I am running a stock LS1, T56. I have the body stitch welded from wheel well to wheel well, with an angle brace welded in going from near the front strut top down to in front of the bottom of the door inside the fender. In the pictures above, you can get an idea of the amount of lean the car is getting in the turns. This was with used clicks, -1.4 camber in front, -.9 in the rear, I think 4 degrees caster. I was staying behind an MR2 that stayed really flat in the curves. We were running about the same lap times, but he would pull away from me in the turns, and I would catch him on the straights. I had bought a rear bar, but ended up sending it back before I even opened it after reading the suspension FAQs. Seems like a lot of people there use 1", but their cars are probably much lighter than mine.
