Whether you believe it or not, Solid rear diff mounts plus a one piece DS will add quite a bit of NVH.

I've taken off my Fall-Line CF DS, and sure the car doesn't react instantly, but it's way easier to live with on the highway.
不同Fall-Line一樣。 他們的DS還有振動,我們沒有了

As outlined in the review on the 1st post, there is low/minimal amounts of vibration, even when the driver consistently drove over 100mph and onwards, upto 140mph

There are only a handful of companies in Taiwan with the ability to manufacture complex components (not your cheap lug nuts, wirecovers etc) in 100% dry carbon, with all of them either only dealing with oem's (e.g car manufacturers, aerospace etc) or contracted to governments/military. Of these, there are only 2 in Taiwan that makes the driveshaft tubes for the aftermarket performance industry. They only make the carbon part of the driveshaft, and they are both very good at it (and both products look identical, because they use the same type of machines).

However, they outsource the manufacturing of the flanges/joints, and this is where the issues lay. It is the customer that determines the cost of the part, not the manufacturer; A manufacturers responsibility is to do what they are told. There are literally hundreds of companies in Taiwan (or thousands if you include China) that can machine these parts, but less than a handful with the correct machines that can machine a BMW flange/joint, not to mention within the oem BMW tolerances.

All but one will only deal with oem's/high-value clients, as tooling costs to do this is not cheap as the tooling needs to be imported from Germany. Although our carbon tubes are sourced from one of the above companies, the difference is we make our own flanges/joints in-house as we are that one company, and as we are offering our own branded driveshaft, no competitor has access to our flanges/joints i.e They either have to order flanges/joints from another specialist factory in the thousands (in our niche market, not going to happen), or resort to the cheaper alternative (and thus have issues with fitment and/or vibrations).

This is the difference between ours and Fall-Lines, regardless if they look similar or not
