Port Lincoln Bendigo Bank has increased its financial support for the Teakle Auto Sprint, which is coming together for the 2020 event.
The bank has pledged $25,000, an increase of $7000 from 2018, which will go towards providing big screens for spectators.
Auto Sprint chairperson Tony Rodda said everyone was excited about the bank's increased support which would go towards more screens, including around the TAFE area.
"It allows us to give the spectators what they need with the big screens...it brings all the action to them," he said.
Port Lincoln Bendigo Bank business manager Phil Channon said the underlying reason for the increased contribution was because of the amount of people the event brought to the city, which in turn promoted the city to those who had not visited before.
"I'm a firm believer...we actually double the population of Port Lincoln for that weekend and for businesses in town, whether it's supplying food, accommodation, drinks etc it gives these businesses an opportunity to make extra money," he said.
The 2020 event is taking shape with a full line up of 75 entries confirmed, including 30 new competitors.
Mr Rodda said the three top place getters from 2018; Dan Day, Nick Streckeisen and Mark Rundle would return as would highest finishing female entrant Amanda Sparks.
"Amanda Sparks was sixth last time and is coming back with a new Porsche GT2 RS, having her back is super exciting because she's really fast," he said.
These drivers will join seven-time Bathurst 1000 winner and Australian Motorsport Hall of Fame inductee Jim Richards, who will enter with his Shannon's Porsche GT3 RS.
People will also get to get up close with a Larousse team Formula One car, which will include seeing it get prepared for the track and take to the track for demonstration laps.
The Teakle Auto Sprint will take place on April 11 and 12.
