A Dynamic Solution
Since we're going bolt-on crazy trying to squeeze as much e.t. out of this NA Coyote as possible (without going overboard), a lightweight driveshaft swap was a must. And when it comes to carbon-fiber units for the '11-up Stangs, The Driveshaft Shop knows a thing or two. It manufactures shafts in aluminum, steel, chromoly, and carbon fiber, and has been doing it over 30 years.
We chose carbon fiber for this build and took a behind-the-scenes look at how a carbon fiber driveshaft is made, being curious. The raw carbon-fiber tubing is cut to length, bonded to the billet ends (one end is a CV joint), and balanced at over 9,000 rpm, ensuring no vibration issues. We opted for the off-the-shelf shaft for our application (PN FDSH23-C-CV1; $1,249.99), but the company will build you a custom shaft for your street or race car.
