DSS Subaru 2008-2014 WRX STi 1-Piece Carbon Fiber Driveshaft SUSH9-C

This is the Driveshaft Shop 1-piece carbon fiber driveshaft specifically made for the 2008-2014 Subaru Impreza WRX STi. If you're pushing your WRX STi hard, especially with modifications that increase power, the stock two-piece driveshaft can become a weak point. This upgraded unit replaces the factory setup with a single, strong piece that's also significantly lighter.

The primary benefit here is the carbon fiber construction. Carbon fiber is well-known for its high strength-to-weight ratio, meaning it's incredibly strong without adding much mass. This reduced rotational mass can lead to a slight improvement in throttle response and can help reduce drivetrain vibrations, especially at higher speeds. The driveshaft is designed as a direct replacement for the factory unit, meaning it fits right into the existing mounting points. This makes installation more straightforward compared to custom setups. The Driveshaft Shop is a well-known name in performance drivetrain components, and this driveshaft reflects their focus on building robust parts for demanding applications.

When installing a new driveshaft, it's always a good idea to check the universal joints and center support bearings on the transmission and differential ends to ensure they are in good condition. This driveshaft is designed to be a direct fit, but always refer to the manufacturer's installation instructions for any specific torque values or procedures.
