... Is that the way of things when buying after market rotors?
The old rotor, properly removed without damaging the rotor carrier, will allow the new rotor to be bolted on securely. The new
look is pretty sharp and the install is common to most all replacement rotors.
To help prevent the
grooviness found on the OEM rotors, consider a new rotor with the vent holes staggered in such a design as to wipe the brake pads across the full surface of the rotor's contact area.
