    I have also been interested in the driveshaft for awhile but can't decide between carbon or aluminum. Both have there pro's and con's.

    Unless you plan to make 1500 HP, you don't need the CF version.

    I went with AL mainly because Pa is full of pot holes and I worried about knocking CF and spinning it off.
    I have an original one and have not experienced any problems.
    Anytime my car is on the lift at HHP
    I always ask how it looks. So far so good!!

    I will say my CF in the charger is a little noisy. Zero vibrations, just has a "whine" when easing off the throttle at highway speeds. I still believe it's a fine piece, but the wife hates the noise( and it's her car) so I'm thinking about trying the AL drive shaft.

    I always see the upgrade to an aluminum DS recommended on the sorts of threads titled, "Essential Mods for your HC," along with switching over to different wheel/tire combos, CAI upgrades, etc.

    Anyway, my question on the alum DS is: even if I'm not going to drag race or oval track with my HC, is it still a wise "minimum" upgrade to get for better handling, faster accelerations, and/or high-speed driving on highways, turnpikes, etc.?

    Fantastic upgrade...mine has been on the car about 2 months and no issues...bone dry underneath because my installer sealed the extra holes on the A8 shaft. You will get a very slight hum under very low cruise speeds, but that is normal with a one-piece shaft...the two piece shaft has a damper that absorbs all of the noise, whereas the one-piece does not. You barely notice it, and the SC whine quickly overtakes that. In the end, it is a MUST for anyone running more power than stock, or just putting DR's on a stock car and taking it to the track. The car just feels more connected.

    Also, all I had to add was a 1/2" spacer on the two rear hangers for my Solo Performance catback to safely clear the 4" DS. Readjust the tips, and it's perfectly aligned again.

    What if you intend to upgrade to different (better-than-stock) tires? Again, for street/highway use, not racing.

    For street use i still feel you would be fine. I feel the main issue is when at a drag strip and they have good prep meaning they spray a lot of sticky chemical down for traction is when the shafts are twisting. In both my M6 and A8 ive used full on drag slicks with no twist. I also have used drag radials with the A8 and no twist or breakage of the stock shaft. I did however put in the 1 piece AL shaft for piece of mind because i do race the car almost every weekend and do go to world class tracks such as Brainerd International Raceway which has some of the best prep around. If you don't plan on doing that i wouldn't change it out. This upgrade will void your warranty.

    Don't need to change OEM shaft as long as you are not racing. You can change tires OR rims.

    Thanks - although I thought it was only changing gears to 3.09s that voided the warranty, not the one-pc alum DS mod, no?

    Also, in a couple of other DS-related threads I looked at, folks were suggesting that if you have a 2016 MY HC, the factory already "upgraded" the DS (different PN than '15 Cats), so doing the DS mod really wasn't necessary.
