Wow, I'm surprised you had trouble with clearance on your 4a - I thought with the suspension changes the 4a was in better shape than the 4.
I dry fit my 5.5" rims to the front, without tires, and things were tight but everything appeared to clear.
I will also have to check a little carefully on the variations of the KN wheel from the previous note. My two wheels have a small lip on the edge I think so I may not match perfectly. Didn't really buy them for show anyway I just wanted something wider for normal driving to get away from 165-15's.
Thanks all,
Randy.
