PST Carbon Fiber Driveshaft (15-21 STI)
Carbon fiber is the king of driveshafts. Carbon fiber is the lightest and strongest option. It will not rust, and the torsional strength is incredible. It is also the safest for the driver. If a carbon fiber driveshaft were to break, rather than producing jagged edges like aluminum or steel, the carbon fiber shaft will just result in loose fiber strands along the break (kind of like the end of a broom).
One major consideration for carbon fiber shafts is that they are not recommended for street usage (aka, cruising). The heat produced by prolonged street usage can break down the bonds in the carbon fiber shaft. We only recommend carbon fiber shafts for racing applications, not for your daily driver. For a daily driver, we recommend steel or aluminum.
FEATURES
- Made using strong, and lightweight carbon fiber materials
- Smoother launches as carbon fiber will twist, absorbing much of the drivetrain shock instead of putting all the stress on the differentials
- Improved throttle response, acceleration, and braking
- Weighs just over 14lbs
- Allows you to get to full boost sooner
- Faster response and greater flow than any other valve out there. (By more than 10%)
- Nickel plated brass fittings.
[NOTE] Due to OEM manufacturing tolerance, it may be necessary to modify or massage the underbody and heat/dust shields for the driveshaft to fit
