That's another thing when guys are simply quoting things with no details, or none that relate. A guy swaps in new replacement 'stock height' springs in his Camaro (sure, why not) then complains how high it sits. He jumps online, says his 'stock height' springs are too tall. Wants to drop it several inches. Another guy online with sagging original springs, or lowered but doesn't know the history, runs some measurements and replies with something like, can only lower it 1" if using that type of wheel, or whatever, the original guy goes out, gets lowered springs and new rims installed, isn't happy, it's nowhere near where he wanted and doesn't match the results he is told either. And so it goes.
