The Subaru Impreza WRX STI Spec C, based on the Impreza WRX STI, has got several improvements and was launched in Japan lately, with sales begin this week. Only 900 models will be built and it's not clear that whether the Spec C will be available in other markets.
One of the important performance enhancements on the Spec C is a newly tuned Engine Control Unit, which includes enhanced engine and chassis performance as well as a lighter body derived from the automaker’s motorsports program. The turbocharger also gets new ball bearings for the turbine axle bearing, and the ECU program was exclusively tuned. These changes result in a torque to 422 Nm, while the power still maintains 305HP.
Subaru also optimized the suspension, springs, and fuel pump. As a result, the chassis offers stable and linear driving control even when traction reaches its limits. Meanwhile the rear Limited Slip Differential can be switched to a mechanical unit to improve traction in the corners. Furthermore, the adoption of an aluminum engine hood, laminar window panels and a downsized battery resulted in a lighter body, which further improves the model’s driving performance.
When talking of the weight, the Subaru Spec C features an unspecified weight reduction, previously rumored to be in the range of 70kg.
Besides, 18-inch lightweight alloys wheels come standard with the addition of a flat tire repair kit instead of a full-sized spare, and the 17-inch alloys are available as an option. The wheels have seven double spokes, and are wrapped in Bridgestone Potenza RE070 tires which improve cornering, and increase grip.
The car comes in two new exclusive colors: Sunrise Yellow and Pure White. Other standard equipments include gold Brembo brake calipers. Alcantara and leather mixed Recaro seats are available as an option.Source URL: https://carrevieeeew.blogspot.com/2009/07/subaru-launches-new-impreza-wrx-sti.html
