no tooling, rotors are really clean. I had vernier caliper (measuring tool) with me and the thickness of both the rotors were more than 23mm that is like when the come on a zero meter car.
minimum thickness is 21mm (mentioned"stamped" on the rotor)
more over, they are balanced rotors. I will show you the pictures. there is absolutely no vibration on high speed.
there was slight bit of vibration with OEM rotors.
