Just as a note...
I first installed my ProComp lift with the strut spacers backwards. I thought I had the directions right, but the camber angle of the tires was more like / \ . So, I spun the mounts, so that the tabs for the shacks was to the rear. The camber was closer to | | . The problem? It takes away some of your caster angle... and on-center feel and return-to-center.
I just put 30's on it. With the spacers backwards, the tires rubbed LOUDLY on the front bumper when the wheels were tunred close to full stop ... but only while backing up. Since I spun the mounts back like they are "supposed" to be, I get light rubbing on both the front bumper and the plastic bachind the front tires while braking and turning. This is pronounced when hitting those side streets with the drainage dips.
Just my opinion... but I like Whitfield's front mount. The ProComp control arm drops sit pretty low for giving "lift". I whacked mine today on something in a mud hole, and this is what I got:

I guess I shoulda put the skid plate on... but I left it leaning against the wall in the shop... :-/
