By subframe you mean the torsion tube mounting on the 944T? Agreed the subframe mounts, assuming everything mounts to one subframe, is probably good and safe if the can be done; I'm traveling and need to look at the subframe to see if that's safe when I get back. The primary difference between the 997S and 997 GT3 is simply that the rubber subframe bushings are replaced with aluminum, it increases NVH but reduces overall play. The 997 RS 4.0 goes on the replace the lower arm bushing with a spherical bearing, cuts camber loss under load, etc, the trick is knowing which bushing to replace and if it's going to do anything ugly.
