Following the SKOSH chart - your experiences?

It is very stable at high speed. tracks very straight on the dragstrip. 11.46 at 118+ no drift or squirrelly motion. Around the street if I did not have the shoulder injury, I would be fine. I will have to have it aligned after and will ask if they can get more caster

If the high speed stability is fine how it is now you don't really need more positive caster. With 215's up front it shouldn't really be necessary. It would add some more camber gain which would help handling, but it doesn't sound like that's a big concern. And of course it would add more steering effort, although that should be handled by the power assist.

The caster requirements go up really fast once you get past a certain tire width up front, so the 275's I run definitely need a lot more than the 215's you have.
