Subaru WRX STI Parts & Accessories

How the Subaru WRX STI Became Every Enthusiast's Dream

The Subaru WRX STI is a legendary high-performance machine that trace its origins directly to the grueling world of international rallying. Introduced as a standalone performance model in the 1990s, the STI (Subaru Tecnica International) variant pushed the boundaries of what a small sedan could achieve on gravel and asphalt. Its influence on car culture is immense, fostering a global community of enthusiasts who appreciate its mechanical, raw driving experience.

What Sets the WRX STI Apart From Other Performance Cars

The heart of the WRX STI is the high-revving 2.5-liter turbocharged Boxer engine, which in its final iterations produced a staggering 310 horsepower and 290 lb-ft of torque. This powerplant is exclusively paired with a reinforced six-speed manual transmission, offering a level of driver engagement that is hard to match. Performance is enhanced by the Multi-Mode Driver Controlled Center Differential (DCCD), which allows the driver to adjust the torque split between the front and rear wheels.

The STI's Symmetrical All-Wheel Drive system with front and rear limited-slip differentials provides world-class traction in extreme conditions. The interior features deeply bolstered Recaro performance seats designed to keep the driver secure during high-G cornering. It's also worth noting that the STI has claimed multiple class wins at the 24 Hours of Nürburgring, proving its durability under the most intense racing conditions.
