Eibach springs do sit lower in the rear than the front. They didn't go bad - that's completely normal for them.
Regardless, thank you for the information about H&R springs. Glad you find them to be workable for your application.

You can adjust it yourself, as long as you're sure that you're always running a sufficient octane of fuel in your tank to match whatever boost setting you put into the boost controller.

That depends entirely upon the exact fuel that you're running in the tank. With USA-spec 93 octane (calculated using (R+M)/2), you can safely run 16psi with the oem ecu's ignition timing curve. Anything more than that and your 2jz-gte's compression numbers will deteriorate over time. Anyone who tells you differently should offer to replace the engine if you follow their advice and the engine gets damaged.

Less or more? When I got the car the settings were pretty much set on the middle of both the low and high boost settings. I run premium fuel 91 or better all the time.
...

With 91 octane fuel, it's probably 15psi or less. I'd recommend a 1.0 bar limit (~14.5psi)

Have you considered methanol injection?
