NFSC Car: 2006 Subaru Impreza WRX STI
The Subaru Impreza WRX STI (formerly STi, officially changed in 2006) is the highest standard-edition trim in the Subaru Impreza line.
The WRX STi continues on relatively the same. The Impreza line's looks have been updated.
The WRX STi Spec C's receives the Arai tuned dampers and a 21-mm swaybar. The rear suspension is changed from rubber bushings to pillowball bushings. The strut tower was further stiffened for improved handling and stability. The strut towers were reinforced for better handling and better ride characteristics. The engine mounts were changed from metal to liquid-filled plastic mounts to reduce vibrations into the car's cabin. Some 2006 owners have had issues with these plastic engine mounts. The manufacturer will replace them, under warranty if broken, with the 2005 rubber mounts.
The DCCD is updated with the use of a torque-sensing mechanism inside the DCCD. The torque split is changed to 41/59.
The WRX STi Spec C was used for Group N homologation.
