There was no turning the rotor on this kit ... Simply install the relocation brackets and the rotor, and them machine/shave down certain parts of the caliper bracket.
As for the price, I believe the kit is less then a 100 bucks, without the rotors. That is about 50 bucks less then the NPG kit. Again, I am not sure what he wants for them. Get a hold of him on Facebook, work something out.
