Scampchamp...not sure what your application might be, street or strip but the ss springs wouldn't be my choice for a driver. I'd go with the heavy duties...you can pick them up pretty reasonably from Mancini.
I've been running the 002 & 003's for years. I tried the mancini heavy duties on one car when they first came out, but liked the old Super Stock springs better.
I prefer using the 002 & 003 for mine. They ride nice and handle well on the street also. I like the "attitude" that it gives with the rear end slightly higher than the front....
