Diffuser body is flush with the rear of the car and is designed specifically to match the rear bumper of the GV WRX and STI. The Railer (Jr.) is engineered to reduce lift (thus increasing downforce) on the rear end of your car by directing high pressure air to a low pressure environment (behind your car). All 5 fins extend the full length of the Diffuser to immediately start channeling air from underneath your car under your exhaust and straight out the rear of the car. The diffuser is mounted to the rear of the control arms and to the exhaust hangers using all-included brackets and hardware designed specifically for this diffuser. The rear brackets attached to your exhaus hanger are suspended with dense rubber grommets to prevent any vibration
