The annual trip north of the border to Knockhill for four TOCA support championships proved to be a blockbuster one as treacherous conditions spiced up the on-track thrills even further this past weekend (August 25/26).

As the season heads towards an enthralling climax, every point that is on offer is becoming ever-more pivotal and that proved to be plain to see as the undulating Fife circuit marked the latest stop on the calendar.

Last in action at Snetterton, the Porsche Carrera Cup GB contingent were back with Dan Harper emerging as the driver many were talking about come the end of the weekend. Storming to pole position on Saturday, the Scholarship winner then splashed his way to a second win of the season in race one.

Harper wasn’t to have things his own way as he had to fight his way back into the lead after making a small mistake earlier in the race. The Northern Irishman capitalised on an error at the hairpin made by Lewis Plato to retake a lead he would ultimately not lose again.

Race two would see George Gamble score victory, producing a controlled lights-to-flag performance however Harper was once again making a name for himself after producing a mesmerising drive to finish second. In the standings, a quiet weekend for points leader Dino Zamparelli has seen his series lead cut to just four points with Tio Ellinas hot on his heels.

Louis Foster was in unstoppable form in the Ginetta Junior Championship as he stormed to a brace of race wins. Picking up where he left off at Rockingham, the rookie held off title rivals Luke Browning and Adam Smalley to bring himself further into play in the title battle, closing to within 44 points of the standings summit.

Shane Stoney replicated Foster’s feat in the Protyre Motorsport Ginetta GT5 Challenge as he bagged two wins in contrasting conditions. Basking in the Scottish sunshine, Stoney made his way from sixth on the grid into the lead to pip Max Bird by little under half a second.

Heavy rain welcomed the GT5 Challenge drivers on Sunday but that didn’t stop Stoney from once again starring. Holding a host of lurid slides around the 1.27 mile circuit, Stoney held his nerve to fend off the advances of James Kellett in a nail-biting finish to take a clean sweep at Knockhill.

Rounding out the TOCA support championship action was a trio of races from the F4 British Championship certified by FIA – powered by Ford EcoBoost. Johnathan Hoggard proved to be the driver to beat as he bagged a brace of pole positions and then a brace of race wins.

Title protagonist Ayrton Simmons maintained his championship charge as he triumphed in race two.
