Pigdon only recently teamed up with Diamond Bay Motorsport and despite limited track time, has been very impressive in the W26 that was driven by for much of the season by South Australian Luke Dillon.
He won the final from Jason Kendrick, Brad Maiolo and Jamie Maiolo who collected enough points to win the season-ending mini-series.
Pigdon put himself in the best possible position from the start of the show, being the only driver to crack into the 12-second zone in qualifying.
He then took a second in his heat race and won the Top 8 Knockout series, to start from pole in the main event, on the inside of Carl Dowling who was the early leader and into lapped traffic after just three laps.
Five laps in Bradford got the #57 on its back wheels and lost a spot.
The race stopped on lap 12 when contact between Mitchell Wormall and Tim Van Ginneken saw the latter going over on the approach to the main straight.
There was a caution period after contact with Jake Beard-Miller and Robert Watson on lap 19.
On the restart Pigdon launched a challenge on Dowling but was unable to make it stick.
Unfortunately for Dowling it all came unstuck with nine laps remaining when he blew a left rear tyre on the back straight, and as he came to a stop, he was clipped at high-speed by Shaun Bradford who flipped hard.
The race was stopped again with four laps left after Robert Watson junior went into the pits bend.
On the race to the checkers Pigdon powered away for the win from Kendrick, who found a gap between the Maiolos to muscle from fourth to second in a spectacular move.
Brad Maiolo put in a stellar drive for his third after starting from P15 and earlier in the night dropped valuable points when the team was forced to change an engine.
Jamie Maiolo also dug deep after starting from P10 while Dillon started 14h and moved up to sixth.
Andrew Priolo yet again drove well at the business end of the night, this time coming from P17 to seven.
Kye Scroop (from P13) was eighth from Jason Pryde and Taylor Milling.
