WRC graphics look great imo ..not that I would put them on my P1, but on a Newage YES ! - Use yellow rather than Day-Glo.
WRC body - Again very nice ...
Prodrive kit - Had it on my old WRX300, this car came with it already fitted (limited edition) I went up against Stephen (on the forum) three times at Crail, it was so so close on every run ...All stephen had done to his car at the time was a full de-cat and remap (fairly sure?) - cost would have been a lot less than what you will pay for the Prodrive kit, (and I might add, sound a lot better!) so on that note I can not really recommend it.
