If you're in the So Cal area, I called a few places around to see who can install my springs. Eibach said they can do it themselves for $400 with alignment, but they're short on staff due to stay at home orders, so when that's lifted they can then start doing installs again at their facility.
I then found a couple of recommendations by a people on here who have gone to other places. I called Auto Talent and their prices have gone up in the past year (over $125 from what others posted). I then also saw Mod Bargains and gave them a call, and they charge $280 to install the springs, or $400 with alignment. The good thing is they're even closer to me than Eibach, and they can do the work now.
Once my springs get delivered (later this week), I'll be taking my car in next week to get my springs installed since my car is looking like a 4x4 right now after putting on the 20" perf wheels.
