Welcome to AF !
You saying you heated the Eibach springs ??
, that was a waste if you did. I hav seen 2" drop- Eibach springs before, cant remember where at the moment...
you should hav just heated your old factory springs, but over time either will break down because the temper was heated out.
And ya its a big differance between the 1.25 and 2" springs.
You get to low and you'll need the camber kit with new shimes so the alignment will be dead on, other wise you might go through some tires.
I havnt done any GAs but on other cars/trucks.
Clearance issues may also arrise from the vehicle being to low and the tires will rub the inner fender well.
Good Luck
