Saw this thread and remembered your post over on 6Speed:
http://forums.rennlist.com/rennforum...-for-sale.html No affiliation with seller. You may want to check it out along with some discussion on seat mounts. There have been some pretty negative comments regarding the safety (concerns) of the knock-off seats. At the minimum, I'm not too impressed with the color selections of the ROTtec seats. (I do have the factory ones.) Also, the leather quality of the Euro GT3 seats is definitely a grade above the stock seats.
