Here is a tool for discovery RealOEM.com  Diagram Selection. This page is for standard suspension on your model, you can see the size differences for the sway bars, and the differences in part numbers for the struts and springs. When you want to see the JCW parts, select a different car in the upper left, select JCW among the options.
If you are fishing for user reports, frame your question in that context.
Thanks for the link. I will give it a try. I was planning on replacing the springs and rear sawy bar. I just wanted to make sure I wasn't purchasing something I already have.
