I run a 16:1 Flaming River manual steering box, 275/35/18's up front, and +6.5° of caster. I use the car almost daily, I do a 120+ mile round trip commute weekly which includes mountain roads, highway, and freeway driving.
@Kent mosby - looks like you've only got about +3° of caster, so, if anything I would add some additional caster if possible if you went to an EPAS set up. With 215's up front you might not find it necessary, the wider the front tires get the more likely they are to wander and positive caster improves the self centering effect of the alignment. Which is why I run +6.5° with my 275's, makes for a much more stable car at speed.
I don't have any issues with mine, it is definitely not something you want to have to do a lot of "dry steering" with- ie, turning the wheel while the car isn't rolling. But like I said, I literally get groceries in my Duster and parking lots aren't a problem as long as you have a plan for what you're doing. If I was parallel parking everyday I might do something different. And we'll see if it's too much on slow speed autoX courses, it's fine above say 20 mph. Below that it can get a bit heavy, but not unmanageable
