I pulled a set of yellow springs out of the rear suspension on my 914. They are the same height as the new 140lb weltmeisters I am putting in - in fact slightly shorter. Any body know what they are - can you tell from the color?
thanks steve
Full Version: what are yellow springs?
Tells me someone had some yellow paint on hand...
To measure the rate of a spring, put it on a bathroom scale, and step on it to compress it one inch. What the scale reads is (approximately) the rate of the spring. This may be a problem if you're 180lbs and they're 200lb springs...
If the wire is the same diameter all the way along the spring, and they're spaced evenly, it's a linear spring, so you can also compress it half an inch, and multiply the scale reading by two to get the rate. Solves the 200lb spring/180lb tester problem.
If the wire varies in diameter, or the coils are not evenly spaced, it's a progressive spring, so this test won't work all that well.

actually, measure the spring length. subtract one inch, and keep adding weights untill it reaches that length.. Stepping on a scale will give you an inacurage measurement because of the springs in the scale bouncing...
mmmmm, Twinkie flavored springs 
with some degree of success, you can also do a google for a spring calculator in which you enter the known measurements of said spring (number of coils, diameter of spring...etc, etc....)
