Im not saying thats definatly the reason, it was a whisper i heard from a friend whos friends with team drivers. Its hardly sumthing that would be very public but would explain the reason for new arms, wishbone flex is never going to be desirable thing and especially without real high bite situations are you going to get much flex anyway. I cannot say definatly the reason for these arms and which is why i was trying to bounce ideas off people. What are other peoples opinions of WHY they decided to make these arms and market them as high grip arms!
