hoss 18x9 backspacing

Ok so ordering wheels soon... Found a suggest wheel. Only available offset listed is zero... 18 x9 0 offset... will there be issues?

 

Will be close to hitting the uca, but some of the guys running rockstars (5" bs) claim no rubbing on the uca with the 12.5s.

It's still going to require a lot of trimming.

 

Stupid newbie question... what does uca stand for?

 

Upper control arm?

 

I had 18x9 +0 wheels and used to run 285/60/18's with zero rubbing at stock height. You should be able to clear the UCA's with 285/65/18's on 18x9 +0's, and with 3" of lift you shouldn't have too much rubbing. You'll probably still have some trimming to do, but it shouldn't require a significant amount.

Yes, UCA is Upper Control Arm.
