliper behind the wheel.
A complete Big Brake Kit is the right answerwhen you want to upgrade the entire front braking system, including rotor size and thermal capacity.But not every build needs to go that far. Maybe your current rotors are still in great shape. Maybe you already have replacement rotors you like. Or maybe you simply want to improve the caliper and pad package without paying for components you do not need. That is exactly what this kit was built to do.
The 27WON Front Caliper Upgrade retains the applicable factory-size front rotors and factory brake hoseswhilereplacingthe original front calipers with a fixed4-piston design. Thatkeeps the upgrade focused, reduces the number of parts being replaced, and creates a lower-cost pathinto a more performance-oriented front brake setup.
A brake upgrade should perform the part and look the part. Choose the anodized finish that best matches the rest of your build:
Sunset Orange
Metallic Crimson
Stealth Black
Both a full BBK and a caliper upgrade kit improve the factory braking system, but they are built for two different goals.
TheFront Caliper Upgrade Kitkeeps the factory-size rotors and factory brake hoses, while theFull Big Brake Kitreplaces the complete front braking package with larger 2-piece rotors, upgraded 27WON calipers using larger stainless staggered pistons finished in one of 3 painted colors and stainless steel brake lines.

Non-Si trimswill need to upgrade to larger Si (or A-Spec) specific brake rotors prior to installation of this caliper kit
Under extreme temperatures from overheating, the anodized finish on the caliper body may begin to fade. Take care to not use any harsh cleaners on the calipers to preserve finish
The 27WON BBK is designed to be used with 17" inch or larger diameter wheels. Several 18' OEM wheels do not require any spacer
A complete set of replacement brake pads options is listed at the bottom of this page
Minor tweaking of the brake rotor dust shields is required. Instructions included
We recommend replacing brake rotors when minimum thickness is reached per the Honda Factory Service Manual. If going back to your stock factory braking calipers after removal of this 4-piston kit, rotor replacement is recommended due to unswept area differences
The factory Civic and Integra front calipers use a floating design. In afloating caliper, the caliper body moves as the brake is applied. It is a simple and effective solution for a mass-production street car, butit is not the layout we would choose when performance is the priority.
The 27WON caliper uses a fixed 4-piston arrangement that applies braking force from both sides of the rotor. The caliper itself stays fixed in position while opposing pistons press the brake pads against the rotor.
For the driver, the goal is a more direct and confidence-inspiring brake response, more consistent pressure across the pad, and improved modulation when you are asking more from the brakes during spirited street driving.
Every kit includes a complete set of 27WON Blue Sport Street front brake pads designed for this specific 4-piston caliper.
The Sport Street compound is intended for the enthusiast who wants stronger, predictable braking performance while keeping the car friendly enough for normal street use. It is a great match for daily driving, weekend back-road runs, and other spirited street use.

Our 4-piston front brake upgrades are designed to be aftermarket-wheel friendly, but we recommend always checking wheel clearance before installation.
I like the OEM fit and the extra oil the pan holds with the upgraded baffle. I bought the pan for my wife's 1.5L MT hatchback since her pan was stripped. I was able to install it without having to turn the motor manually. The pan comes with a new drain bolt and o-rings. The only else that you need is the Hondabond and you can reuse the pan bolts.
