Protostar mod.

Hey I’ve seen it done before but I don’t know how to do it. How do you mod a protostar to take hubstacks?

Trade it for a PGM?

You’d have to punch out the caps, which I think are wedged under the rings. I think after that, you’d need to get a PGM axle and some additional components(I think YYE carries all this good stuff now). I’m not entirely sure though.
