Honda Fit/Jazz (GK5) Big Brake Kit Upgrade / TTSPORT Direct-Mount Series
A Front Brake Upgrade for the Honda Fit GK5
The third-generation Honda Fit (GK5) is a small car with a genuinely global following, but its stock front brakes are sized for everyday commuting, not spirited driving. This install case swaps in a TTSPORT front kit built specifically for the GK5: a larger four-piston caliper matched with a 285mm one-piece rotor, aimed at eliminating brake fade and giving the pedal a firmer, more confidence-inspiring feel.
The kit was built around the GK5's front axle geometry, so the caliper and rotor combination bolts in without spacers or other workarounds. The rotor is a one-piece (non-floating) design finished at 285x20mm.

Why It Works
A four-piston caliper spreads clamping force across more pad area than the stock unit, which means more consistent friction and less flex under hard braking. Pairing it with a larger 285mm rotor adds thermal mass, so the system sheds heat more effectively and resists fade during repeated stops.
- Larger rotor diameter (285mm vs. stock) increases swept area and heat capacity, reducing fade under repeated braking.
- Four-piston clamping distributes pressure more evenly across the pad than a stock single- or dual-piston design, improving pedal feel.
- The rotor and caliper are matched to the GK5's factory mounting geometry, so the installer reported no vibration and no need for spacers.
