Their phone support was good but the product just failed hard.

FYI Broken strut tower stud, broke before vendor spec of 18 lb-ft. Other side was halfway gone in same location. The horseshoe piece flexes too much during install and the bolt separates from the head. IMO the allen-head recess weakens the bolt at the base.

--correction, the "weld" didn't break. The stud twisted off the welded head. ---

Fix involves dropping the suspension, fix/replace part, realign front end.

Did you use power-tools? Did you do the alignment yourself?

I bought a set of GC coil-overs used. Prior to the installation I knew there's potential for trouble, it had appeared to me that while the prior coil-over installation was correct (in fact I knew the mechanic who installed it), the subsequent alignment, since the shop that did the original install did not have alignment rack, the guys doing the alignment had over-torqued the nut(s). So of course when I went to install the used GC kit on my car, the weld on the stud broke off. I sort of had an inkling that this was going to happen, because when I received the used kit it had appeared that one of the studs had some damaged threads.

When I get the new plates in and installed, I'm going to have to leave a note with the alignment shop to make sure they PROPERLY TORQUE the strut nuts and do not use power/air tools. Sometimes inexperienced shops will use a power tool or an air tool and even an air ratchet can deliver enough torque to do some serious damage.

Otherwise the GC kit was by a very far and wide margin one of the easiest suspension installs I've done. Took me about 4 leisurely hours spread over 5 days at work, including about half an hour modifying the trunk trim with a Dremel to allow access to the rear shock adjustment.
