Found a much cheaper (possibly mass produced) rotor to go with my brake kit. 300mm diameter, 32mm thick. also remodeled a wilwood superlite 4 pot to go with the bigger disk and check for clearence, mostly goes well, though it is very challenging fitting such large parts inside the 15" wheel and between spokes and lca and not hitting anything. Also modified my alloy hub. Again, native support for the rotor, no separate bell. what do you think?
