OUR STORY

Prime Speedworks was built at the track, not in a boardroom.

With decades of real motorsport experience, we’ve gone fast across it all — V8 Supercars, Offshore Powerboats, Sprintcars, Midgets, and Drag Racing from Top Fuel to Super Sedan, including the brutal world of Drag-and-Drive.

We don’t chase hype — we back proven performance. Every product we support is chosen because it survives real racing, not because it looks good on a shelf.

If it doesn’t make you faster, stronger, or more reliable, it doesn’t belong at Prime Speedworks.
