camber, rear, john, adjust, drop, size, inch, spyder, springs, brand, lower, lowering, tires

I would like to lower my Spyder with springs. What brand should I go with.? Will tires rub anywhere....all four are the same size as rear. How bad will the camber be with a 1.5 inch drop. How, with what, do I need to adjust. thanks john
