Aluminum 1pc driveshaft vibration at speed

Sorry to be the bearer of bad news but you going to want to get ride of that driveshaft. The driveshaft is resonating at certain speeds and can not be made big enough not to. There is a huge thread over at my g37 com about it. Best you can do is get a carbon fiber one, but it is pricey. I have the carbon fiber one and it is the next best thing to do after a lightened fly wheel.
