my lift in the front of my VX measures 39.5"'s from ground at center of tires to highest point of cladding arc. I am running 305/70/17's though which is about the equivalent between 33" and 34" by 12.5"'s. You did put taller springs in the rear of your VX didn't you??? because I have the Calmini springs in the rearend of my VX and my wheels DO NOT EVEN COME CLOSE TO RUBBING in the rear end of my VX.

Now the front end of my VX with rubbing issues, now that's another matter. I have loosened the cladding and cut and grinded ALOT of metal away and relocated all inner and lower most wheel well panels back farther and they still rub if you turn toward the drivers side and hit a bump like a curb or gutter....even if they do not rub sometimes, they are STILL VERY CLOSE TO RUBBING.
