On these springs...
I answered my own question by calling Eibach... and after much delay, got on
the phone with a tech person.  Here's what he said:

Anyone who got a set of springs labeled 1517.002 for the rears, got the wrong
rear spring.  The new number (that I received from shox.com this week) is
1516.002 for the rear spring.  EVERYTHING about these two different rear
springs is identical (both spring rates, coil diameter, wire diameter) except
the 1516.002 is 30mm shorter unloaded and unsleeved.  The free length of the
1517.002 was 335mm, while the "correct" 1516.002 is 305mm.  This explains the
1970's "jacked up" look that myself and others have noticed.

He also reviewed the chronology of Eibach springs for the urS4 with me.  He
claims that nothing (in terms of spring specs) ever changed for this spring
set, US or German.  The only difference was where they were wound, some here,
some in Germany.  The confusion started in the US when they offered Pro Kit
Dampers, on which the rear perch problem existed.  For this, they offered the
spacer.  Otherwise, he claims that they are currently offering the ONLY
spring kit they have EVER offered in any country.  Part numbers have changed,
but the specs have remained identical, according to the specs he was reading
to me.

So on that note... If you bought a 1529.140 Pro Kit from anyone, and it has
1517.002 rear springs, he said that Eibach would replace them with the
correct springs.  He said those folks should call Eibach at 909.256.8300 and
talk to Scott Curry at extension 130.

Hopefully this will help some folks with Eibachs sitting in their garage.
Take care,
