Despite the disappointment of not placing in the top three or winning, Tarrant said the team had a good weekend.
"We won our first qualifying race against the Manawatu Mustangs but also lost Mike McLachlan for the weekend after his car was badly damaged," he said.
Tarrant said they initially won their second race against the Auckland Allstars.
"It was a brutal race with plenty of action – which put us into the semifinals," he said, "but a protest was put in for an infringement Quinn Ryan did so the win was taken away from us."
They were then subsequently placed into the second tier races for night two.
The 27-year-old driver said their first race on night two of the competition against the Gisborne Giants was always going to be tough.
"Unfortunately we lost 98B Quinten Butcher early so we were three against four and Gisborne got the win," he added.
Thousands of speedway fans travelled to Palmerston North in support of their local teams in the championship's 41st competition.
A total of 16,000 tickets were sold to the biggest event in the SuperStock calendar.
