It seems gmt400 trucks run less spacing in the back to keep it flush against the fender.im almost pulling the gun on sum 17x8 torque thrust chrome.for the front and back i know 17x8 with 5 inch backspace works great but if i wanted a lil more lip for the back would 17x8 with 4.5 inch backspace still tuck on 4/6 drop? Just to clarify 17x8 with 5 inch in the front and 17x8 with 4.5 inch in the back.tire im going to run is 255/50r17
