Servotronic gets hooked up this week. I will post the results. So far so good. I like the S4 rack.
is the B7 S4 rack w/o servotronic heavier than the stock B6 A4 rack?

The servotronic work as designed. I agree that its a bit over boosted at low speeds. Once driving it feel perfect. Fine tuning will come later.
I thought it wasn't boosted at all over ~10mph or such. Or maybe that's just the RS4 version?
