Things will be a little tighter with the Gen 3 seats Mike. I have them in my 01 GTS, which has custom mounts from Northwood I believe. Getting in and out is a bit harder because of the tighter clearances, but they do feel much better than Gen 2 seats once you are in. I can drive for a few hours and my back(which is not great) is better off than even my daily driver LS430.
