My only point is that there are things to be considered and at 3" I don't feel it's the go to fix when the caster is still out.
I'm not against using the high steer setup, but it has to fall in place with the rest of the build and the rest of the parts that are already in place. At 3" and on 35's he's border line. 3" is the recommended/minimum point, not the required point as many have proven.
I'll also be right around the 3" mark and am considering the high steer setup. I also don't plan on running more than 1"-1.5" of bump stop at the very most though either and will have to notch the frame to clear the steering and trackbar. There are still some things to consider before I decide though.
