Stock Rear Spring Rate? Options

[detoxcowboy]

I would like to know the stock rear spring rate for a 74 914 2.0 w/ perforomance package.. the black springs with the green paint....

Ghetto spring tester for springs with a rate less than 300lbs/inch:

1. Place bathroom scale on bottom plate of press

2. Place spring on bathroom scale

3. Place scrap 2x4 on top of spring under press

4. Zero bathroom scale

5. Compress spring 1"

6. Read bathroom scale

Don't know how much difference it makes, but I read it is best to compress 1" to preload the sprig first, take a reading, then compress another inch and subtract the two measurements. Here's my ghetto spring tester i action. Would have been better to use a cheaper scale. These fancy electronic scales are only good for telling you how fat you are.

Yes, a good ol' mechanical scale is what I used. Stock springs aren't progressive so measuring just the first inch should yield the same rate per inch as the following 4". I recall taking measurements as far as the scale and jig would safely read just for giggles.
