If you’re into fun-to-drive import performance cars but need the convenience of a 4-door sedan, it’s hard to find a better option than a Subaru WRX STI.

This car is familiar to anyone, as it’s been around since the mid-90s, but just like the good wine, it actually becomes better with time, and the WRX STi build we’re showcasing in this article is a perfectly illustrates this statement.

Symmetric All-wheel-drive

The all-wheel-drive layout and turbocharged boxer engines were the key elements that made Subaru stand out from the crowd of other import cars in this segment and gain astonishing results in the world of motorsports.

The combination of all these features along with a longer 4-door base provided the car with a range of distinguishing driving characteristics that are so much appreciated by professional racers and enthusiasts worldwide.

WRX (VA)

Just like its predecessors the 4th Gen Impreza WRX STI VA models has everything that we appreciate and love about these cars. The Turbocharged EJ257 2.5L Boxer engine provides 305 HP and 290 lb⋅ft of torque to all 4 wheels through a TY85 6-Speed manual.

The Build

Even though the car drives and looks exceptionally well, there’s always some room for improvement, and so the owner of this white 2018 WRX STI decided to tailor its looks and driving characteristics to his own vision.

Stance

The car sits just a few inches off the ground on a lowered suspension and a set of forged Work ZR10 wheels sized at 19×10.5 +23ET and wrapped in 245/35R19 Tires with Riviera blue custom painted brake calipers visible through the spokes.

Exterior

The XL CS Style front bumper and STi OE style skirts and spats, along with Varis style diffuser make the car look flush to the ground and give that ground-hugging sporty touch to the exterior.

To make the car sound right and gain a few extra horses, the owner decided to install a P&L Track Series Exhaust that provides a beautiful tone and enhances the performance at the same time.
