I was wondering if someone was still riding that horse.
And, actually, as of July 2013 that statement is false.
According to the brushless motors list posted at Roarracing.com, the Trinity 13mm are at the very bottom of the list of approved rotors.
With that said....
It will add a good amount of torque and take away rpm hence less top speed.
You can gear up to compensate.
13mm in a B5 overkill?
Not as long as there is adequate grip.

Thanks on everything else though.
