aluminum drive shaft

ok maybe when yall guys are done complaining about power increase or MPG. How about this my U-joints went bad car went nuts on me. So what the heck the dealership was gonna charge me 300 for a stocker for my cobra. So i bought the alum. FRPP. Wow what a difference a lot less vibration in the car its smoother makes the undercarriage look sweet next to all the rest of my Stainless steel stuff. Its a must if your DS or U-joints ever goes out on you.
 
People upgrade to a aluminum for any of the following reasons:
1) switched to a tremec and require a different yoke (standard on the FMS alum)
2) have experienced vibration after installing taller gear (higher numerically)
3) believe that it is easier to spin and will pick up HP :rolleyes:
4) Find it too expensive to replace a bad DS with a new OEM
5) Want to be cool like their friends
