STI PERFORMANCE PARTS
STI is the monastery of performance philosophy, a think tank of driving theory, a university of automotive principles.
A vehicle that’s easy to drive safely at the limit in competition is a vehicle that can be safely driven on the streets. High speeds and the duress of competition are the ultimate tests of quality. Competition is the proving ground of our technology.
The basic formula hasn’t changed for decades. Low center of gravity and high traction—both made possible by the Subaru engineering constant—the horizontally-opposed SUBARU BOXER engine coupled with Symmetrical All-Wheel Drive.
An STI vehicle is designed to be so intuitive and confidence-inspiring that it feels connected to the drivers’ nervous system. In competition and at the Nürburgring, STI vehicles are known for beating more powerful cars. Why? Because STI vehicles empower drivers.
The seeds of STI were planted in 1972, when Subaru campaigned the Leone in the Australia’s Southern Cross Rally. After their first foray into competition, Subaru made history with the first AWD car entered in the World Rally Championship (WRC), when the Leone 4WD entered the Safari Rally in 1980.
By 1988, with the competition reputation of AWD and turbo cars established, it was time for Subaru to stake its claim. STI was founded and they quickly made a powerful statement by breaking a world speed record. Led by Ryuichiro Kuze, the STI team smashed the a new 100,000-kilometerworld speed record(Effective as of the end of April, 2005), driving Legacyat a blistering average speed 138.780 mph (223.345 km/h) for 447 hours, 44minutes and 9.887 seconds, continuously.
True to STI’s philosophy that racing and production vehicles go hand-in-hand, the WRX STI was released in 1994. Based on the Impreza WRX, the WRX STI brought rally-proven technology to the masses – the turbocharged SUBARU BOXER engine coupled with the Driver Controlled Centre Differential (DCCD) and Subaru Symmetrical All-Wheel Drive.
With the rally course claimed and conquered, the tarmac was our next challenge. The 24 Hours Nürburgring was chosen. A grueling 24-hour team race, it would be a great test of STI engineering and philosophy.
The tight and precarious Nürburgring Nordschleife circuit played right into the strengths of the STI racecar, a vehicle that could easily be driven safely and confidently over the 24-hour duration of the race. This is an event rewards consistency first, outright speed second.
The STI race team won the SP3T class of the Nürburgring 24-Hour Race in 2011, 2012, and aims to return to the top of the podium in 2014, proving the effectiveness of infusing “Enjoyment and Peace of Mind” into the STI NBR Challenge race car, a quality that can be felt in every Subaru around the globe.
The Subaru Impreza 22B STI is one of the rarest and most sought-after Subaru vehicles. Only 424 of these vehicles were produced and it was designed to commemorate Subaru's 40th Anniversary as well as the third consecutive manufacturers' title for Subaru in the FIA World Rally Championship (WRC).
The limited edition S206 was created to push the limits of performance while retaining the soul of the WRX STI it’s based on. With substantially improvements in feel, maneuverability and overall performance over the production WRX STI, the S206 is hand-built with top-grade STI components. Built to commemorate the STI team victory in the 2011 24 Hours Nürburgring race, the NBR CHALLENGE PACKAGE featured a carbon roof and carbon rear spoiler.
