Subaru further enhances the WRX STi line-up by introducing in Japan this STi spec C model, in addition to the regular WRX STi model and STi A-Line model, the AT version.
The WRX STi spec C model features enhanced engine and chassis performance as well as a lighter body on the premise of driving in motor sports. The twin scroll turbocharger newly adopted ball bearings for the turbine axle bearing, and the ECU (Engine Control Unit) program was also exclusively tuned. Thus the engine of the spec C model increases the maximum torque, and provides quicker response and improved accelerating performance. The adoption of an aluminum engine hood, laminar window glasses and a downsized battery resulted in a lighter body, which further refines the model’s driving performance.
