it's a good mod if you plan on putting alot of power to the ground. the stock drive shaft tends to twist and bend a little on high torque engines. it is also lighter than the stock shaft which decreases the rotating mass.

It depends on how much power you're looking to push and which trans you're running. If you have an M6 and you're looking for low 1.5 60' times, then I'd have a custom DS built by Denny's. FWIW, unless you have an A4 w/ 2.73's, you have an aluminum DS. The CFDS doesn't weigh much less than the aluminum one, and it shouldn't be bought to try to get more power to the wheels. The carbon fiber unit is stronger, and that's the only reason you should really consider one IMO. Some look for added power due to less rotating mass, but it's not anything you'll notice unless you have a steel DS.

Will save some weight vs an aftermarket DS from other places.. but the prices are like $700 vs 400. I am running the stock steel one, but will be getting a 3.5" chromoly one soon.

I think most of the weight improvement comes from lightening your wallet... <img src="graemlins/gr_cry.gif" border="0" alt="[whiner]" />

Hmmm...I guess everyone forgot to mention that driving a CF DS on the street is an accident waiting to happen. And I bet the car in question is not a trailer queen, it is driven over little rocks. These little rocks become flying CF chipping debris. As soon as the CF is chipped, cracked, frayed...it becomes the death trap. By the way, can't you get a chromoly DS from denny's for about $400??? Sounds like the best idea even for that trailer queen!!! <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" />

Death trap waiting to happen huh?! I don't think so. a CF driveshaft is far superior to Aluminum and steel when it comes to safety. They don't stay in one piece when they take a hard impact, insted they just desintagrate into a plume of fibers. Thats why in mnay cases your not required to use a driveshaft safety loop when using one. It's built in safety. Shure it might beat up the underside of your car a little, but at least you won't flip over and considering that safety loops don't always stop the driveshaft from falling I would feel alot better. Also a CF drivshaft doesn't permanantly deform like a metalic driveshaft does, and it's more resistant to torsional forces, and dampens vibrations better so it actualy does put more power to the ground, not to mention that it's still lighter than the lightest aluminum driveshaft for our cars, and nothing even comes close to how much smoother the ride will be.
As far as reliabuility goes, if you not insepecting the driveline of your car before pushing it your really asking for trouble. CF driveshafts don't really dent, but the epoxy coating can chip off and cause problems if it isn't repaired. It's easy enough to repair though, just buy some DevCon epoxy and patch the chiped area. I've know plenty of people who have had CF driveshafts on thier street/strip cars for a few years now and none of them have had any real problems. I would say it's worth the money.

I've had my ACPT for over a year now and no problems. I wouldn't but it for power but for strength and how smooth it is.
My ACPT CF driveshaft weighs 9lbs, and my stock aluminum weighs 14lbs. I think the steel driveshaft weighs 21lbs.
I bought it because my previous car was an A4 that had 2.73's with the steel driveshaft.
You guys should click on Tony's (Nine Ball) link in his sig and look what happened to his aluminum driveshaft. Twisted it in two like a soda can.
Peace,

Umm, have you seen or felt a carbon fiber DS in person? No way in hell those little "rocks" are gonna ding this thing, especially in a low car like the F-body, with the DS tucked up under the car, and the exhaust partially blocking its view. Carbon fiber is not that easy to ding or chip, this sucker is HARD.
