There's a set of Eibach springs for sale in the Classifieds for a B6/B7 although I haven't looked closely to see they are correct for your specific model.
I have H and R lowering springs on my S4 and the height looks great.
Interesting. I've always found qst very knowledgable to be fair and they used to have a B6 S4 cab which they heavily modded. Saw it there once many many years ago. Nice looking car too. Maybe re mapping a B6 S4 is not their bag anymore.
Were you pleased with the JHM re map? Do you feel much...
