Dhall1 - I will measure setup later this week. As far as parts I used 4.2 A6 quattro Race version of springs. H&R 29797-1 part

4everRS:

Ride is better than stock. Better than Street Setup (it was my prior setup). It is lower, look better and car handles more aggressively. I want to add Hotchkis swaysbars and call it a day. Overall it is much cheaper than coilovers, because our cars are heavy and in order to match DRC you'll need smth really nice, like KW3s.

Difference between DRC and normal shock is that there is a hose that wont let you take the shock home. You will have to keep the shock next to the hub. Basically it limits your working space. Other than that is it normal spring job.

Installation:
Always jackup both sides.
Top spring cups are held by one nut. Better to use impact gun to remove it. and socket with thin walls. Snap-on and similar wont fit in. I used cheap kits they sell in autozone or kragen.

-Front requires removal of 4 bolts (3 on top and 1 that hold the strut). Upper arms stay in spring cup. And of course you need to remove main long bolt holding 2 arms and steering arm.
-Back requires drop of LOWER control arm completely (4 bolts total) and 2 nuts on top.
TIPs: MARK alignment settings, dont forget remove headlight leveler nut on driver side, have spare jack available to lift arms after installation, have craftsman spring compressor (I used it for the front shocks), properly position rubber inserts between cup and spring or you'll experience different ride height, place all washers as they were originally.
