Australian Speedway Drivers and Riders
Association Incorporated


Australian Speedway Drivers and Riders Association Incorporated are pleased to announce that there will be a new level of speedcars available to the more budget minded competitor.
Engines will be readily sourced as stock block engines with the specifications outlined below.
These speedcars can compete with West Coast Speedcars without the restrictor fitted until such time as numbers build up to run a field on their own.
Expressions of interest are currently being sought and you can contact us at
