Yeah, but with the R/T rotors your adding more weight too right?Here I am! :mrgreen:
In theory, you would get better stopping power from larger rotors, since you're clamping further away from the axis (kinda like leverage, in a way) - but that assumes the V6 calipers will fit on R/T rotors, like gameover said - and I can't see how they would.
Even if they would, and even looking at the theory, it's not going to be a big difference - probably not a noticeable one.
So you're looking at rotors and calipers at the minimum, but everything I've seen says that they swap right on.
