Honda Fit/Jazz Big Brake Kit Upgrade / TTSPORT Classic SP
The Honda Fit is one of the most popular small hatchbacks in China, prized for the "space magician" packaging Honda is known for, plus a strong modification following. But the stock floating calipers on a car this size have a ceiling. This owner found them adequate for daily driving, but noted they came up short during emergency braking, hard stops, and wet-road conditions — exactly the scenarios where confidence matters most. The fix was a TTSPORT Slim TT SP big brake kit.
The upgrade package: TTSPORT TT SP forged four-piston calipers, 278x24mm high-carbon heat-treated curved rotors, and TTSPORT stainless steel brake lines — all fitted behind the Fit's factory 15-inch wheels.

Why It Works
A forged, four-piston caliper flexes less than a stock single- or twin-piston floating unit under hard clamping load, which translates into a more direct, linear pedal instead of the soft, progressively mushy feel that shows up as pads and calipers heat up.
- Split forged four-piston design built specifically for small-wheel-size vehicles like the Fit
- 278x24mm curved rotor design helps manage heat buildup and reduce fade compared to a plain flat disc
- Fits behind the Fit's 15-inch factory wheels, no wheel swap needed for this install
Dust boots on the four-piston caliper also cut down on maintenance costs over time, while the stainless steel lines replace the factory rubber hoses to keep pedal travel firmer and more consistent under repeated braking.
