while searching a few sites I found a CF drive shaft . They are supposed to be lighter and stronger, it also said that by swapping to the cf the car will be able to accelerate and decelerate faster. I think i understand the reasoning behind that but does any one know to what degree accelaration and deceleration will be changed and if the bennefits of making the change worth the 900 or so dollars it sells for?

i know i didn't give a spicific brand name and that they may be different ones out their. any info is appreciated.

 

what brand name?

 

dont know the brand name, if u know a brand i'd like to know about that one. I was asking about cf driveshafts in general.

 

I would be surprised if you could measure any difference by installing a CF driveshaft. Save your money for something else.

I would be careful, we ordered a carbon fiber driveshaft for our hybrid turbo deisel/electric explorer and it turned out to be heavier than the stock one. I would make sure beforehand that if you aren't satisfied with the weight that you can send it back for a full refund.

^^The stock FD DS is pretty light.

 

do you know how light ?

 

it's hollow aluminum. I would rather spend that money in reducing friction in the tranny.

 

i believe the stock s5 t2 ds is around 14lbs.

 

I think Wael Dasher had the carbon fiber drive shaft from ACPT and it is indeed lighter. There were also a few that had failure using this drive shaft on high hp 7's at the strip. I'd use one road racing if I had the funds to blow on one. Wouldn't be THAT much of a difference but considering harmonics and drivetrain shock, it's quite a bit better than a hollow aluminum drive shaft. There have also been issues with yolk seperation from CF shafts on other applications. No idea if they were ACPT shafts or not. Essentially the aluminum or steel pieces came "unglued" from the shaft itself.
