This season has been as busy as ever at the Paradise Valley Speedway, but this weekend is the event many have been waiting for.
The TWS World Invitation Superstock Championship, also known as the World 240s, is the Rotorua Stockcar Club's premier event and this year's edition has attracted 103 drivers, including six from Great Britain.
Paradise Valley Speedway secretary Sonja Hickey said the event was first held in Palmerston North in 1987, but it had been Rotorua's baby since 2005.
"It needs to be a big enough track to host that many drivers and there's a lot of organisation that goes into it as well," Hickey said.
"The most drivers we've had at the event was 87 last year, so 103 is a big increase. It's the second largest gathering of superstocks that we've ever had in New Zealand."
She said there had been a resurgence in the superstock class in recent times, which contributed to the boom in numbers this year.
"Some of it is also [that] the New Zealand Superstock Champs were held in the South Island this year, in Christchurch. A lot of the North island drivers can't afford to go to that so they target this event instead."
The top three drivers from the New Zealand Champs, Jason Long (1NZ), of Hawke's Bay, Peter Rees (2NZ), of Gisborne, and Simon Joblin (3NZ), of Palmerston North, will be battling for top honours in Rotorua today and tomorrow.
Another one to watch is Great Britain's Frankie Wainman Jnr who has stood on the podium seven times at past events, including three wins.
"Of the Rotorua drivers, there's Bryce Steiner, who has been on the podium before, Lance Ashton is another one that's likely and there's Damian Orr and Dale Stewart. There are four or five that could easily do quite well," Hickey said.
Such hotly contested racing promised to provide a highly entertaining couple of nights for spectators.
"The vibe out there is terrific. I put a tag and share post up on our Facebook this week and in the first five hours it had 26,000 hits.
"It's going to be massive, I would be surprised if we didn't have more than 8000 people here on the second night."
Drivers are split into four groups and tonight they will race in three heats each. The top four from each progress to the finals night tomorrow , along with five of the overseas drivers who automatically qualify. Last year's first and second tier winners, Simon Joblin and Pat Westbury also pre-qualify for finals.
