Bouncing back the following weekend at Palmerston North he took out the second and third place. "Up till then I had found it hard to get in the top 10."
This result has him looking forward to his next fixture in Rotorua on December 27 and 28 - the North Island Championships, followed a couple of weeks later by the New Zealand championships in Stratford on January 8 and 9.
Iremonger said the Rotorua track in particular had been good to him at previous outings.
"It's a happy hunting ground - I have podiumed there before in stock cars and super stock best pairs, so am quite confident of a good finish."
When he's not in the driver's seat, something he got into when he was just 17 years old, Aaron is expanding his business of building stock cars for customers across New Zealand, and, more recently, fulfilling the niche role his company, Ironforce Race Cars, has developed in componentry.
His current car is one he built himself from scratch, beginning in June this year and putting in about 130 hours a week over four months to complete the turn key build.
The whole car is made out of high tensile plate BIZ 80 - all folded into box section shapes that require welding together, he says. "We built our own robot lineal welder to do this - there's no other way, as high tensile box section is not available in New Zealand."
His efforts, which took a lot of fine-tuning to get right, have resulted in a Nissan Quad Cam V8, 4 litre machine with revving up to 9000rpm.
On the end of the straights, it can reach 130km/hour.
