The SS springs are special with two different static arches. Yours should be fine.

The torsion bars are aftermarket and may already be a bit low because of the low profile tires. I am looking to raise the front up to almost level the rocker panels. The lower bumpers are very close to the the pads.
Set it per the shop manual, not body hieght. If you want to lower it from there, fine, but use the factory measurement method. Body panels aren't accurate and the wheel and tire diameters change the number, etc.
If you run it with lower ride height, trim the contact bumper. keep the shape as much as possible.

This leads me to believe that I should get the +-2.5 for both sides and just match up the lowest number I get from the both sides during adjustment.
Struts are stock with new rubber bushings and even the roll pins in the low mileage struts.

I see. Those seem to be a claim on the amount of movement available for adjustment. The implication from the parts description is that the car has 0 caster in the middle of the slots - which isn't neccessarily true at all. So those misleading descriptions.
