    I blew my diff at Daytona back in Nov. My poor Z has been down since then. Finally I got my new CF dirveshaft from Pfadt, its very pretty, shame it will be hidden away forever.

    Also got a new diff from RPM geared for road courses so I can explode out of corners

    Hopefully she'll be all wrapped up by end of Fed so I can strafe Moroso at PBSW

    how much stronger/lighter is a CF driveshaft? does it result in measurable performance gains?

    4# lighter and massively stronger. The stock unit has rubber mounts which will fail in high hp cars and racing. This one has aluminum mounts

    I'm no physics whiz but I imagine 4# off rotating mass should make a difference in acceleration

    Did you change the ratio in the diff?

    Yes, its designed to explode out of corners on road courses

    I dont care about top speed since I never use it

    I care about annihilating competition coming out of corners ;)
