The ACEPSTYLING "WINGHAMMER" ducktail spoiler extension is a unique design that securely mounts to the OEM Focus ST spoiler using four rivet nuts and double sided mounting tape. This is our first design of the Hammer series spoiler extensions (due to it's aggressive size and subtle lines). Our ducktail extension raises 4"s from the front of the OEM spoiler and 4.5"s from the rear. It wraps the full width of the Focus ST wing.  We designed our extension to seamlessly transition with the OEM spoiler lines from every angle. Our extension not only sits at a low profile 35-45 degree angle, but showcases an aggressive curve.

The "WINGHAMMER" wing extension has to be drilled into the OEM Focus wing and comes with 4 rubber rivet nuts, 3m tape, decals, and installation instructions. You will also have the option to upgrade your extension. Our certified PPG paint technicians will paint your part using our OEM color matched paint systems. Our goal is to provide the Ford community with a stylish alternative to a flat linear extension flooding the market. Our extension is made from high quality strong and flexible Fiber Reinforced Plastic. We also provide many more custom options to make each extension stand out from the rest. The WINGHAMMER extension is a great way to highlight the Focus ST OEM spoiler with some flare. Let other car owners know what Ford means to you! 

*Why you need this part today* Our easy to install instructions and unique designs are sure to turn heads and make customizing quick and easy.

• Our fiber weaved reinforced plastic construction grants stability and flexibility without sacrificing strength.

• Comes in a flat grey primer ready to be painted.

*Primer is only an undercoating prep for paint.

• Rare custom part sold nowhere else which creates a custom aesthetically pleasing appearance.

• Made in the USA

    Absolutely beautiful. Paint match is perfect. Fitment is perfect. It can be a little difficult to line up all the rivets after you've drilled holes, but once the fitment is right, they fit fine. Definitely looks better than all the aluminum extensions on the market

    The fit, the quality, customer service (customer service 5 Stars alone), color match, and paint quality are all top-notch. I only wish the rest of my car's paint looked this good. Thank you ACEP.

    Part fits great, shape is perfect, paint is trash. Color doesn’t match even using correct paint code. I ordered Oxford white. Paints finish is full of pits and fish eyes on top of being the wrong shade. They were willing to do a partial refund. I would have given 5 starts if I didn’t have them paint it. The part is very well crafted and fits amazing.
