Well I finally dug into it to get some minor stupid issues sorted out. Loving the new H&R suspension but she was still too low with the perches maxed out in the rear. Ended up selling my FKs and the guy that bought them wanted to go hella low so I swapped rear perches with him. FINALLY have it sitting at a driveable ride height. No more rubbing or bottoming out!!!!
The other issue was with the CTS Turbo back. Fitment is crap with CTS and it was rubbing on the rear subframe/control arms and was driving my wife nuts. Got it oriented in a way it doesn't rub anymore but the tips are no longer centered in the hole.
For the first time since I bought this car, it's running right, has no odd noises, trans is good, shes just golden right now. Once we get the wife's new car I'll be drowning this for a week or two and pulling the motor for a whole reseal (bitch leaks oil from everywhere). Once that's done, a side from a few minor things here and there, the cars done.
