  1. Quality Build

    By DJT August 11, 2022

    I bought two of these, and they still work and look great over a year later. They're not fading/ sun bleaching like I thought they might. Adds a great aggressive look to the rear.

  2. Stiff Wang!

    By JOE June 18, 2018

    So I bought a cheap Ebay STI wing for my wrx. (Dumb idea) it was cracking because it flopped around so much. Put two of these bad boys in and now it looks so much better! Plus you cant even tell it was cracked!

  3. Looks great

    By Marwan June 15, 2018

    I got two of them, Looks great on the car but not very easy task to install without a help, but overall I’m satisfied with it

  4. Brings out the car

    By Mr.WhoozyWhatsIt July 17, 2017

    I bought two, as that is the standard and I found the quality of the stiffies really nice. Thick and holds up really well. Comes with two strips of 3M each and they are longer than the stiffy itself so you will need to cut. I measured over three times and found the perfect fitment. Took about 30 min to find that perfect spot but after that it sits and looks amazing.

  5. Great Item!

    By Jose July 16, 2017

    These wing stabilizers are strong and they look great too. I surprised at the quality, I thought it was going to be a thin piece of plastic but it's not and it has a nice weight to it. Easy install. Thanks subispeed

  6. Great exterior addition

    By Roland January 13, 2017

    I purchased 2 of these and was able to put them on perfectly after measuring them several times to ensure that the space between them was even. Makes it easier to have someone pull up a little bit on the wing to allow space to fit the stabilizers in. Adds that additional touch to your exterior!
