Your opinion on the best suspension with Porsche Wheels?

I know this is entirely preference, but I know going to tires that are 7.5-9 inches wide, it kinda limits your choices.

I don't care about a harsh ride, I care about how it performs. What's the best spring and shock combo for a 71 super? Keep in mind, I'm having CB dropped spindles(possibly, they aren't bought yet), so my ride will already be lowered in the front by 2.5-3 inches.

I'm planning on doing this all at the same time, switching to porsche rims, 944t brakes, and lowering it.
