Driveshaft Shop 1-Piece Carbon Fiber Driveshaft 2015-2021 STI
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 850 WHP and 180 MPH. We 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 in the noise level in the car. By removing the factory 2-piece shaft and installing a single shaft, the car will feel more responsive due to the lighter weight of the shaft and also the fact that the hanger bearing is not moving up and down during acceleration. Available for the most popular motor/trans combinations, if you do not see yours listed, custom shafts are also available.
