Open Classes

In September 2006 the “Radio Sport BMW Series” debuted at Pukekohe. Starting as one grid, this “open class” so to speak was made up of many different makes. From Colin Briscoe’s trusty E30, through to Gerry Hodges 635CSI, you could bring almost anything along.

Fast forward to today, and the Open Class is still very diverse. However instead of just the one “open” grid, the series has evolved to four different classes within, all with their own different rules and regulations.
