I am presently getting my 2007 SRT8 rears going, doing a different front set-up, but am modifying the bracket to address what I believe are structual stress issues. I will have a set of front SRT8's for sale soon, the Jeep had only 70K miles on it and the rears I am in the process of re-building so I know they were in good shape. So no "experince" with performance ...yet...hopefully in a couple of weeks. Don't know the differences in such a new model concerning the bracket.
