With stock wheels the extensions do look silly, even with 35's although I'm not sure if they are 11.50s or 12.50s.
I put on the XR flare extensions, aka "spats" in MOPAReze", on my Wrangler but but the offset was -12 vs. the stock 44.5 mm offset so it worked out just fine.
Now that I have the JT I need to add those spats to it. My ProComp Bandido wheels have a -6MM offset vs. the same OEM offset as the Wrangler.
So I've ordered the "spats", two left front and two right front, and will be ready to install them after they arrive.
