hey guys i am in the process of getting rims, i want a set of 18x7.5 or 18x8 Momo Arrows. i know they are discontinued, but would shops still carry them or be able to get them? that's question number one. question number 2 is, for an 18 inch application and 7.5/8 inch width, what is the lowest offset i can go without rubbing on stock suspension, springs and height. question number 3, what size tires should i get? thanks you guyts have been the greatest help.
