Of all the springs I have used during the years, I rate the -25mm Spax springs the most comfortable for everyday use. I found them slightly too low and I used spacers to lift the car which made it handle more level on track.
The absorbers I used were Koni yellows.
I tried standard shocks and lowering springs years ago, and it was totally terrible. Standard springs and Koni yellows are a rather nice combination on the other hand.
