"The kids are all mates," says Roger, who has competitors as young as 6, including Sir Colin Giltrap's grandson.
"We also have older kids, teenagers, who do this on the weekend and it 100 per cent makes them better drivers," says Edwards. "It definitely works because they don't need to do it around the streets."
The club is 50 years old and has homegrown heroes such as Scott Dixon, Mitchell Evans and Scott McLaughlin, among many others, having passed through it.
"They all got their start in karting," says Edwards. "It's just the speed and thrill of it. Doesn't everyone want to ride them?"
Jordyn Wallace is one of the few girls racing today and her dad, Matt, helps with the mechanics and station. Matt started racing at the speedway when he was 15 then did circuit then karts, which he says is a bit of a backwards way to do things.
With no sons, his two daughters were bound to follow in his footsteps.
"I like going fast and beating the boys," says Jordyn, who owns a purple kart. "The more you drive, the better you get. Any girl can do it."
Matt says it costs around $4500 to get set up with the race suit, gloves, boots, helmet, neck brace (not compulsory, but highly recommended), and a second-hand cart. Then there's the station, which is from about $4000 to $20,000.
The kids are weighed in first, so each race is even. The karts are wheeled out, as if on tall stretchers, past the St John's Ambulance post. They're lined up low to the ground for the starting line.
There are plenty of smiles, despite the rain, but the tension on the faces in the line-up is also evident. They're a serious bunch right before the first lap.
"Look, he's just sitting there getting into the zone," says number one cadet finalist Ryan Crombie's mum, Angela. "He's quite focused since starting kart racing and has amazing upper body strength - he's always home-running in softball now."
Ryan has a quick pep talk with dad Greg, a car salesman, who takes him to races in Te Puke, Rotorua and Hamilton. Then they're off.
"The only downside is the drying out of the gear on a rainy day," says Angela as she wills her son to retain pole position with each lap, hoping he won't spin out in the rain.
"It's sometimes quite nervewracking to watch but I do like the smell and excitement of it and we've met some really nice families through it," says Angela.
"We're normally covered in black by the end."
After the race, children come out of the clubroom with buckets of hot chips smothered in sauce. Hot chips never taste as good as they do at a speedway and the kids bundle up their gear for the more sedate drive home, no doubt dreaming of their next thrilling kart race to come.
