Whad mods can be done to the propshaft on a Q4.. I've spoken to a few slightly more race\rally orientated mates & they have suggested lightening & balancing the shaft? I guess this would ideally be done along with the flywheel & clutch plate.
What do you think? what sort of cost is involved with this malarky?
If you are going to get anything like this done, make sure you go to a decent specialist, if you are getting the clutch done it is as well to get the torque splitter checked at the same time. If you are planning on going the modification route , you might want to consider a stronger clutch as well.
