I am going this route for my 2008 WK as well. It's in Steel Blue Metalic and Mopar never did this color for my kit so getting primed kit.
How are you and other people dealing with the rear bumper? I think to make it look complete and right the bumper will need to get done. There is a rear bumper srt8 package. Here http://www.justforjeeps.com/srrebupa.html
Issue I have is that I also have your Magnaflow exhaust too and want to keep that. Just wondering with the rear bumper package what would needs to be done to change and make come out the center of the bumper plus costs associated.
I will be getting the front and rear srt8 springs to drop as well.
I already have 20" wheels and tires for mine so good to go there. I want my WK to have the SRT8 look and heading in that directions with these mods.
Appreciate feedback and help on the rear bumber and exhaust situation
