Drum brakes belong in a museum, not on your performance car. Our Rear Disc Conversion is the single most transformative braking upgrade for the Honda Fit/Jazz platform. This complete, direct bolt-on kit replaces the outdated and inefficient factory drums with a modern, high-performance disc brake system.
Say goodbye to brake fade on twisty roads and enjoy the consistent, reliable performance and firm pedal feel that only disc brakes can provide. This is the essential upgrade to properly balance a front big brake kit, complete the look behind your wheels, and unlock the true handling potential of your car.
The following data highlights the engineering behind this complete conversion. Note the specific caliper and rotor sizes, chosen to perfectly balance a front big brake kit without overpowering the rear axle. This kit is exclusively available with our high-carbon steel rotors and comes standard with our M-01 street performance brake pads.
