Two races wins and the demise of his main rivals has elevated 17-year-old AJ Lauder to a healthy 195 point lead after the weekend's fourth round of the Suzuki Swift Sport Cup held near Timaru.
The final South Island race for the 2011/2012 season, Lauder headed off Karaka's Andrew Vincent and Hamilton's Shaun Lawrence, who finished second and third respectively for the round.
"I've had a good run in the South Island and leave with a better lead than I could have hoped for," said Lauder.
"It all played our way as a few people went off, even in the final race where I was happy to sit in second, but managed to get the advantage around the big sweeper."
Winning the Saturday afternoon race Lauder tip-toed around Timaru's 2.4km circuit during this morning's reverse-grid ten-lapper when heavy rain made for skating rink like conditions. Finishing sixth, behind winner Shaun Lawrence (Hamilton), it was the loss of Rangiora's Chris Cox that reinforced Lauder's championship position.
