KEY POINTS:
Earl Bamber made it three from three at Timaru's Levels Raceway this weekend and surged into the Toyota Racing Series points lead.
He took two wins on Sunday from a pair of pole positions - traditionally the less favoured starting line at Timaru as it is not the racing line and usually offers less grip.
The weekend's races started with a win in wet conditions on Saturday, where he started from the outside position and swept ahead of pole-sitter Andy Knight.
In cold, windy and dry conditions on Sunday Bamber was unstoppable.
He took a lead in the morning's 12-lap race and won without a strong challenge from second-placed Knight, who saw his championship points margin eroded to just three points.
The 20-lap Timaru Herald Trophy feature race sealed Bamber's championship lead. Off the start, Bamber led into the first corner, defending a determined charge by Knight. They were followed by Michael Burdett and Mitch Cunningham, the race order at the front of the field remaining the same for the first three laps.
