Yes please! Have you considered Buxton?Carsten suggested a sort of demolition race with the Ducks.
How about this one: https://www.racedepartment.com/down...iana_sportsdome-speedway_figure-8-oval.28318/

Better graphics and tighter turns/ banking = more mayhem!
I think both Clarksville and Buxton have limited pitboxes (12 & 13), not sure if this limits grid slots too??
Full on demolition would require a higher damage percentage but then you don't want to be taken out of the racein the first lap so maybe 10% would work. Also, I would suggest shorter races, maybe 3x 20 mins or 4 x 15 mins.
