Considering the following to go with Koni FSD:

Criteria: Not too low but lower and stiffer than stock sport/s-line.

vogtland: cheap, 1.2" drop
eibach: 1.2" drop, sold bundled with FSD
neuspeed: 1.2F, 1.5R (too low?) but bundled with FSD = cheap!
h&r: 1.3" drop

Unaware of any others.

b/c I don't believe its a good option with S4's. Just wondering b/c I am looking at A3's right now and man these things need a drop!

I personally stay away from non height adjustable setups.

Want a slight but noticeable drop over stock sport, slightly stiffer springs (for protection from bottoming and performance).

I'm pretty sold on the FSDs as they offer a unique compromise.

I just don't know enough about the different brands to know which the relative spring rates and drops.

or use somebody's lowering springs. Looking for info; I'd like to end up an inch or so lower than stock sport height, with improved suspension compliance and handling - nothing radical or tracky. I may end up with soft coilovers.
