[QUOTE=Sampsue. Maybe a stupid question, but how do you balance an adapter? Now the adapters are hub centric bolted to the hub with 14 x 1.5 60 degree beveled open ended lugnuts and the rims are hubcentric on the adapters with very large open ended washered nuts. The couple of times I've dismounted my rims and remounted them, the large washered nuts don't seem to go back to the same spot, but the rims fit very tightly over the hubcentric part of the adapter so I can only assume they are mounting hubcentric. .
Thanks for all the help guys. Jonny[/QUOTE]
Jon,
Lay the truck up for a couple of days and find a reputable machine shop that you can trust, have them check the trueness of the bolt patern that the wheel bolts to, make sure that the bolt pattern where the adaptors bolt to the truck are true, and then have them balance the adaptors(as long as everything else checks out)..Or box the whole mess back up and call Brentz wheels and ask them about building you a set of predrilled super singles.
These are just personal opinions based on previous experiences. and everyone has opinions.
