Subaru’s WRX STI spec C hits the streets…but only in Japan. The spec C model is lighter and has a few engine enhancements to separate it from regular STIs. The ECU has been retuned and the turbocharger has new ball and axle bearings. Oil flow volume to the power steering system is up, lending the spec C a firmer steering feel, according to Subaru. The rear LSD has been changed to a mechanical type to enhance cornering.
Front and rear suspensions have been tweaked and Subaru says body rigidity is improved, too. Plenty of measures have been taken to reduce weight, starting with an aluminum hood. A smaller battery, laminar windows, and a flat tire repair kit replacing the spare tire help reduce weight an unspecified amount.
The 18-inch wheels are standard, but 17-inchers are available. Regardless of which wheels you choose, only 900 are available. Sunrise Yellow and Pure White are exclusive to this model, though you can also get it in blue. Gold-colored Brembo brake calipers are part of the package.
For those in the USA that can’t get a Spec C, I guess you will have to beef up your STI from our Performance Subaru Parts Store.
