2015+ Subaru WRX/STI Gurney Flap by Jen Speed Solutions
The Jen Speed Solutions Gurney Flap adds aggressive styling to your low-profile trunk spoiler. Without looking too intrusive, the Gurney flap modification adds a small amount of height to your existing spoiler for a clean, clearly modified look.
The Jen Speed Solutions Gurney Flap is constructed from 10g 6061-T6 plate aluminum to eliminate corrosion and rusting. Precision laser cut, slotted holes allow for alignment adjustments during installation for a perfect fit. The Jen Speed Solutions Gurney Flap has a small enough profile that rear visibility is virtually unchanged. After installation, the third brake light assembly still sits higher than the gurney flap. Installation of the Jen Speed Solutions Gurney Flap is easy with our step-by-step instructions and addition of our included threadsert hand tool. The Jen Speed Solutions Gurney Flap does require drilling into the existing low-profile trunk spoiler and the final look is definitely worth it.
After sending the Jen Speed Solutions Gurney Flap in for professional flow analysis, it was determined that it decreases overall lift of the car while only slightly increasing drag. This means the aerodynamic efficiency of the system is increased.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all.
The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day.
They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable.
Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.

The best no show socks
The only no show socks I have ever found that do not slide down. These are very comfortable and the extra tab on the back provides comfort by keeping shoes from rubbing the back of your foot. The top of the sock also comes up high enough to cushion the top of your foot all while still remaining hidden while wearing tennis shoes or even with my hey dudes.
