the biggest pita part is the rubber orings that actually seal the wheels. some guys on pirate 4x4 were using crisco to get them to seal.... but that was about 7yrs ago when i used to have a jeep and keep up with that forum. i have been out of the hard core 4x seen for a while. the rims were cheap then and people were using them for bead locks. there used to be a place that would cut the middles and offered offsets and custom centers for them.
