The RRCs are buildt as a WRCar, and they then put on a different flywheel, restrictor and smaller spoiler kit.
So the main differesnce btw R5 and RRC is not power, that are pretty similar, it is in the bits used in the rest of the car IMO. The RRCs are more durable in all aspects of the car than the R5s that are buildt with cheaper parts to keep the cost down.

(if this is completely wrong technically, there will be a couple of CZ boys correcting me... :-))
