i have been doing some work on my stang and have come to a crossroad. i dont know what size offset rim to order... the car has had new rear rails put in inline with the front frame rails and then thru the floor subframes. so now i have basically a clean slate as far as having enough room for the rims on the inside. but my questions is if i have a stock width 52" flange to flange 9 inch housing will the late model 17x10" rims fit on the inside of the quarter panels? the wheel dimensions are 17x10" with 20mm offset or i might run a 17x10.5 with 27mm offset. sorry for the dumb question i am just not very good at calculating offset and backspacing stuff
