Took it out a cut another sidewall a couple of weeks ago. On a positive note, the e-locker worked flawlessly.
While rotating the tires around so the one with a sidewall patch would be on the rear, I ran into the same brake caliper clearance issues I had when I first bought these rims. So I let it sit while I waited on some 1" wheel spacers for the front and 1.5" for the rear.
It's got some stance now, but the tires were rubbing the fenders a bit when I turned. I fixed that, but they still touch the firewall a bit when turned and flexed. I'm gonna try the cut and hammer method to gain the clearance I need. I don't want to tub it yet, but if I do I'm going to tub it big enough for the inevitable tire size upgrade...
