There's your help.

 

4.75 max back spacing on most UCAs out there.

 

Wait, how does a 12" wide tire fit on an 8" wide rim?
Wouldn't the bead be constantly under an abnormal angle???

 

All I'm saying is this statement is ludicrous. Because I'm pretty sure I had my original wheels on after I had my "aftermarket lift" on and nothing exploded. Also why not just call it a lift, cause they're all aftermarket.

 

Whats hitting the UCA? Pics would be a better help than anything you've tried to explain thus far....

 

Get some spacers and call her done. I’m confused why you are now having this issue and not without the lift. Perhaps maybe you were all along during down travel and now with the lift on and the arms forced down to accomplish the lift and thus the issue is now apparent.

Consider spacers like others have suggested. If not a big fan of the push out from them Bora makes 3/4" spacers which gives minimal. Just confirm this will be enough to clear
