The Genesis of a Rally Legend
The story of the 1999 Subaru Impreza WRX STI begins, as many great automotive tales do, with motorsport. Subaru's relentless pursuit of success in the World Rally Championship (WRC) was the catalyst. They needed a car that could conquer the demanding stages, and the Impreza, with its inherent all-wheel-drive capability, was the perfect starting point. The 1999 model year was a pivotal one, building upon the foundations laid by earlier Impreza models and taking it to a whole new level of performance and refinement. The STI version was not merely a cosmetic upgrade; it was a comprehensive package that included a more powerful engine, a stiffer suspension, upgraded brakes, and a host of other performance enhancements. The modifications were not just to make the car faster but also to provide more control and handling.
Subaru's commitment to rally racing directly influenced the design and engineering of the road-going STI. This focus on performance meant that every aspect of the car, from the engine and transmission to the suspension and aerodynamics, was optimized for speed and agility. This is why it still holds a special place in the hearts of rally enthusiasts and performance car aficionados. The result was a car that could tackle any road, a car that offered a driving experience that was both thrilling and rewarding. The Impreza STI's success in rallying, with its wins and championships, directly translated into demand for a road-going version. The 1999 model was a culmination of years of development, taking the best of Subaru's motorsport experience and translating it into a car that anyone could buy and drive. This is why it remains a cherished and sought-after vehicle to this day.
Unveiling the Specifications: What Made the 1999 STI Tick?
Let's get down to the nitty-gritty and examine the specifications that made the 1999 Subaru Impreza WRX STI a force to be reckoned with. Under the hood was a turbocharged 2.0-liter flat-four engine, a signature Subaru powerplant. This engine, known for its distinctive boxer rumble, was tuned to deliver around 280 horsepower and a substantial amount of torque. These numbers were impressive for the time, especially in a compact, lightweight chassis. The power was sent to all four wheels via a close-ratio five-speed manual transmission, providing blistering acceleration and exceptional grip. The all-wheel-drive system, a hallmark of Subaru's engineering, was further enhanced in the STI, with a viscous limited-slip differential in the center and rear differentials to improve traction and handling.
The suspension was stiffened and lowered compared to the standard Impreza, providing sharper handling and reduced body roll. The brakes were also upgraded with larger discs and calipers to cope with the increased performance. The exterior of the STI featured subtle but effective aerodynamic enhancements, such as a larger rear wing, to generate downforce and improve stability at high speeds. Inside, the STI boasted a more performance-oriented interior, with sport seats that offered excellent support during spirited driving. The 1999 STI wasn't just about raw power; it was a finely tuned machine, designed to work in harmony. Every component, from the engine to the suspension to the brakes, was carefully selected and calibrated to provide the driver with an exhilarating and rewarding experience. This focus on performance and handling, combined with the car's distinctive styling and rally heritage, helped to solidify its legendary status.
Common Issues and Maintenance: Keeping the STI Alive
Owning a 1999 Subaru Impreza WRX STI is an amazing experience, but it does come with responsibilities. Like any high-performance car, the STI requires diligent maintenance to ensure optimal performance and longevity. One of the most common issues is the head gaskets. The 2.0-liter turbocharged engine is known for its high-performance nature, which can put a strain on the head gaskets. Regular inspection and timely replacement are crucial to prevent overheating and engine damage. Another area to watch is the turbocharger. The turbocharger is a vital component of the engine, and any problems should be addressed immediately. Inspect the turbocharger for leaks, wear, or damage. The turbocharger requires regular servicing to keep it in tip-top condition.
The transmission and clutch are also critical components, especially if the car has been driven aggressively. Inspect the transmission for any unusual noises or difficulty shifting gears. The clutch may need to be replaced periodically, depending on how the car is driven. The suspension components, such as shocks, struts, and bushings, may wear out over time, especially if the car has been driven hard or on rough roads. Regular inspection and replacement of these components will maintain the car's handling and ride quality. The all-wheel-drive system is a key feature of the STI, so it is important to regularly check the differentials and transfer case for any leaks or unusual noises. Proper maintenance of the all-wheel-drive system ensures optimal traction and performance. Proper maintenance and regular servicing are the keys to keeping the 1999 STI running strong for years to come, allowing you to continue enjoying its raw performance and thrilling driving experience.
Boosting the Performance: Aftermarket Upgrades and Modifications
For those who crave even more performance from their 1999 Subaru Impreza WRX STI, the aftermarket offers a wide range of upgrades and modifications. One of the most common upgrades is a new exhaust system. A performance exhaust can improve the engine's breathing, resulting in increased horsepower and torque. Another popular upgrade is an ECU tune. Remapping the engine control unit (ECU) can optimize the engine's performance, allowing it to produce more power and improve throttle response. A cold air intake can also improve the engine's performance by providing it with cooler, denser air. This can lead to increased horsepower and torque. Upgrading the suspension components, such as shocks, springs, and sway bars, can improve the car's handling and ride quality. This is an important consideration, especially if you plan to track the car or drive it aggressively.
For more serious performance upgrades, consider installing a larger turbocharger. A bigger turbo can significantly increase the engine's power output. Upgrading the brakes with larger rotors, calipers, and performance pads can improve stopping power, especially if the car is used for track days or spirited driving. Installing a limited-slip differential (LSD) can improve traction and handling, particularly in cornering situations. Keep in mind that modifications should be carefully considered and installed by qualified professionals to ensure proper fitment and performance. The aftermarket options allow you to personalize your STI, tailoring its performance to your specific needs and desires. Whether you're looking for a subtle increase in power or a full-blown race car, the 1999 STI offers a solid foundation for modification. With the right upgrades, you can transform it into a true performance beast.
Preserving a Legend: Tips for Collectors and Enthusiasts
For collectors and enthusiasts, preserving a 1999 Subaru Impreza WRX STI is about more than just maintaining its mechanical integrity; it's about safeguarding a piece of automotive history. Proper storage is crucial to protect the car from the elements. Ideally, the car should be stored in a climate-controlled environment, away from direct sunlight, moisture, and extreme temperatures. Regular cleaning and detailing are essential to keep the car looking its best. Wash and wax the car regularly to protect the paint, and clean the interior to prevent wear and tear. Use a high-quality car cover when the car is not in use to protect it from dust, scratches, and other environmental factors.
Keeping detailed records of all maintenance and repairs is crucial for preserving the car's history and value. This includes receipts, service records, and any documentation related to upgrades or modifications. Sourcing original parts can be challenging, but it is often necessary to maintain the car's authenticity.
