OverRev found "front tires (235/40/R18 RE71R on 18x8 ET40) rubbing a lot." He is on H&Rs so 1" front drop.
rwalker found "Before LCAs I had -2.5deg camber to fit my 255/35r18 fronts on 18x9et36. F8x LCAs introduced another 0.9deg, about 1" of forward movement, leading to rubbing in the front upper part of the fenders, requiring fender rolling."
Icy J found "had to replace 10mm spacer with 5mm and raise height twice to minimise rubbing." ..... notice this man is running a poke i have never really seen before up front and slammed on 225 tires.
Bee Pee found "rough measurement of the M4 arms being approx 1/2" longer"
Also refer to my post below, i put together yesterday, if you want to do this on a budget and right....
