I’m not an amplifier expert, but if takes 30-40 amps, then you’re killing yourself with a body ground. Be careful of ground offset. Treat the block as the main(priority) ground, then ground the body and the frame to the block. The fans and amp I’d recommend directly to the battery.

Have you considered having the fans on two different switches? One at 180 and one at 195? Also, ground the battery to the block, not the alternator. If any of you current grounds or positive wires off the battery, starter or alternator are stiff (like wedding prick), then replace them.
Fans and amp are directly to battery, fans with a relay and 30 amp fuse. Amp has a mega fuse. The way I have the 4th gen Camaro ls1 (according to the guy I bought em from) fans wired is full beans by grounding the wires that would otherwise go to a fan switch. Unground them, fans slow down. Haven't had luck finding a fan switch. The battery negative is grounded to the block via an alternator bracket bolt that threads into the head.

I'd be surprised if the front didn't settle more. I'm curious to hear if the ride went to sh*t with those mounts too.
Those front springs have been in the car for 12 years. The rears are new and I'm hoping that drops a hair.

The settling bit isn't about the springs "breaking in", the only springs I've ever cut were used and both settled a bit after a drive.

I positioned the bottoms in the stops on the LCA so I'll be surprised if it gets lower.

You can buy a switch that threads into the head, intake or anywhere that has a coolant port. Use a large pin relay - pin 30 to the battery with a fuse inline, pin 87 to the fan 12v+, pin 85 to a 12v+ source that is hot only with the key on and running (not hot when cranking), and pin 86 to one of the switch wires. The other wire in the switch put to any ground source.

You buy the switches anywhere - Amazon, Summit, EBay, etc.

This is how my fans are wired. Kicks on and off at a preset temp using a temperature switch in the intake and kicks on when the A/C turns on using another relay.

I took some measurements with how this car is sitting right now flat on the garage floor.

The body corners behind the front tires to the body corners right infront of the rear tires:

Rear Higher 1"

Center of the front wheel well to center of the rear wheel well:

Rear up 3"

Wheel gap looks what it does because the rear wheel well is 2" taller in the rear. Body is 1" taller in the back on the bottom so when the new rear springs sag that will close that gap. Have to see what the wheel well does. It would be lower if I didn't have the 9" Rear, the axle tubes are bigger.

I bought a pair of the Holley RetroBrights and installed them in my Regal Today, I did have to trim the 4 tabs to fit with my modified headlight buckets from the previous LED headlights but other than that a direct fit. These have a very nice cutoff which was my biggest issue with the cheaper ones but still a lot of money for a pair of headlights.

I have had the 2" drop UMI rear springs in the back of my Monte for over 10 years and they haven't changed ride height from the day I installed them.
My tires are 28" rear and 27" front, my front springs were stock SBC replacement but there is a BBC up front and also a Moser 9" in the back.
