I've got the ones for a teg on my sol, and I leave em on 4 all the time all the way around. (for the tegs they only go to 4 front and back)
It ends up plowing at times, but for the most part, it just stays steady as hell. I'm running 450lb/in front, 350 rear. With stock springs, I'd probably go pretty low on the front. MAybe 2... And somewhere near the middle on the rear. 5-6 in your case.
