Delta Aztec 160mm 6 bolt Disc Brake Rotor
The Delta Aztec Disc Brake Rotor is available in 160mm. The Aztec Disc is a 6-bolt pattern and includes Torx bolts and wrench. Will fit any 6-bolt IS disc hub.
These seem to be good, cost effective rotors, but they have a LOT more braking surface than they need to, at least for my M596 Deore brakes. Only about 60% of the braking surface is used, which makes these a bit heavier than they need to be. The red paint on the edges does make them unique, and at least on my bike they look pretty neat.
