Will this type of product increase top speed?

If so how would a track owner/race director tech a vehicle?

Errrr........ there have been different rotors available for other motors for a few years now, this isn't anything particularly new.

Different rotors will alter the power band, making it more torque-y, more rpms, a narrower or wider band - depending on the rotor - so yes 'some' will increase the top speed, others won't.

AFAIK, all these rotors (and others from different manufacturers) are perfectly legal for mod classes, so no need to tech them.

If you're looking at 10.5/13.5/17.5s, then just measure the diameter of the rotor and the shaft.

I think this is a Brand commercial action when they stop selling brushed rotors. I don't see nothing from other world.

The spec classes have very specific rules about rotors. This is for mod, and all it's going to do is alter the feel of the motor to better suit whatever surface you're racing on.

Yes, you could probably put these in spec motors, but that's cheating.

As others have said, rotor options have been around for a couple of years now. All Orion is doing is putting them in a package so they can trick you into buying 4 at once, rather than individually.

Adam, Novak asking $30 for one rotor felt like a trick to me, so this isn't even the first trick.

The bigger diameter magnet will offer lower Kv rating, but with an increase in torque. For example:

A 3.5T with 12mm magnet will have a Kv of around 10328, with a 12.5mm it's around 9156, 13mm it's 8449 and 13.5 it's 7913.

(The above Kv ratings are for my motors and others will be different)
