Our 2007 Impreza WRX STI is another example of our capability for various levels of tuning. This car is more mild than our Type-25 but still has the fun factor that will want you to keep on driving. Like all Subarus, this car has a charm that we like to keep. However, we go on to enhance the driving pleasure by adding a few minor touches here and there. With minimal horsepower increases, we focused more on the suspension and braking setup to make this car much more enjoyable.
