chuckstang said:ya why did ford go with 2 piece driveshaft? any reason?
and I heard dgussin has had problems with his one piece shaft rubbing because his is lowered.
This makes no sense to me as my 99 has one and is lowered with no problems but I know nothing about these new mustangs
?
Vibration and harmonics is indeed the reason as Ford stated. Your 99's driveshaft did not change its position when you lowered it because the center section does not move when lowered.
