I have my Koni's on 1 for now but will probably change it in the future. If you're Rallying you might want it stiffer.

There are a number of people on here that have changed their shocks to Eibach's. I don't have experience with those but don't feel the need right now to modify any more of the suspension (Yet!)

The Koni's are a little pricey but they make the SRT a comfortable car with out sacrificing the handling.
