Here’s the original link, but maybe creating a new post may generate more response.

I was wondering if someone can clarify some confusion I have. @jcardona1 bolt on setup is sweet and will be option 2 if I can’t figure out the issue I’m having. I want a slip on 5G4R rotor for ease of changing rotor later. According to 80.proof from instagram, user stated the length of the LC80 hub is good but the overall mounting face is too deep and too wide. I have no issue machining the OD of the LC80 hub smaller for the 5G4R rotor to slip over, but I’m not understanding the “too deep” statement. Does this mean a spacer is needed between the hub and rotor to push the rotor outwards to align with the 5G4R caliper? If so, anyone know what size spacer is needed? Or am I missing something?

Has anyone done this modification using the LC80 hub to utilize the 5G4R rotor as a slip on setup? I preferred a free spinning hub versus Trail Gear stud less hub as 80.proof posted.

Hoping someone has a solution.
