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 Roush rear spoiler comes pre-painted in Black. Paint code UA.

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.

5 Stars   Great looks and east to install.
By on 6/5/2015
Image uploaded by Billy H. Very easy to install, took about 1.5 hours. Only advice I'll give is put a stop on your drill bit to prevent the bit slipping once it breaks through. I wasn't paying attention and put a dent on the top of the trunk lid. Looks great, makes the rear look much better. Sporty but not too drastic.

Yes, I would recommend this item to a friend!

4 Stars   Excellent fit and finish. Missing Parts though....

Image uploaded by Robert B. Purchased the black painted spoiler and it looks awesome. Fit and finish are exactly how Roush would like it. My bag of hardware was missing the shouldered nuts that make attaching the spoiler to the vehicle much easier and quicker. Template used was spot on and attaching it to the car took 3-4 hours after going for a parts run.

Yes, I would recommend this item to a friend!

5 Stars   Perfect wing
By on 10/16/2016
Image uploaded by Aaron S. This spoiler looks great because it doesn't take away from cars lines, just accentuates it. More aggressive look but not over the top. Overall, it's an excellent addition to the exterior and I'm happy with it.
