Looking for a good rebuilder that can do a complete thorough rebuild not just the nose cone. I'm new to this and have been told the rotors need to be aligned or something and wondering if there are any upgrade parts recommended. I've tried for weeks to reach pse superchargers to no avail as I understood they were the Toyota rebuilder. I saw superchargers online claims to be the only Eaton authorized service center which is who I've heard made the original ones. Interested in personal experiences with this particular unit.
