Should ride like **** with the 1.5:1 motion ratio squared in back.
Rear vert rate would be 222lb/inch.
Front you lose a little, so 130-ish.
If I had that much rate out back I'd want at least 250 in front to keep it from pitching.[/QUOTE]

So I understand, it sounds like a car with old black IPD springs is undersprung at the front? Where are you testing these springs? I live in Mooresville right in the thick of Nascar

I have a 1990 240 Wagon with black IPDs and Bilstein HDs and the ride is not great.
