Lowering springs/suspension

I read A LOT of threads like this before I bought mine. Mostly all of them kept asking the me the same questions:

Whats more important, Cosmetic (lower) or performance (handling) springs?
How much (if at all) do you want it to lower?
Daily driven or weekend warrior?

I found great reference to compare springs here:
How to Lower your Mustang Article - StangSuspension.com
Mustang Spring Rates and Specs Article - StangSuspension.com

Ive also heard TheDukeOfEarl is the proclaimed guru on here when it comes to hard handling our land beasts.

It all depends on what you are looking for and what the car needs to do.

on my old Cobra, I ran FRPP B Springs, MM LCA's and it lowered my car nicely. It just caused the headers to scrape.
