Yes, obviously unstrung weight has a bit more of an impact but it’s no where close to your numbers
My point is simply that the performance return for the money spent is not worth it on the street https://www.cjponyparts.com/resources/sprung-vs-unsprung-weight
I’d think the performance increase in acceleration, braking, handling and improved ride quality for basically the same money as a cat back, is money better spent.
