My very crude assessment of some standard old springs put them in the 80lb/in range not the 70lb/in suggested but it may be that these are European rates that are typically higher than American rates (did VW have a softer suspension for the US market?)

If you have coilovers with 2 1/4" springs you could get progressive rate units wound or a dual rate with a version of stiff helper springs at say 75lb/in plus something over 100lb/in. The final rates of course will be determined by the actual corner weights especially for a Scooby powered bug.

Warning, I'm just learning this stuff!
I came across this page below:

By 80-100Hz did you perhaps mean 0.8 - 1.0 Hz? as suggested by this page or is there something I'm missing?
