those wheels will be a bit of a tight fit on an ae86, for that width of tyre the offset will mean it will sit very close to the strut. im assuming the ofset is +20something if it is off a silvia. but yeah correct me if im wrong.
umm btw do you have an ae86.. ae82 or both>?
because ae82 are 4x100pcd so the rims will not fit.. at all
unless you weld them to the hub, which by the way was a joke. please dont try it.
