Besturn B50 Big Brake Kit Upgrade / TTSPORT Classic 9040
The Besturn B50 is FAW Besturn's first compact sedan, built on a Mazda-derived chassis with a double-wishbone front end and an E-type multi-link rear, both with stabilizer bars — a setup that's more capable than the car's modest reputation suggests. For this owner, the goal wasn't a faster car on paper, it was a car that actually stops the way it looks like it should. The fix: a TTSPORT TT9040 six-piston big brake kit up front, paired with a slotted two-piece rotor and stainless steel lines.
The owner picked the TT9040 six-piston kit and had the calipers finished in a custom blue to match the aftermarket wheels — a deliberate color match rather than a stock-color swap. TTSPORT's forged construction keeps the caliper body stiff under load, and the special coating on these calipers adds a layer of oxidation resistance, which helps protect the finish over time.

Why It Works
A forged six-piston caliper clamps down on the pads with less flex than the stock sliding caliper, which means pedal input translates more directly into clamping force instead of getting absorbed by a caliper body twisting under pressure. The two-piece rotor design separates the friction ring from the hat, which helps manage heat and keeps rotor mass in check compared to a solid one-piece disc.
- Six-piston forged caliper for a firmer, less flex-prone pedal feel
- Slotted two-piece rotor for heat management
- Stainless lines for a firmer, more consistent pedal under repeated stops
The real-world number backs it up: per an Autohome test, the stock B50 stopped from 100 km/h in 39.25 meters. After the TT9040 install, the owner measured a 5-8 meter reduction in stopping distance — enough to put this compact sedan ahead of plenty of stock sports cars in a straight-line stop.
