Ok, how do you detemine spring rates. I bought a pre-built car and the current springs have no markings whatsoever. The fronts are blue and the rears are a chrome color. These actually match what was on my old 240z but its been 10 years since I monkeyed with the springs on that car so I don't remember.

I've been going over katman's posts on suspension setup and looking to work with a baseline on the car, but that's difficult with unknown spring rates.

Are hyperco springs color-coded?

Where's a shop in Atlanta that can test spring rates? Landrums? Robinson Racing?
Thanks,
Tom
