Toyota Crown Big Brake Kit Upgrade / TTSPORT Classic 8703
The facelifted Toyota Crown ditched the old-man styling for something sharper and more youthful, built specifically for the Chinese market. But the drivetrain carried over unchanged — 193 hp at 6,200 rpm, 236 N·m at 4,400 rpm, paired with a 6-speed automated manual. Solid numbers, nothing flashy, and nothing wrong with them either. The brakes, though, were another story. This 2015 Crown owner wanted a pedal and a look to match the new face, so the car went in for a front brake upgrade behind its stock 19-inch wheels.
The finished setup pairs a gold caliper bracket with a silver TT8703 caliper — a color mix most owners wouldn't try on purpose. It works here. The GT6 piston layout gives the caliper a mechanical, purposeful look, and TT8703 has become a go-to brake upgrade for front-drive and all-wheel-drive platforms for exactly that combination: strong looks backed by real hardware.
Vehicle & Kit Specs

Why It Works
A forged monobloc caliper body doesn't flex under pressure the way a stamped stock caliper can, so more of the pedal input actually clamps the rotor instead of getting absorbed by caliper deflection. That's the difference between a mushy pedal and a firm one.
- Six-piston, GT6-layout caliper design for a firmer, more consistent pedal feel than the factory setup
- 380x32mm C-hook rotor design carries a higher friction coefficient than the stock disc, per the source, which helps braking performance directly
- Kit fits behind the Crown's factory 19-inch wheels with no wheel or spacer change needed
TTSPORT's C-hook rotor — sometimes called a crescent rotor — isn't just a styling choice over the factory disc. The scalloped edge increases surface friction against the pad, which the source notes gives a real assist to stopping performance on top of the visual upgrade.
