Details
The 1-piece carbon fiber driveshaft for the Subaru WRX STI is a complete 2.370" 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. DSS has 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 and covers can be used without any alteration. The ends are made from 6061-T6 aluminum and that shaft weighs a mere 12.2lbs.
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.
NOTE: This driveshaft is rated to 850WHP and a top speed of 180MPH and is not recommended for use above this speed. The stock flange on the vehicle will need to be modified to accept the 10mm bolts. This allows the driveshaft to have its extremely high rating.

By Gregory March 31, 2019I've seen several videos where folks remove the exhaust, not necessary. I had no problem working around the exhaust pipes. Remove the heat shield and you're in business. The stock drive shaft is 20 something pounds but disconnects relatively easy. The big thing with this is part is drilling the holes larger on the flange. Start off with a 3/8 (9.5mm) drill bit and finish it up with a 13/32 (10.1mm) since it's impossible to find metric where I'm at. It took me about 30 minutes, this is the hardest and longest part too. I used a zip tie to hold the new driveshaft in place so I could get the bolts in, then tighten down. You will feel the difference immediately, I fell in love with her all over again.
