The ACEPSTYLING "Leviathan" ducktail spoiler extension is a unique design that securely mounts to the OEM Mazdaspeed3 spoiler using four rivet nuts and 3M double sided mounting tape. Our ducktail extension raises an astonishing 4.5" from the Front of the OEM spoiler and 5" from the rear and wraps the speed3 spoiler from one side to the other. We designed our extension to seamlessly flow with the OEM spoiler lines from every angle. Our extension sits at a 35 degree angle, but showcases an aggressive curve that is sure to turn heads.

Our goal is to provide the Mazda community a stylish alternative to the flat linear extensions. Our extension is made from high quality strong and flexible Fiber Reinforced Plastic. All our products include detailed installation instructions and all mounting hardware. We also provide many custom options to make each extension stand out from the rest. The Leviathan extension is a great way to highlight the Mazda 3 aggressive style. Let other car owners know what Mazda means to you! 

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

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

• Comes in a flat grey primer or Gel-Coat ready to be painted. (Gel-Coat is another type of poly primer).

*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

SPECIAL REQUEST: Upgrade to ACEP's "OMNI FLEX" signature High gloss flex UV-protection clear coat adds durability and longevity. This clear last longer, provides better UV protection from color fading, has a flex additive to increase the paints flexibility to limit paint cracking over time or during application, this clear also provides a higher gloss finish over our “OREON” standard clear. (To Carbon Fiber or Painted lids only & three extra day delivery)
