Nero, your file is broken. Could you post it again?
Certified, have you gotten your car on the ground with a reasonable expectation of the final weight yet? I would do that before I sweated the springs first. Having said that, I found in my notes where I had 10" 150# springs and was able to get the ride height (measured behind the front wheel) to 5 1/4". My notes also say that the spring perch was up a bit over 1" so it should have been able to lower it about another 1/2" (assuming the shock is at a 45° angle). Now, my memory was that the nose of my car was higher than I liked at the time (I like the way the S2s sit lower) but my notes don't address that. Currently, I have 8" free length springs but my rate is 250#. My ride height in the front is 4 1/2" and I like the stance better. So far I haven't had any problems with bumps but I haven't had them for that long. I'm experimenting so that may change (hell, everything may change!).
As an aside: My meager understanding of suspensions deflates when considering the Europa front suspension because of the way the front springs are pre-loaded so until the load on the spring exceeds the pre-load, there will be no suspension deflection. I guess the effect is to reduce the effect of weight transfer to the front?? The rears are not pre-loaded. In my short racing experience, I don't recall any race cars with this type of pre-load situation. Maybe someone can help me understand the implications of the pre-load.
