The 1-piece driveshaft for the Subaru WRX Sti is a complete 2.370" Carbon Fiber shaft that is approximately 1/2 the weight of the factory 2-piece driveshaft. The 1-piece carbon shaft features larger, replaceable u-joints and can handle about 850WHP and 180 MPH. They had the tubing custom wound with a high modulus fiber to ensure the strength while making it small enough to clear everything under the car. All of the factory shields, plates and covers can be used without any alteration to the car at all. The ends are made from 6061-T6 aluminum and that shaft weighs a mere 12.2lbs. Not only will the car feel more responsive but it will also make a noticeable difference on the noise level in the car.
