I've got a XXX-S G+ and I don't understand how the rear toe works. I have the stock hubs and arms in now which I think is 2 deg. I want to get 1.5 deg. Do I just get the .5 deg rear hubs or does this give me 2.5 deg of toe-in? Or do I run the .5 deg hubs, but with the left one on the right and the right one on the left?
