We installed Eibach lowering springs and sway bars (Pro-Kit) on Paul's Challenger R/T today and here are some pics ... This Pro-Kit was a great mod for this R/T and is impressive with really flat cornering. It's not harsh, but firm and a great ride!
Here's a pic of the kit as well ... More information: http://www.bmcspeedshop.com/product_p/2895.880.htm
