Ok ill post up my findings so far, The hex adapters for the terror came in, They did not fit, they are a hair too big, they would slide over the 19mm wheel adapter but would not fit into the 23mm gst rims. I took it to work and one of the machinists shaved off a few thousands off each flat on the outter edge till it fit really snug but not loose. The inside adapter fits tight also. I am still running in a new piston and sleeve so i cant really give a full bashing or heavy throttle report yet but they feel like sturdy plastic and with no slop i dont believe theyre going to break, When i checked one of my old wheels and old wheel adapter they do have a tad bit of slop in them which im happy to get rid of with this setup. I will update as i get farther along.
