This rear diffuser will definitely make you stand out from the rest with aggressive styling and quality above the other diffusers out there. Same design as our aluminum diffuser. Diffuser blades on stock diffuser are centered with the EMP diffuser blades for a clean professional look unlike the uncentered lopsided blades of our competitors diffusers. Easiest install of all the diffusers on the market with mounting holes (yes the competition has NO mounting holes so you just guess where to put the screws in), slotted attachment to two existing bolts to ensure center section is perfectly centered and adjustable to get the desired gap from rear of car. Comes with black stainless steel screws, nuts, bolts, brackets and stainless steel lock washers. Strong and remained steady during 155 MPH test - Lapped the Daytona 500 Race Track with one installed. Easy installation - installation video at bottom of page.
