I got a Mike T disc brake set up and it all looked good until I tried to set it up. Everything is nice and solid but the spacer was not machined properly to fit over the stock 5 star hub. I put it in the lathe and turned it down 5 hundredths of an inch and it fits. On a side note, I noticed the disc is warped. If anyone knows how to fix that let me know.
The disc was warped when i had it sitting on a flat surface. But when i attached it to the hub and tightened it down it straightened out!
