Suzuki Jimny Big Brake Kit Upgrade / TTSPORT Slim Series
The fourth-generation Suzuki Jimny is built for terrain that eats lesser small SUVs alive — but hold a steep downhill grade with nothing but the factory brake pedal, and you'll feel exactly where the stock system runs out of margin. TTSPORT built a vehicle-specific forged four-piston kit for the Jimny that bolts on behind the factory 15/16-inch wheels, no adapter bracket or spacers required.
The Jimny's body-on-frame construction and dependable four-wheel-drive system put it in the same conversation as far bigger off-roaders — Land Cruisers, Wranglers, G-Wagens. But descending a steep grade, the driver has only the brake pedal to manage speed, and that's a real stress test for a small SUV's stock brake hardware. A Japan-based customer asked TTSPORT to design a caliper that would fit the Jimny's OEM 15-inch wheels without touching the factory caliper mounting position — no bracket swap, no spacer. After months of development and testing, that kit is now shipping.

Why It Works
The stock caliper flexes under sustained pedal load, which is part of what makes the pedal feel soft on a long descent. TTSPORT's caliper body is forged as a single rigid unit, so more of the pedal pressure goes into clamping the rotor instead of deflecting the caliper — the result is a firmer, more linear pedal. Paired with the TT290x22mm vented rotor, the kit adds heat capacity over the factory solid disc, which helps keep that pedal feel consistent when the brakes are working continuously rather than just tapping and releasing.
- Forged four-piston caliper construction resists flex under sustained pedal load, translating to a firmer, more linear pedal feel than the stock caliper.
- The TT290x22mm rotor's larger swept area and vented design add heat capacity over the factory solid disc, cutting down fade on extended braking.
- Direct bolt-on geometry at the stock caliper location means the kit clears the factory 15/16-inch wheels with no spacers or bracket changes.
