What Sets STI Vehicles Apart?

So, what distinguishes an STI-tuned vehicle from a regular Subaru model? The answer lies in the upgrades and modifications made to the vehicle’s components.

STI vehicles typically feature a more powerful engine, with a turbocharged four-cylinder engine being the standard. The suspension is also tuned for maximum performance, with stiffer springs, upgraded shock absorbers, and anti-roll bars that help to keep the car planted on the road. Larger brakes are also commonly found on STI vehicles, providing better stopping power and reducing the risk of brake fade during intense driving.

In addition to these upgrades, STI-tuned vehicles often feature aerodynamic enhancements, such as a rear spoiler or front lip, that help to reduce drag and increase downforce. These enhancements, combined with the vehicle’s other upgrades, result in a car that is not only faster but also more stable and agile.
