I think that these modifications were done specifically by David...
Whether these modifications are carried forward into production? well thats a question which only Constant can answer. There are other pictures out there which subtle yet different front/back ends on the car.
For other queries that I have seen on this topic:
has a few pics.
photo 13, 14, 15 are most noticeable. (although there are others further on).
Also worth noting is that the car is seen with adaptors to use the associated/CRC wheels....
This may answer a few questions too...
I am a corally(aholic), and can barely wait to get my hands on one of these cars when they become available (in whatever guise).
I just hope that when it does arrive, that its correct. As one of the inherent problems with the SP12M is the rate of change of camber throughout the front suspension travel, thus making the car more unpredictable and giving slower corner speeds than the 12L4/CRC car..
Hope this helps.
