I've read up as much as I can find about the 6 lug conversions for my hubs on a 92 Loyale. I have never found anything on the minute difference in the 6 bolt pattern to the 4 bolt and any affect it has. The subaru is 4x140 and from my understanding the 6 bolt is 6 x 139.7. I have rims from a Nissan Pathfinder but am unsure of the year. I have knocked out the 2 opposing lugs and when I bolt the remaining 2 into the rim I can notice that it is not seated perfectly, which I would assume would lead to an unbalanced tire. My car will be doing plenty of highway miles, does this warrant any concerns? Also, the centre bore of the rim is larger than the "axel seats" on the hub. I have never heard of anyone using hub centric spacers to fill this void. This seems extremely important to me as that interface is supposed to bear the weight. Does everyone use these spacers and I just missed it? All the help is appreciated. I am not an experienced car guy and am learning as I go so please be nice!
