I just recently came across the GNX look a like rims off of a 88 Trans AM GTA. I want to put them on my 87 GN but need a little help. The tires on the GTA rims are 245 50 16 and of course the stock tires on the GN are 215 65 15. The GTA set is front and rear. Will this work? What is the easiest way to do it? What spacing if any is required on the front or rear? What size tire can I use to cover the GTA rims but are small enough to fit under the GN? I know the 245 50 16 are trouble to get under the rear of the GN? Any help provided is appreciated. Thanks.
