There definitely is a market for a track day only car. I've done a fair share of track days and see more and more folks moving to the manufacturer stuff, most often the Porsche GT4 clubsports. More competition in that space is surely a good thing.
Any word on transmissions for the R & S? Expect it will be the 3160 manual but thinking perhaps the TR-9070 DCT 7-speed dct might be an option.
Also wondering what abs system will be included as seems to be weak link on the fp350s.
