Just an extra install tip, if you have trouble creating the needed 30mm space between the strut housing base and knuckle to install the RCA, try disconnecting the endlinks for swabar, will give more leeway. Better yet, disconnect both front sway bar end links. Also, of the two longer bolts to remount the strut housing, the rearmost bolt may hit the edge of the knuckle flange whereas the stock bolt, being shorter, is more easily inserted. May need to grind a bit of metal off the side of the knuckle flange. Not a big deal, and maybe not effects others. I replaced my susp arms and perhaps their shape is a bit diff. Anyway, a little dremel work is ok.
