I'm not sure, I kinda doubt it as I think the hardness of the ceramic is harder then the rings. When I 1st purchased ceramics for my Tc3, I was trying to find diffrings that mached the hardness of the balls. I ended up buying Niftech diff rings and using Acer ceramic balls. I'll be rebuilding my 12th diff this weekend using ceramic balls. I'm waiting for new rings to come in. Where the diff rings you used new?
