Honda Civic (10th Gen) Big Brake Kit Upgrade / TTSPORT Classic 8703
The 10th-gen Honda Civic built its reputation as a hot-hatch-adjacent sedan on the strength of its 1.5T engine and eager chassis, but the factory brakes were never sized for spirited driving. This car's owner swapped in a TTSPORT TT8703 six-piston big brake kit to match the pedal to the performance the car already had.
China's domestic-market Civic comes with a choice of 1.0T or 1.5T turbo engines, the 1.5T making 177 PS and 220 Nm through a 6-speed manual or CVT. That's enough performance potential that plenty of owners push the car hard, on street and track alike — and the stock brake package quickly runs out of margin when they do.

Why It Works
- The TT8703 caliper is cast as a single piece, which cuts down on the self-flexing that a bolted-together caliper body can suffer under hard clamping loads — that rigidity is what keeps pedal travel consistent lap after lap.
- Different piston sizes across the caliper bore even out clamping pressure on the pad surface, giving a more linear pedal feel and helping the pad wear evenly instead of tapering off on one edge.
- Steel pistons hold up to sustained heat better than lighter alternatives, which matters once the pads and fluid start working hard.
- The 355x32mm drilled rotor adds rotor mass and surface area over the stock disc, giving the system more thermal capacity to shed heat and resist fade during repeated stops.
The owner reported that after the swap, the brakes felt more responsive with a noticeably shorter stopping distance — a meaningful improvement for daily driving confidence, not just track days.
