Definite scrub line issues unless running big diameter wheels. A 1.5" block on 15's is the safe limit. They're close, but as long as you don't sling the rubber off the rim & the u-bolts don't extend beyond nuts, you'll be ok.

That being said, I've seen more than one guy use 3" blocks w/o problems. It just seems to be an un-worthy risk.

Boris, what are you getting for the blocks?
