Rest assured ford did plenty of R&D, they did their job, your stock driveshaft wont explode on you going under 80 or WOT or racing. I have taken my car up to 100 and past with no vibrations or shudders in the drive line. If you want to play past 115 then get a new ds especially if you have 3.73 gears.
I'm not arguing with you, because I don't know the facts... but where/how do you claim that? I have heard the exact opposite more than once on these forums, so once again... how do you know?

Anyway, I agree with the rest of your post, until/IF I get 3.73's I won't be changing out my driveshaft, not because it's not smart, but because I rarely street race, haven't been on the track, and only occasional go over 100... not to mention, if a stock 305 horsepower car can't handle 100 MPH speeds, then I'd say the entire car is a POS and not just the driveshaft! (I know, that's a ridiculous statement to make, just having fun). But yeah, if/when I do tune/gears, I'll probably do it along with a new DS.
