“We’ve done a three-year term for Sandown with [circuit owners] the Melbourne Racing Club which includes the requisite safety upgrades,” he said.
The safety changes include modifications to the run-off at the notorious, high-speed Turn 6, which will be completed ahead of this year’s Penrite Oil Sandown 500 on November 10.
Seamer confirmed the option of running 2x250km, single-driver races from 2020 to keep the Sandown 500 nameplate had been looked at, but ultimately opted against.
“We had a lot of debate about that but it would have just put us too far over on the kilometres [for the season],” he said.
The 500km format’s move from Sandown to The Bend ensures a PIRTEK Enduro Cup round before the Supercheap Auto Bathurst 1000.
Bathurst has become the opener this year after the Sandown 500 was moved to November, swapping places with the ITM Auckland SuperSprint.
The move aimed to increase the chances of fine weather for the Sandown 500, and avoid clashing with AFL finals in Melbourne.
“You can split opinion about this year, some people love the excitement that Bathurst is going to be the opener and other people hate it,” said Seamer.
“But the reality was that we were moving Auckland anyway into a better slot and [The Bend] needed to be later in the year [further away from the Adelaide 500].
“From what we have seen now with Sandown in terms of the new date [for 2019] and the response that we have got from ticketing and the response we have got from the TV networks about that time, we believe late November is better for Sandown.
“[The Bend] is a great facility for doing an endurance round, so it’s a combination of weather and scheduling the other events, and not wanting to move Sandown back out of November into September.”
Sandown’s retro theme is meanwhile under review, having run as a history-flavoured round – most visibly with teams adopting past liveries – since 2015.
Playing on the heritage of the Sandown enduro, which traces its roots back to the early 1960s, the theme will continue for this year’s event.
“We’re still working through the look and feel of the event beyond the format,” said Seamer of Sandown’s 2020 fixture.
“What we do want to do and what we will continue to do is make sure that as best possible, each event has its own unique identity and has its feel.
“The retro round has got to work, so we feel like we need to put a bit more effort into it if we are going to keep it.”
