Honda Civic (10th Gen) Big Brake Kit Upgrade / TTSPORT Classic 5440
The 10th-gen Honda Civic dropped its long-serving naturally aspirated R18 for a turbocharged 1.5T L15B8 — 130 kW and 220 Nm, still happy on 92-octane fuel. More power on tap without any change to the brakes is a familiar setup for a mushy pedal and rear rotors that look undersized behind the wheel. On this Civic, the owner addressed both at once: a TTSPORT Classic 5440 forged four-piston kit up front, and oversized 325mm rotors with stainless lines out back.
The car runs 17-inch wheels, which is right at TTSPORT's minimum recommended wheel size for the 5440 caliper — no spacers needed to clear the spokes.

The 5440's two-piece forged aluminum body bolts up through a vehicle-specific bracket, keeping the caliper radially mounted and centered over the 330mm rotor with no rework of the factory hub or knuckle.
Why It Works
- A forged, fixed four-piston caliper flexes far less under pedal load than the stock single-piston sliding caliper, so more of the pedal input goes into clamping force instead of caliper deflection — the pedal firms up.
- The 330x28mm front rotor and 325x10mm rear rotor both add rotor mass over the stock discs, giving the system more thermal capacity before fade sets in under repeated hard stops.
- With a recommended minimum wheel size of 17 inches and 86mm of spoke clearance, the 5440 tucks behind the Civic's factory wheels without spacers.
- Stainless steel lines on the rear resist the ballooning that rubber lines get under sustained pressure, keeping pedal feel consistent front to rear.
