Here’s an iRacing SK Modified setup for Five Flags Speedway 2019 Season 4. This setup was prepared by Old School Racing Motorsports.
This track feels like it was made for this car. It’s a lot of fun to drive the SK here. I would advise staying with this gear although it may feel too tall for you. The key is to keep up your momentum in the turns. Don’t use any brakes at all, just lift briefly around mid-entry. Keep the left side tires on or below the blend line. You will profit if you can stay up on the wheel and keep your momentum for the entire race.
