I took these off my six parts car. The springs are painted black with a red paint mark on one coil about in the middle. Any guesses or will I have to take them to the spring guy to measure them? Can they be rated without taking them off the Konis?
Thanks

Hard to tell but the ones I've seen with orange/red paint have been aftermarket 140lber's.
Factory used "yellow" marks for 914-6 and "green" for 914-4. They matched them and use anywhere from 1 to 3 marks on each (each spring would have had the same number of marks).
I have 140lb. springs with the orangish/redish markings.

Thanks Eric, but they weigh a LOT less than that!

CD's factory coil spring data pagetaking that data, and applying the coil spring formulas to what you've got, should get you in the ball park...

Thanks for the chart, but it only goes to 90#. Am I missing something?

that is the chart for FACTORY springs.
but using that data, and the formulas that have been posted here several times for computing spring rate from wire diamter, coil diameter, and free length, should give you a handle on estimating what you've got.

Aha....interpolate and calculate....I can do that. Thanks
