Either way, seriously don't go over thinking or beating up anything, at the end of the day they just work, ROAR will be the icing on a nice bit of gear.
Dont worry about the KV rating, most of those numbers are based on manufacture timings, and their speedo. Once you start mixing and matching who knows what you are going to get.
Saying that, all ROAR approved STOCK motors are very close in construction, and performance.
Also, if a motor has a lower KV, and is not revving, then you just need to run a different gear. its WATTS that you want, not RPM. You just need to figure out the gear required for the quickest lap time.
