Weltmeister Green Stripe

[jjone20]

I've got a set of 944 Weltmeister springs with no paperwork. They are marked with a green paint stripe. Anybody know what rating they are?

It turns out that spring rate of steel is pretty much a constant. Therefore you can use a spring rate calculator to figure out what you have. The more accurate you make your measurements the better the calculator works. Here is a link to one. Coil Spring Rate Calculations by Wallace Racing
You don't need to know the spring height. You can take an estimate of the front corner weight of your car and figure out how much the spring will compress and then figure out if your ride height will change.
