If you already have the Mazdaspeed style spoiler for your 3rd generation Mazda 3 hatchback, it's time to elevate its look to the next level with CorkSport's "Gurney Flap" style Rear Spoiler/Wing Extension. This extension is four inches taller than aftermarket wings and wider than the competition which will make your Mazda the next social post. With seven hard mounting brackets, the wing extension securely holds the gurney-style flap in place, eliminating the need for unreliable double-sided tape. We manufacture our wing extension from robust 5052 Aluminum Sheet metal, which is powder-coated in satin black and mounted with tumbled finished Stainless Steel Brackets. The installation is simple and quick, providing maximum style appeal with minimal effort.

Designed specifically for the “MS” Style (Mazdaspeed Style) aftermarket spoiler for 2014-2018 Mazda3 hatchback.

Link to a step installation instructions for the Mazda 3 Gurney Flap Wing Extension

This wing extension adds just enough of what was missing from the MS style spoiler. Install was super easy, especially once you have that first middle screw in. Highly recommend a second person to push and hold it in the right place while you drill. Can be done in a half hour if you can focus on the task at hand.

Since installing, it has made the car look far more aggressive, to the point where I need to do some more visual mods to match! Even got some comments shortly after from some co-workers, so it's definitely noticeable from afar! I definitely recommend if you're looking for that missing flair on the rear end of these cars!
It fit perfectly on my Bayson R MS spoiler and looks amazing. This thing is HUGE compared to every other extensions you may have seen. It gave my car that extra bit of character that it needed. Install difficulty 0/10, took me about a half an hour with me being extremely meticulous with where I was drilling. Having an extra hand will make your life easier.
I do give warning, your mpg's will drop at highway speeds, around 3-4 mpg, regardless its still worth it.
First off, the aggressiveness of this gurney flap is extreme and not meant for the fate of heart, it is huge, but not in the way where the big ones hurt. But just the right size. We have this on our BaysonR spoiler (which is a speed 3 style spoiler) it went on perfectly, and it really gave the car a time attack look to it. It is a must have part for this spoiler.
