I don't know if my post was deleted or if I didn't give it enough time before I closed the window, however I don't see it nor any replies. After inquiring further I have found that in fact the valving is different and of course the warranty is as well. The other issue that I encountered is the requrement of the rear billet adapters ala 993tt's. I guess they have that same problem eating the rubber mounts. Can anyone confirm any of this data? I am just trying to get a kit that I have no problems with and is as correct as possible, even if I have to pay more and wait longer.
