This is kind of a spin-off of the hub centric vs. lug centric & ProComp 7089 threads( http://thenewx.org/phpbb2/viewtopic.php?t=6441&start=75 and http://thenewx.org/phpbb2/viewtopic.php?t=6638 )...though despite the pending issues w/ those wheels, are you guys having any issues (besides the wheel well rubbing mod) when you upgraded? I had some major drive vibrations first couple days after install, got about %70-75 better after alignment yesterday. MCAmpana suggested taking them back for re-balancing, did you all have to get them balanced more than once? What wheels are you running w/ them? THANKS!
