Don't know about the "S" axles but I think the CV joints are from the 928.

Why so expensive? Supply and demand! Guess those axles just break too easy and the supply is drying up?
Seems like the consensus at this forum was that a 3.4l will need the more robust "S" drivetrain and brakes, especially when racing.
I don't recall reading whether the 5 speed tranny was really up to the task either when increasing the HP.
Maybe the expensive drive shafts are just the reason you need to upgrade to "S" parts.

Many owners with more powerfull than stock engines report the 5-speed is a temporary use part.

Are we okay sliding, hoping, and chirping on uneven pavement with the 3.2/6 speeds??
Once in a while I er.... em scrub my tires by sliding around....unfortunately it is a rough uneven pavement area. Thinking I should stop this!

2.7 986 Axles
Reviving this old thread, but I have a 2002 base model Boxster with the 2.7 and this is still and issue. The only option is to rebuild or pay big $$ to Porsche for OEM parts. Anybody know of a reman source ?
