However the team had to endure a tough run at the Hampton Downs 101, after an incident early in the weekend meant they had to sit out the remainder of the weekend.
"It was pretty hard to swallow the problems that we had at Hampton Downs," said Fillmore.
"[But] the disappointment of Hampton Downs, it happens. You look at the BMW next door to us, it happens in motor racing. But that's what makes these moments so good.
"To come back strong is a nice way to finish the season off."
The pair's weekend started with competing in the two final races of the Australian GT Championship's sprint season, finishing 22nd and 13th in the two races respectively.
They then put in a determined drive in the Highlands 101 event to outrace and outlast a number of more fancied teams and drivers to crack the top 10 - Craig Baird and Greg Murphy finishing first and second in their respective Australian entries.
"Our goal was to go and mix it up in the AGT sprint races. In the first race we had a bit of trouble with cars hitting us and bits and pieces, but then we came back strong in the second race," said Fillmore.
"Our goal was to try and get in the top 10 within the 101, which we did."
With New Zealand's endurance racing scene continuing to grow, Fillmore and Stutterd expect to be back again to defend their three respective titles in the new year.
"We're looking forward to doing it again, no doubt about it," added Stutterd.
