I'm about to start my lowering spring install. Anyone have any in site or does and don't they care to share?

Two nuts/bolts on the front knuckles. Remove the nuts and knock out the bolts (they're splined into the knucle). Remove the 3nuts holding it to the strut tower underhood. Compress the springs, remove the top spring retainer nut, swap the springs. May need a set of visegrips to hold the very top of the strut shaft to keep it from spinning. (ONLY at the very top of the shaft, you do not want to scare the area that travels into the strut/shock body) The rears just use a jack to compress the susp. Arm and disconnect the lower control arm from the knuckle. Lower the arm, flex it down if nessesary, remove the spring. The rears took me 1hr. The fronts take abt an hour and a half - total if using a hoist.

Necessary to have aftermarket camber eccentric bolts when doing the h&r springs?

Yes! Some people on here say no but I had my car measured twice and it was well out of the threshold for alignment specs! Search this forum for H&R, Springs, etc and you'll see all the posts and my post especially about the rear camber bolts you need.

Some say yes, others say no. I took my '13 SHO with the performance package to a reputable performance shop (they work on a bunch of exotics also) and they said my car already had enough adjustment with the OEM bolts to get the car back within OEM specs (without any trouble at all). I am the second owner (purchased at 43k miles) but I doubt the original owner removed his lowering springs and left the adjustable camber bolts before trading it in. I now have a pair of (New In Box) camber bolts I'm looking to get rid of for $20+shipping...
