I thought you may all want to know the conditions that the NOTUBES aluminum rotors are made for. I was surprised after three races, two of which were muddy races, that these pads AND rotors wore to the point of having to be replaced. I wrote the NOTUBES company and received the following reply:
I note in the instructions that my pads will ware real quick in muddy conditions. Most of the pro teams will use a steel rotor and stock pads in the rear and my aluminum in the front in real muddy conditions. In the mud we use mostly rear brakes.
Some stock pads will not last one race in the mud. My pads will usually last two or three muddy races. But if used in dry conditions the pads will last about one year.
Rotor life should be 1 to 2 years.
I have designed them with eight holes so they will fit on the standard 6 bolt and also 4 bolt hubs.
Power should be similar or a little better than stock stainless rotors.
The pads will also work well on stainless rotors.
The pads are organic and may squeal on long hard continuous braking but the squeal will go away after a few stops.
Pad life will be greatly affected by wet and muddy conditions.
Rotors may squeal more than stainless rotors when wet.
Pad life is quite well they should last 6 months to a year.
There is little or no brake in time required.

The instructions NOTUBES is referring to is on the website was not present in the package I received from NOTUBES. As a final note the website states that the pad lifetime is greatly reduced in muddy conditions so check your pads closely after each muddy ride if you use this system. Don't end up like I did with a $220 disc rotor/brake pad replacement system that lasts three rides that I can't use.
