It will hit the calipers FOR SURE. I looked into this when I was tire shopping. Found a set of (4) chrome 16" OEM steelies (from a gmt800) with Cooper Discoverers for $200! We tried, but it was no good.
I Didn't feel like compromising the integrity of my brake calipers...... If you changed all of the calipers and rotors maybe it would work.....
I noticed NBS, and NNBS were nulled and replaced by the corresponding Model #'s. Can one of the other terms be removed as well; OBS and OOBS wasn't there a GMT400 that can replace one of those?
-Thanks Ryan!
