all complet steet legal on STI  Subaru Tecnica International Inc. (STI) is a subsidiary of Fuji Heavy Industries Ltd. (FHI), which was established to undertake the motorsport activities of SUBARU. STI's core business is supplying motorsport base vehicles and competition parts and planning and developing SUBARU Limited Edition Models by applying special tuning techniques as well as planning and selling accessories and tuning parts to add variety to car life for auto enthusiasts worldwide. Through these operations, STI aims to provide its many SUBARU fans with special satisfaction. In 1972, FHI participated in the Southern Cross Rally in Australia with the first Japanese FF car - the Leone, before bringing out the Leone 4WD (the first AWD car in the WRC) in the Safari Rally in 1980. Following this, in order to respond to a new generation of motorsport with AWD turbo cars, which was expected to take off, STI was established in April 1988. Its founder and then president, the late Mr. Ryuichiro Kuze, was a board director of FHI and a co-driver in the Leone when it debuted in the Southern Cross Rally in 1972. As soon as he founded STI, he and his company planned and operated an event to challenge the world speed record in Arizona in the USA with the first Legacy which would herald in the future for SUBARU. In the event, the Legacy set a new world speed record for 100,000 consecutive kilometres of driving, a record which STI held for 16 years. This is how STI with its mission ‘to make SUBARU world number one', embarked on its journey as a brand which already was enjoying the world's number 1 title. After refining its AWD technology through a demanding Safari Rally, SUBARU began full-participation in the WRC with the Legacy, starting from Safari in 1990. STI's founder, Kuze teamed up with an up and coming British team to form the SUBARU World Rally Team the same year. Starting from the Acropolis Rally in Greece, the team competed under a new Japan-UK organisational structure, with the Japanese side in charge of engines and the British, the chassis. Meanwhile, STI's WRC activities for SUBARU led to the development of a car that could win in the WRC, and in 1992 this was finally embodied as a package - the Impreza. In the WRC, SUBARU clinched their first victory with the Legacy in New Zealand in 1993 before the succeeding Impreza came in 2nd outright in its debut event in Finland the same year. SUBARU made rapid progress after that. They finished the 1994 WRC in 2nd with 3 wins in the season. In 1995 and 96, they won rally after rally with an unstoppable force, and walked off with the WRC manufacturers' title for both years. As the World Rally Car regulation was newly enforced in 1997, the Impreza WRC, which had been developed in compliance with the new vehicle regulation, remarkably won 8 out of the season's 14 rallies that year to become the first Japanese car to be crowned as the WRC Manufacturers' Champion for three consecutive years. Released in November 1992, the Impreza was first used in the WRC in the mid stage of 1993. Although it already had 240PS as standard, it was required to introduce an evolution model to fight against formidable European rivals in the WRC. As a result, the WRX-STI was released in January 1994. Based on the WRX turbo model, WRX STI was equipped with forged pistons, a special ECU and larger muffler. With increased power to 250PS, this model was only built to order and the engine was fine-tuned by STI. Following a minor change in the Impreza in October 1994, an STI version was also released to much accolade. This STI Version featured the Drivers Control Centre Differential (DCCD) as well as a power increase to 275PS thanks to the reinforced cylinder heads and enhanced turbo boost pressure. Its success allowed the STI Version, which was then a limited edition model, to go into mass-production with its catalogue model from Version II in 1995 onward. Since then, the STI Version of the first Impreza - the GC8 type evolved into Version III featuring 280PS in 1996, and then up to Version VI released in 1999. While the Impreza STI Version, initially released as an evolution model for the WRC, continued to develop as a production car, STI planned a series of special specification models with even higher performance. The Impreza 22B STI Version, which was developed to celebrate SUBARU's three consecutive WRC Manufacturers' titles between 1995 and 97, was particularly revolutionary. Fitted with the same wide blister fender used in the Impreza World Rally Car, this model enjoyed a rush of orders upon its release in March 1998, and sold out immediately. As expected, this model enhanced the STI brand, and so STI took a big step forward towards its ideal - to become the figurehead for SUBARU. This direction of premium sport sedans in a limited number continued through the Impreza S201, which was released at the later stage of the GC8 type, and after the full model change of the Impreza in 2000, the S202, S203 and S204, which were all based on the GDB type Impreza. Following the full model change of the Impreza in 2000, the World Rally Car version's base was changed to the GDB type in 2001. Around that time, strong European manufacturers entered the World Rally Car field one after the other and the Impreza WRC improved its performance through competitions against these rivals. Driving the GDB type Impreza, Richard Burns became SUBARU's second WRC drivers' champion in 2001 - the GDB type Impreza's debut year, following Colin McRae in 1995. Then Petter Solberg won the championship behind the wheel of an Impreza, and proving the SUBARU is fast with anyone. SUBARU has won 47 WRC rallies - the most of any Japanese manufacturer; 46 of them in an Impreza, and so, this car now is known familiarly as a true world-class sport sedan among rally fans around the world. Furthermore, in another world championship, the PWRC where Group N cars of near-showroom specification compete, drivers in the Impreza won the title for 4 consecutive years from 2003, including a long-cherished world title for Japanese top rally driver Toshi Arai in 2005 - an achievement he then repeated in 2007. In rallying with Group N vehicles, which are closely based on their production model counterparts, victory cannot be guaranteed without good features in the original base model. While the Impreza WRX STI has established its position as a production model of FHI, STI's development department in close ties with FHI has introduced detailed specification changes at every annual revamp in order for the vehicle to be able to continually display high performance in rally competitions at a customer level. Consequently, the Impreza continued to make brilliant progress especially in the second half of 2000 in national and regional rally championships all around the world. In this way, the ever-evolving Impreza WRX STI consolidates and incorporates feedback and requests from the worldwide motorsport field. At the end of 2008, FHI announced its withdrawal from its WRC programme at a works team level. Following this decision, STI started to consider trying motorsport categories in which the company can capitalise on technologies and resources developed through the WRC to date. One idea was to continue offering their expertise to a GT300 vehicle in the Japanese SUPER GT series. Although racing conditions are different, challenges such as instantaneously delivering strong performance and maintaining durability and capability under harsh conditions are the same as in the WRC. Since the start of development of a new GT300 race car based on the Legacy in 2009, STI has utilised a string of ideas to develop the performance of the horizontally opposed turbo engine for a GT300 vehicle in conjunction with FHI and R&D SPORT which is in charge of team operations and car development. All these efforts paid off with back-to-back wins in the SUZUKA 700km and 500km races in August in 2010 and 2011 respectively in SUPER GT. STI has decided to bring in the following concepts into the development of their sport parts: tuning and setups, which make motorsport vehicles fast, are in fact the same as settings for safe and enjoyable driving for road cars: and smooth driving, which makes the driver feel as if their driving skills have improved, is another ideal. Based on the concept that cars which improve driving skills are cars which can realise comfortable and fast cornering without any difficulties rather than those which are on the limit making the driver nervous, STI also began focusing on the development of complete cars which accommodate parts designed for a ‘flexible yet elegant driving feel'. This direction developed into the ‘Tuned by STI' series after 2007 and then the tS series. In the meantime, the S series - the ultimate complete car in which a ‘flexible yet elegant driving feel' concept was pushed from pillar to post, and the R series, which realises racing style driving, have both been introduced and appeal to many customers. (STI Subaru Tecnica International Inc) MY2001-2005 with our CRTEK CRTEK the Chip-Racing power packs
