Subaru has just released details on its range-topping WRX STI Spec C model, offered exclusively for the Japanese market. With just a mild performance increase the focus of the Spec C model is on better power delivery, handling and reduced weight. The new model is intended to be a more race-ready platform.
Engine output is 304hp and 311 ft-lbs of torque, up from the standard 295hp and 299 ft-lbs. The increase is slight but is the result of a modified turbocharger and ECU program that also allows for quicker response.
As for reducing the car’s weight, that has been achieved due to the use of an aluminum hood and a smaller battery. A plexiglass windshield and side windows also drop several pounds, as do new lightweight 18-inch wheels.
For improved handling the Spec C gets stiffer springs, a larger rear stabilizer bar, stiffer sub-frame bushings and new shocks. A new mechanical limited slip differential (SD) out back also improves the car’s ability to get all that turbocharged power to the ground. Reinforcements to the front cross member, new Bridgestone Potenza RE070 tires and increased power steering pressure result in better handling and driving feel.
The WRX STI Spec C will be offered in standard colors as well as two exclusive colors, Sunrise Yellow and Pure White. It is currently on sale in Japan with just 900 units being offered.
