I had Eibach springs (part # 2879.140 - a set for sale currently in the Active Threads
) installed when the car was about 3 months old .... they made the ride a little firmer, made the cornering a lot flatter, and gave me the look I was after
Yes, the AWD sits about 1" higher than a corresponding RWD model ... the extra fender gap looked horrible in my eyes and I had to do something about it as soon as I could
The SRT8 model sits another 1" lower than regular RWD models.
There's a member, on lxforums I think, that is using SRT8 springs on his AWD and it looks awesome.
There is also a coil-over kit available from KW, and another coil-over kit coming from Circuit Motorsports - a vendor on that other site
Hope I helped - I just saw this thread.
Also, click on the "my mods" link in my sig and you'll see all kinds of pics before and after the lowering
