Subaru Impreza WRX STi spec C Hits The Streets Of Japan

Subaru dropped the lighter, stronger, faster Impreza WRX STi spec C onto the Japanese market today, adding yet another ute to our list of grey market cars we’d do unspeakable things to import. Limited to only 900 units, the STi spec C is intended to give street racers (competing on a closed course with all the appropriate safety gear, of course) and concentrates the modifications on performance rather than aesthetics. The boxer engine (227kW (308 PS)/6,400 rpm, 422 Nm (43.0 kgf·m)/4,400 rpm) receives new bearings, an ECU upgrade, and inter-cooler water spray system that allows you to leave it in Sport Sharp without nuking the innards.

The suspension was stiffened, the chassis was reinforced, and the tires were swapped in favor of Bridgestone POTENZA RE070’s, all so that you can take that hairpin turn just a little bit faster than you should have, and make the the skid mark in the underpants of your passenger just a little bit bigger than it was.

Subaru Impreza WRX STI Spec C


•• Ball bearings of the turbine axle were newly adopted to reduce friction in the turbocharger. With the optimized ECU programming, the engine offers smoother and quicker response to the accelerator pedal and excellent accelerating performance.
•• An inter-cooler water spray prevents rise in intake-air temperature at continued high-load driving, providing stable engine performance and improved efficiency.


•• Reinforcement of the cross member in front-suspensions offers a linear steering response.
•• Specification changes in damping force of suspensions, coil spring rate, rear stabilizer and rear sub-frame bushes optimize rigidity for body roll and retain excellent road-holding capability.
•• Rear LSD (Limited Slip Differential) system was changed to a mechanical type from a Torsen type to obtain the steady and powerful traction during cornering.
•• Bridgestone “POTENZA RE070″ (245/40R18) were adopted to enhance cornering ability and higher grip performance, especially in dry conditions.
•• Nimble handling with a firm steering feel is assured by increasing oil flow volume in the power steering system.


•• An aluminum engine hood and a downsized battery, which make the front section of the vehicle lighter, produce better maneuverability.
•• Laminar glasses were adopted in the front and side windows. They lightened the upper section of the body weight, resulting in improved stability during cornering.
•• Newly-designed lightweight 18-inches alloy wheels are standard to offer excellent road-hugging property by reducing unsprung weight. (17-inches alloy wheels are optional)
•• A flat tire repair kit is standard, which also helps weight reduction.


•• A structural change of fuel pomp provides stable fuel delivery even on high-load driving.
•• Gold colored “brembo” brake calipers are standard.
•• The front bucket seats (fabric with red stitch) are standard on models with 18-inches alloy wheels.
•• The “RECARO” seats (Alcantara and leather combination with red stitch) are optional on models with 18-inches alloy wheels.
•• Two exclusive exterior colors are available; Sunrise Yellow and Pure White.
•• The production is limited to 900 units.
