I would think that the R will come with the new axles...which are what I use.
The thing is, in other parts of the world they are LEGAL for other series, and I think that it is mainly aimed at those regs, not ours.
It only takes 2min to do, and its more a case of car performance rather than worrying about taking 2mm off each front axle.
I'd rather have a realy good car and take 2mm off the axles, than have a naff car that fitted in the box.
