This setup is made for South Boston Speedway 2017 Season 4 night racing. It was made by increasing the stagger and balancing the tire wear on the iRacing default setup for this track. Tire pressure and springs were unchanged. I believe the shocks are still default. As I recall, the only things that were changed are the tire staggers, cross weight, and maybe the track bars.
I have three setups for this season. Number 2 is similar to this one with a few more tweaks. It has a little bit more stagger and lower tire pressures. Number 1 is what I would call my setup for this track. The stagger is where it should be. The car turns better but is not loose. It might be just a skosh slower than the other two in the early laps, but it really pays off in longer runs as it stays very stable.
