Championship Standings After Round 5

The final round of the Championship was going to be televised and the ACU made a highly controversial decision to change the Championship to a one-race event with the winner of the final round becoming the 1973 Champion.

Peter and Ron Hardy had led the Championship from Round 1 and could not be caught at the top of the table, leading by 17 points, so they had effectively already won the Championship with 1 Round to spare.

Round 6 - 28th October - Brands Hatch
