I have an Audi 4000 (basically the same suspension as that on the newer
Audi 80), and have Eibach progressive rate springs, Koni shocks,
Suspension Techniques rear anti-roll bar, Audi turbo quattro coupe
front anti-roll bar, and custom fabricated front upper strut stress
bar.  The wheels are Ronal R8 15x6 wearing Fulda Y2000 205/50VR15s.

Yeah, and this is the reason why I bought a set of factory sport seats
(from a 4000S quattro) to replace the original seats in my car.  The
additional bolsters are most needed with the vastly increased handling.

Well, you can't have the cake and eat it too, can you?  Your newfound
handling performance came at a cost -- loss of ride comfort.  There is
really no magic to this.  In the case of my car, I think the ride is
actually quite good (as good as stock) as long as the surface imperfection
is minor.  If the bumps get any bigger, then it gets harsh pretty quickly.
This is an attribute of progressive rate springs.  I suspect your Bilstein
shocks aren't helping either, since Bilsteins are reknowned for their
stiffness.  If you feel that the ride is too hard, definitely go with
softer shocks.  The shocks would have more to do with ride quality than
the springs do.  I think the ride quality of my car is quite acceptable
considering the tremendous gains in handling.

Happy motoring...


P.S.  I n-e-e-d an Audi Avus.
