Thanks again for the replies. I don't know for sure if these discs are TUV/DOT approved or not. I just can't find anywhere that they are. Perhaps some others would have the answer? I know that the insurance point of view that your friend talks of is sound. Would you insure something that has been modified with potentially inferior parts? I thought not. Maybe I should email the company, Tri net and ask them right out.
