The nice CF parts are only a little bit cheaper. I am a big fan of KHZ, but some of the CF stuff is ver nice. (If you run KHZ knuckles, get a longer screw for the base of the knuckle or it could strip out. Happened to several people on truggyracers, as well as to myself.) The only think I ever broke was the c-hubs. That seems to be the weak point everyone on truggyracers found as well. I switched to aluminum ones but I do have 3 sets of hotbodies ones NIP. (And probably any other part you could possibly need.)
