About us
Seventeen years Josh has been working as a mechanic in Bunbury’s performance scene, developing skills and a eye for perfection & detail working on-burnouts, show cars and countless custom builds has lead us to create “FLAWLS PERFORMANCE AUTOMOTIVE” people Its time Bunbury has a performance specialist! From dyno tuning and full forced‑induction projects to the daily family car, we treat every vehicle the same: meticulous, energetic and obsessed with results. Big budget blows or daily drivers—we give it our all.
Too many workshops treat cars like clock‑in jobs—poor communication, no accountability and spotty quality control. That’s not us. We treat every vehicle as if it were our own: clear communication, strict quality checks and full accountability on every job. No shortcuts. No corners. Just workmanship you can trust. We don’t stop when the lights go out. We’re constantly researching, testing and refining our methods—dyno sessions, new tech, better processes—so we can push performance further while keeping reliability rock solid. The result is measurable gains on the dyno and confidence on the road.
Our promise is simple
You’ll get our best every time. No half measures, no excuses, just passionate, precise work that performs. Come see the difference.
