I ran the 1LE sway bars with the stock 245/275 staggered set up. It worked pretty well but I had 1.2-1.4 negative front camber which kept the car very neutral at the track and autocross. I now have the 1LE bars with 275's on stock nine inch wheels all the way around and 1.0 negative front camber; it has frustrating understeer and excessive outer tire wear at the track and autocross.
The 1LE bars with 1.4 negative front camber/1.0 rear camber and 245/275 tires is a good set up based upon my experience.
