I have noticed that a lot of members here are using 100PCD alloys on their Fiat's. I know it is not recommended,but the options in 98 PCD are too less and options in100 PCD alloys are too tempting. Also i am not really aware as to how do you about PCD conversion from 98 to 100. Is the conversion safe? From what i have heard,issues like wobbling and questionable high speed stability come up. 100PCD alloy users,please post your views.
