The shop looked at all of the new parts, timed the bushings, and checked the bolts, so it's unlikely something is loose. I'm thinking it's just a combo of stiffer parts on an older car. Further investigation is necessary... to be continued.
Suspension is getting really annoying with the noises. The noises make me nervous to even attempt to see what the car is capable of. Last thing I need is to have a bolt fall out while cornering.

I'm fairly certain it's not the exhaust. It has plenty of clearance and the noises aren't coming from where it would normally hit (went through that back when I did the exhaust install). From how and when the noises emerge, it makes me think it's the springs. I am seriously tempted to take the springs out and try re-installing them.
