The new motor makes way more power than before and in my experience

more power = something broken.

the clutch is upgraded to centerforce dual friction
the tranny has been completly rebuilt
beyond that the driveline is stock.

I think I need new Ujoints, axle shafts, and maybe driveshaft.

what do you guys use?

Just Ujoints ... IMO. The stock shafts should hold up fine.
If worried, you could 'upgrade' to the later year half-shafts which are larger diameter.

Nah..bite the bullet and buy the carbon fiber half shafts! :steering:

How much and where?

I have heard that the carbon fiber half-shafts are more of a High speed type of thing. They are perfectly balanced and work well at high speeds, however they aren't made for extremely high torque applications. This is just something that I' ve heard and you may want to look into it further before taking my word for it.

Doug..here is a site I found check it out...as you can see they do produce half shafts for looks like c4 and c5's, but they can also custom build shafts...here is the link http://www.pstds.com/carbonfiber.cfm Good Luck!
