The fenders don't add much. They get rid of the flange that the flares mount to but that's like 3/4". 2" bumps were enough to keep 32s out of the stock fenders before I cut them off the TJ, and though I didn't cycle before tearing the LJ apart, I havent found any signs of contact between the 33s and the stock fenders with the 2" of extension it had.
I'll know for sure later in the week, my Currie bumps are supposed to be delivered tomorrow. I was fine with what I had except for this happening when I put on the Currie 4" springs.

I'm admittedly at a loss how you're getting tire contact with 3" of extension and what looks like 2" of air still in between with 33" tires. Where exactly are the tires making contact? And what specifically are you tire and wheel dimensions?
