In 1988, CAMS permit fees were higher for rallies that were a round of a “championship” than for non-championship rallies. To reduce the cost to organisers and ultimately competitors, the Victorian Trials Championship was consequently renamed the Victorian Trials Series. For consistency, we have continued to call it the VTC in most contexts!
