I also called Ford Racing and was given more details on the kit. He did state that some of the parts had Euro part numbers. The springs are the M-5300-S that are already available on the Ford Racing Parts website. The kit also comes with both front and back Shocks/Struts, and both front and back stability bars. The bushings and all of the misc hardware is also included so that every piece is replace during the installation.
I will be giving Steve a call at Tousley Ford tomorrow to order the kit. The new ETA is 12 October 2012. http://tousleyfordparts.com
