found a good deal on some semi-used koni's and was wondering what was a solid way to find out if they're still in good condition or even any condition at all. most people tell me to adjust it to the firmest setting as possbile, press the shaft downwards on the pavement, and see how fast the shaft rises. supposedly on the firmest setting, if the shaft rises at a fast rate then they are pretty damn good? any help would be appreciated.
