Drive shaft angles do play a role though. The straightening effect that shafts tend to have do also create drivetrain bind and can affect the way the car rolls through a corner on power and the way it accelerates.

When the drive shaft is swept back, like most cars, this will tend to make the front end stay flatter under power, while if they are swept forward, they will make the car lift the front a bit more.

John Stranahan played around with this quite a bit a long time ago with his XXXS. I am sure you can find a bunch on it in his thread if you search for it in his XXXS tips and tricks thread. He used to say swept back was good for mod and swept forward was good for stock.
