Tom's SC430 and the FXX seem to be just releases of the regular TA05 chassis.. since the Porche is a commemorative release for their 30th Anniversary, I think this chassis setup will just be for a limited time..
Just looking at the description, "Special Chassis based on the TA05" with a 230mm wheelbase, I think it'll be a one-off.. they may use the carbon deck in a release for the future, but for now they just wanted to make it really special with CF and aluminum bulkheads..
Being with no other hop-ups, I doubt they intend this to be their R or Pro version..
For that price, you might as well get a 415MRE to race in GT1, but with the CF, aluminum bulkheads and motor mount it'll look pretty sweet..
Cantilever spur shaft?? Looks like they REALLY want to shave off that extra aluminum in the middle..
