Here’s a 360 Sprint setup for Weedsport Speedway 2022 Season 3 as prepared by Weston Newell.
Lower the packer to loosen, raise the packer to tighten. Lower the stagger to tighten, raise the stagger to loosen. Wheel spacing is also a good option. Adjusting these setups will not give you any more speed. Adjust for comfort only.
You can easily make a good iRacing Sprint Car qualifying setup from this race setup.
