That's a hefty question that needs lots of research or multiple congruent first hand experiences to make a determination.
Example: Chinese Craftsman wrenches. Many people say they're the same and work great. How do we define that they work great? Usually, 'it removed the fastener' is all people are looking for a a qualifier.
Hell, by the same standard, an oxygen acetylene torch is a great wrench, and people don't look at factors like: Did the wrench damage the nut, did the wrench remove x number of fasteners before it wore appreciably, did the wrench fit in the same locations as its American predecessor, did the wrench apply maximum torque before failing, did the wrench resist corrosion accordingly, and so on and so forth.
I can tell you that the wall thickness on a Chinese Craftsman wrench is much thicker than its American forefather. Why? The material is lower quality so they needed more of it. I can also tell you that the Chinese wrench will bend far more easily because the material is either softer/ weaker or because it wasn't heat treated properly and this leads to greater wear on the wrench when used on harder fasteners. The wrench isn't sized right, and therefore grabs the corners of the fastener instead of the flanks, so on and blahblahblah.
The SS springs can't simply be measured to be a different thickness and that's all she wrote. The material, heat treat, life cycle, etc all factor into it.
I don't know the answer, but take the above into account in your answer.
Also, how can I tell what's under my car? I have two of the same spring per the Mopar Action green brick build. I need to get them lowered but haven't researched the right way to do that.
