Check this out! This guy is running 18x11 +25 wheels. Compared to a 18x10 +14, his only will stick out 1.7mm more. He has to run -9.5 rear camber to tuck a 235 on an 11. So, If you want that 18x10 +14 to fit, and you buy some LCA, it's possible. (you probably will need a few other suspension parts too)

Racer X has some extreme Rear Upper control arms to get -9 or more negative camber.

Also, this is a great offset tool.
