I tried for over a week to get someone from USARim to respond to my emails to no avail... I tend to avoid places where I get poor before-the-sale service. Ended up hitting up Vassilli at
Power Wheels Pro :: WHEELS for your PREMIER car. I'm going to try the wheels without the spacers first, but it's still going to be a few weeks before they have stock.
To bad they do not have any 19x10.
