    I reached out to QA1 today about their CF drive shaft and recieved a prompt response with the following info when inquiring about weight and daily driveability:

    The driveshaft for your car is P/N JJ-21216. The weight is 21 lbs. including all mounting hardware and adaptors. Our driveshafts work great on daily driven cars as well as competition applications. The newer Mustangs, Challengers and Camaros all tuck the driveshaft up in the tunnel above the exhaust and heat shielding so they are pretty well protected from road debris. We also offer driveshaft for dirt circle track applications that are constantly being hit by rocks and debris from the track and these stand up very well. We also have driveshafts in year round use in test vehicles here in Minnesota and have not seen any issues with heat, cold snow or road salt.

    Interesting enough I was looking at the Shaftmasters site and didn't see one for the 2018 A10 so I reached out to them to confirm. If that's the case the decision may have become easier for me at least.

    Heard back from Shaftmasters. They confirmed they do not make one for the 2018 A10...

    Due to 10 speed automatic trans vibration/shifting issues we have been reading about on forums (i.e.mustang6g.com)
    We currently do not offer shafts for the 2018 GT Auto.

    So that is that. QA1 appears to be the way to go at least for me with the A10.

    Very cool! Let us all know how the install goes and the results. Curious to know how much quicker it revs and if there is indeed no added NVH.

    Also, I'm loving the Steeda CAI I bought from you, with E85 tune it rocks!

    Planning on installing same time as the DSS half shafts to offset the weight some, and for less parasitic loss to the wheels simultaneously. Quicker revs just a plus as well as future proofing for possible fi.

    Glad you're liking it ! I bet it's a beast on straight e. Was just a no go for my flex requirement lol.

    Awesome good call! Plan on doing the same in the future. Those DSS half shafts are definitely stout! Shouldn't have any issues there. And I think it's fine they're heavier, any weight right over the rear tires is a plus in my book.

    So when I ordered the CF ds I didnt realize it was not in stock. The materials to build it were supposed to arrive 4-20 (today) so will see when it actually ships out.

    Another vote on the Shaftmasters ALU. I've had mine on for a bit now, 100's of track passes and ten's of thousands of highway miles. They seem to stand the test of time. Not the same platform I know but might be good feedback....

    What kind of performance gains do you see with this aluminum ShaftMaster? Seems like an easy bolt on modification that I haven’t thought about.

    Not sure theyre really "performance gains" but here's what I noticed/why I did it.

    1. Feels much more "direct". Hard to describe but for instance when downshifting and accelerating the power/acceleration is now instantaneous. There was a small delay with the 2 piece driveshaft. It's not noticeable until after you feel the one piece lol then you will see what I mean. It's definitely a good thing.
    2. Less rotational weight so theoretically less stress on the trans and less power lost to drivetrain loss.
    3. Stronger and wont break under added power, especially for track use.

    How much lighter is the shaftmaster? The CF versions are not much lighter than stock

    I believe they are 9 or 10 pounds lighter. Doesn't sound like alot but rotational weight is supposed to be worth alot more than regular weight.

    That’s good. The CF shafts are less than 10lbs lighter than stock which is odd.

    When I replaced my stock 18 A10 with the QA1 CF, I didn’t weigh each of them, but it felt like a pretty good chunk of weight difference. I guess it could have been 10lbs but felt like more. ????

    Plus the NVH with the QA1 CF should be noticeably less than the aluminum in addition to the weight. Hoping mine ships this week sometime.

    I ordered a QA1 for my 15’ manual back in December to replace the DynoTech I previously installed and I finally got around to installing it last week. All I can say is wow what a huge difference over the DynoTech. Absolutely no NVH (in my opinion) and it feels like the power hits smoother, almost like there isn’t the initial shock that you feel with the aluminum. If you consider the cost over the aluminum I feel it’s worth it.
