If the 300 AWD is like the Mercedes 4-Matic it is based on - don't hold your breath. There may not be any lower kits or suspension kits for the AWD. There are none for the MBZ 4-Matic cars. When I first saw the Magnum SRT-8 concept (Jan 2003) I wanted an AWD version to replace my SUV but then I found out it was based on the 4Matic - so I changed my mind because you can not lower a 4-Matic car.speedmeister said:eibach, mopar, or other. please post some pix.
