Is it the area of the spring, where it would be the 175 lb rate?(coils are closer spaced at free length)
It will probably stack all the lighter coils before raising the car, giving you essentially a 350 lb spring and probably a rough ride.
I am assuming this because 175 lb seems fairly light. I know I ran 225 lb on my 69 Firebird and will be switching to 275's when I get it back out.(someday lol)
