Proformance Motorsport

4WD Trophy Truck - Off Road Racing 

Located in Perth Western Australia, Proformance Motorsport construct and race some of Australia's most advanced 4WD off road racing trucks.

 

Back in 1990 our "Imagineers" began creating our own Gearboxes, Differentials, Hubs, Spindles and Chassis for our personal use. With the exception of the engine and wheels almost all our components were hand made in our own premises to provide us exactly what we needed.

 

The components we manufactured have gained worldwide attention and after many requests from the Off Road Motorsport Communites around the world, team owner Scott Bryce finally decided to begin a business making and selling these unique components worldwide.
