2006 ESX Impreza WRX STi
Easy Street Motorsports (ESX) have been making special editions of the WRX ever since it came to America. Their latest car is a limited production package that adds a more sporting touch to the WRX STi and mimics the cars they race.
What is most noticeable about the ESX package is the finely detailed exterior and interior. Each car features a hand pained stripe and striking two tone interior.
For performance enhancements, ESX upgrade the car to have 365 bhp and larger wheels tires and brakes.
Pictured above are the first three cars that were first shown at the 2005 SEMA show.
