Another american tuning company has tried to modify a Subaru Impreza WRX. Perrin Performance tried to bring a lot of modifications to a WRX, from engine modifications, suspensions and exterior styling. The first step in their tuning process was installing a new, high performance exhaust system. Next, they’ve modified the engine cooling unit and now the car’s engine could develop 385 HP and a maximum torque of 540 Nm. The tuning process continued by installing new suspensions from H&R. As for exterior changes, the guys from Perrin added new elements at the car’s body kit. The front and rear bumper are wider and more solid now and those 17″ rims from Konig equipped with 245mm Yokohama Advan Neova tires match the car’s design perfectly.
