Product Description

Roush Styling
Change the look of your 2015-2018 Mustang with this Roush rear spoiler! Roush was inspired by racing to add this aggressive look to your S550 Mustang. The factory deck lid has a bit of a duck tail lip on it, but it could really use a little bit of an extension. This Mustang rear spoiler from Roush will really set your S550 apart from the rest! Roush has notched out this S550 rear wing for maximum rear visibility. It is made from light-weight and durable ABS plastic. ROUSH spoilers are designed and manufactured using OEM CAD data and manufacturing processes, guaranteeing optimal quality and perfect fit. Installation requires no sanding or trimming and is frustration free with the inclusion of templates, hardware, and high strength adhesive tape.

This Mustang spoiler comes pre-painted from Roush in Ruby Red. Paint code RR.

The ROUSH spoiler is not recommended to be used as replacement on a vehicle equipped from the factory with a spoiler. There will be exposed holes in the deck lid if the factory spoiler is removed and this spoiler is installed.

Cannot be installed on a convertible as it will cover up the 3rd brake light.

-Fits 2015-2018 Mustang Coupe WITHOUT factory spoiler.

Image uploaded by Matthew S. While the spoiler came in looking great.
Read the great directions twice to make sure we would have little to no problems. So all tools gathered up to make for a quick install, was about the quickest it went. layed out templates, taped them in place. Drilled all the holes. Then the problems started. I will say that the fit was less than desirable. The spoiler was less than straight, I have installed numerous body parts and spoilers. I knew i should have tried to dry fit before we drilled. Then the funny part of Watching two 230lb+ men try and rebend the spoiler straight just to try to get it to fit. After two hours and lots of effort the spoiler is on. They dont tell you that the holes you drill will fall into the truck lid. Still trying to figure how to get those out. NOT real happy with the fit. But, there will probably be only two people that truly know how much of a Charlie Foxtrot this truly was and is.

Image uploaded by Chad W. Great fit, relatively easy to install. The downside is the Ruby Red does not perfectly match. It is a little noticeable in direct light that the Roush Ruby Red is a different shade. If I were to do it again I'd go unpainted and have a body shop match, as I'm slightly disappointed with the color match. It was the first thing my coworker noticed in direct sunlight.

Yes, I would recommend this item to a friend!

Image uploaded by Adrienne E. Installation was a breeze and simple. Only took about 2 hours at the most as long as you follow through with the instructions step by step. Looks great on my car giving it a sleeker and more aggressive look. Very impressed and would highly recommend to anyone that wants their S550 Mustangs to stand out!

Yes, I would recommend this item to a friend!
