Knockhill provided the latest stop on the calendar for the TOCA support package this past weekend (12/13 August) and there were plenty of talking points to be dissected when the final chequered flag fell.
Despite the absence of the Renault UK Clio Cup and Michelin Ginetta GT4 Supercup, four championships made the trip north of the border with mixed conditions across both days providing high drama.
Arguably the biggest moment of the weekend came in the Porsche Carrera Cup GB. Double champion Daniel Cammish returned to the fray from Porsche Supercup duty and had his sights firmly set on closing the points advantage that had been built up over him by his rivals at Snetterton.
Taking pole position for race one, the Redline Racing driver produced a superlative display to take the chequered flag and quickly set about doubling up his tally in race two.
Embroiled in a captivating three-way fight for the lead with Charlie Eastwood and Dino Zamparelli in the closing stages, little did those watching know what was about to happen in the second 32-lap encounter.
As the three title protagonists battled for top spot, Cammish made his move for the lead on Eastwood at Clark corner. Switching his line to position himself on the inside of his team-mate, Cammish was squeezed off the circuit as Eastwood cut across, sending him into the barrier and ending his race on the spot.
That incident saw Eastwood retain his lead, holding station to take victory ahead of Zamparelli and Tom Oliphant. Following the race, Eastwood was given three points on his licence and a ten place grid penalty for the next race.
Harry King and Kiern Jewiss added their names to the list of race winners in the Simpson Race Products Ginetta Junior Championship as the battle in the points closed up.
King battled back from a tough opening lap in race one to produce a juggernaut-like display, picking those off in front of him at will. In race two, Jewiss finally took his long overdue maiden win and to further strengthen his stance as the dark horse in the title race.
Sebastian Priaulx and Tom Gamble both failed to make it to the top step of the podium and the top two in the points are now covered by just three markers.
The Protyre Motorsport Ginetta GT5 Challenge made a triumphant return to the TOCA package too, making an appearance for the second time this season.
Despite an array of talented racers littering the entry list, nobody was able to stop Geri Niscosia, who romped to a brace of victories.
In the British F4 Championship, Oscar Piastri continued his rich vein of form with another two wins to keep up the pressure on series leader Jamie Caroline. Staging an additional race due to one being postponed at Oulton Park earlier in the season, the single seaters were in high demand over both days.
Piastri held off the advances of Caroline in race one before the Pirtek Racing driver converted pole position in race two to dominant victory.
Oliver York wrote himself into history books as he claimed a maiden win in race three before Piastri rounded off the weekend in the same way he had started it, on the top step of the podium.
