Hi! I have a question about the RRC cars. I read that they have only 29 mm restrictors and yet they compete in the same RC2 class as R5's with 31 mm restrictors (IIRC)... where do they make up the competetive advantage?

I have also read that Msport brag about their RRC's being convertable to full spec WRC cars in around 6 hours and I have understood that RRC's are meant for regional championships which really makes me wonder. Are they WRC spec cars with R5 aerodynamics and a smaller restrictor (ie less engine but more cornering)?

...and how does the DS3 RRC compare to the Fiesta RRC?

Sorry for posting it here, but there was no "Rally general questions" or "other" category.

Cheers
