Installed the springs in December. There was a light knock here or there seemingly right behind/to the left of me. I mainly hear it in parking garages and it's not while driving over bumps, and it's not consistent with my turning. Now it's gotten a lot more frequent. I took it back to the shop and they banged on suspension areas with a mallet and couldn't find anything loose or noisy. Another shop thought it could mean bushings might need to be lubed. Anyone have any ideas what it might be? Again, it's only noticeable when I'm coasting in 2nd gear in a parking garage. I thought it could be my side skirt, which I saw came loose at one point. I pushed it back in, but it doesn't seem as sturdy as the passenger side.
Edit: SPC camber kits were installed as well.

How many miles on the suspension? Does it occur when applying throttle, making turns, etc...?
I heard it probably the next week, so not many. Doesn't occur with throttle. It does happen more often during turns, but I'll hear it while going straight/down a ramp as well. I can't really reproduce it unfortunately.

I just asked the shop because that's what someone else suggested and they said they were tightened while loaded.

I brought my car to the dealer and they inspected the sway bar end links, upper control arm, shock absorber, and subframe bushing and didn't find anything. They also tightened down loose panels and the spare tire. It seems to show upmore when there's a weight shift after taking my foot off the gas. They're blaming it on the aftermarket stuff and suggest returning everything to stock to further diagnose, which isn't going to happen. Is there a chance the springs could be shifting, creating a popping sound?
Strangely, the noise doesn't come when I go over bumps. Sometimes I think I should've just left my car stock. Running into so many issues with shops working on my car.

Do you know how they inspected the sway bar end links? Those are a common issue after changing the suspension as the stock links wear out fast. A good test would be to disconnect the end links and see if there's a lot of play. I've also heard of driving a bit when disconnected, either completely removed or zip tied to prevent it from banging around, to see if the noise goes away. Obviously don't drive around like this for a long period of time.
Has the handling been compromised at all? I had a similar clunking sound when I first did my coilovers and the lower control arm bushings let go. They looked fine from what I could see visually but once I popped them off they were mangled:

They said they used a chassis ear.

Not that I can tell. I figured it may be some sort of bushing on its way out, but people just did quick checks. The next step would be to take everything apart and inspect each piece, which I might do if it continues to do worse... but I'd pay someone since I'm not equipped and don't have a garage. Did you replace the bushings with solid ones?
Mine did not appear mangled when looking at them either. It wasn't until I popped them off when I saw how bad they were. I put OEM ones on but OG has a set that I may try:
