Honda Fit/Jazz Big Brake Kit Upgrade / TTSPORT Classic 5040S

Honda's Fit is a great little economy hatch, but the factory brake package is built for commuting, not for drivers who like to push the car. This case study looks at a Fit fitted with the TTSPORT TT5040S big brake kit — a straightforward OEM+ swap meant to give the car more braking capability without touching the wheels or suspension.

TTSPORT builds its calipers, rotors, pads, and brake fluid to the same standard, whichever kit you're looking at, so a small-car application like this one gets the same attention to fit and material quality as a bigger-brake sports car build.

Vehicle & Kit Specs

Why It Works

Most small economy cars, the Fit included, come from the factory with modest brake hardware — enough for everyday commuting but not built with much margin for repeated hard stops. A big brake kit addresses that from a few angles at once.

• A stiffer, higher-quality caliper flexes less under hard pedal pressure, which translates to a firmer, more predictable pedal feel instead of a spongy one.
• A performance rotor with better heat handling resists fade longer than the factory disc during repeated stops.
• Because the kit is designed to keep the car on its factory wheels, there's no need for spacers or a wheel change just to clear the new hardware.

Fitment Notes

The TT5040S kit on this Fit is built as a direct-fit upgrade — brake pads, brake fluid, and the mounting hardware needed for installation are included alongside the caliper and rotor, so the car goes from stock brakes to the TTSPORT setup without piecing together parts from multiple sources.
