Great to see another vendor for DGRR!! Any photos of the scalloped rotors?.. What's the benefit of a scalloped rotor?

 

Like the rx8's rotors, it helps to advance the timing along side porting. May be a little "safer" than port work since you could kinda make the ports a little smaller with the same effect. That would be my best guess.
