I have 3" Schroth shoulder belts in my 6 point harness used with a Kirkey seat. The cut outs in the seats for the shoulder belts are very close together (probably a 1" gap). This makes it pretty uncomfortable at the track when I'm strapped in. The closeness of the shoulder belts when tightened down dig into my neck. Is my best bet going to 2" shoulder straps for now? I'm not currently using a HANS (at some point I will). 2" shoulder straps can be used without a HANS, correct?
