The next round of the Shannons Nationals will be free for all spectators at Winton Motor Raceway.
As part of the fifth round of the season, the Winton event will be headlined by some of the best series and championships in Australian motor sport.
Approaching their final round at Winton will be the CAMS Australian GT Trophy Series, with an epic battle lined-up for the series crown.
A pair of Audi R8 LMS Ultras currently lead the way in the standings, with Nick Kelly 30 points clear of Rio Nugara.
Just five points separate two young guns in the Porsche Michelin GT3 Cup Challenge, with Cooper Murray leading the way ahead of Simon Fallon in the outright standings.
The series has had a bolstered field so-far in 2018, producing both excellent sprint and endurance racing.
Fans will be seeing double as the CAMS PAYCE Australian Formula 4 Championship hosts two rounds at Winton.
Set to play a big part on the championship standings, Jayden Ojeda currently leads the points table ahead of Cameron Shields and Ryan Suhle.
The ever-popular Australian Production Car Series will return to Winton for twin two-hour races over Saturday and Sunday’s racing.
The Porsche 944 Challenge will make a comeback to the Nationals, with the older-make Porsches to hold a non-points round at the event.
The invitational 944 event will run in honour of the series’ creator, with the Dennis O’Keefe Cup to host an exciting format that includes a reverse-grid race.
