Kai Allen beat Zak Best to 2023 Super2 title by six points
The six-point margin was the third closest in Super2 history
Andrew Jones won on countback in 2004; Tony D'Alberto won by five points in 2007
Kai Allen's Dunlop Super2 Series victory was one for the record books, and not just because the 18-year-old became the youngest ever series champion.
Mount Gambier teen Allen clinched the Super2 title at the VAILO Adelaide 500 last month by a slender margin of six points after a hard-fought season.
Anderson Motorsport driver Zak Best led from Race 2 at March's Thrifty Newcastle 500 right up until Saturday's first race of the Adelaide weekend, before a penalty handed the lead to Allen.
Allen held on despite dropping to fifth behind Eggleston Motorsport teammate Cooper Murray in the closing laps of Race 2, with Best taking the chequered flag second.
The record books will show that only two seasons have been decided by a smaller margin than the six points that split Allen and Best, with the closest ever season not having a margin at all.
Andrew Jones and Luke Youlden ended the 2004 season tied on points, but the title went to Jones on a countback. Youlden had a two-point buffer heading into the final heat, and they finished level on 945 points.
A countback was required, and Jones won the trophy, thanks to his round victories at Winton and Eastern Creek, and two race wins. Youlden has been consistent, but had no round wins and a single race win.
Three years later, Tony D'Alberto beat Michael Caruso by five points, with the 2007 season featuring a unique, low-scoring points system. D'Alberto was ultra consistent, finishing 11 of the first 12 races of the season in the top three.
Caruso won six races to D'Alberto's two, but with points going down to 15th, non-scores in three races, including the first race of the Phillip Island finale, stunted his charge. D'Alberto wasn't without drama either, with a technical infringement seeing him disqualified from the final two races of the weekend.
The 2004, 2007 and 2023 seasons are the only seasons to date decided by a single-digit score. Dean Canto's two titles in 2000 and 2005 were won by just 31 and 30 points, with Adam Macrow hanging on to beat Shane Price by 40 points in 2006.
Macrow remarkably won the first five rounds of the season, before Price bolted home with five straight top three finishes.
The 2024 Dunlop Series will commence at the Thrifty Bathurst 500 on February 23-25.
