I just remebered I ran into an annoying problem with Flex a Forms a few years back. They said its not a problem. I disagree. I suspect the fiberglass springs are made up as one long arc, and with designated design rating. After curing, the arc is sliced like a loaf of bread into spring widths as needed. Additionally, the "arc" is thicker towards the center, and thins towards the edges, depending on how the sliced arc is shortened to needed spring length, this thicken section can be placed in needed location where the axle housing is bolted, ie the difference between SS springs (20"?) front segment and reg (22"?) front segment.

Anyhowe, I will post later a pic of the set I am unhappy with, and you decide. They would not replace them, and I installed them on a beater Charger 318 B body.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
