Suzuki Jimny Big Brake Kit Upgrade / TTSPORT Slim Series
The Suzuki Jimny has earned a reputation as the miniature off-roader with a big personality — boxy, upright, and built on a body-on-frame chassis with part-time four-wheel drive. That rugged character deserves brakes to match. This case study follows a Jimny owner who swapped the factory front setup for a TTSPORT vehicle-specific forged four-piston big brake kit, built to fit behind the Jimny's stock 15-inch wheels.
The Jimny in this build runs the familiar 1.5L naturally aspirated four-cylinder — 75 kW and 130 Nm — paired with a 4-speed automatic and a part-time 4WD system. It's a light, capable platform, and the owner wanted a braking system with the same no-nonsense durability as the rest of the truck.

Why It Works
A forged caliper body is denser and stiffer than a cast one, which means less flex under pedal pressure and a firmer, more predictable feel at the pedal. The opposed four-piston layout clamps the pad evenly across its face instead of pushing from one side, so the pad wears flatter and bite stays consistent.
- Forged, opposed four-piston caliper for stable, consistent clamping force
- 290mm x 22mm one-piece rotor adds rotor mass and surface area over the stock disc, helping the system shed heat more effectively
- Slim, lightweight caliper profile designed to clear the Jimny's factory 15-inch wheels — no spacers required
- Stainless steel brake line for firmer, more consistent pedal response under repeated braking
The Jimny's boxy, angular lines already give it a hard-edged look, and the exposed four-piston caliper behind the wheel adds to that presence. But the real point of the swap is functional: a lighter, stiffer brake system that lets the driver brake with more confidence on trails and pavement alike.
