Side Bottom Air Deflectors/Strikers

[Eurasianman]

Do you need to jack your vehicle up or use ramps to install these? No. But would it have made it easier, most likely yes.

I just installed mine by turning the wheel. Talk about hand cramps. The passenger side took me ~10 minutes. The driver's side was 15-20 minutes since I had to use my left hand. And that's where I got most of the hand cramps. Also, not sure I saw it here, but a 7mm socket is what you'll need.

According to STEEDA.
These under body strakes, factory equipment on GT Performance Packs and Dark Horse models, help generate more downforce and improve aerodynamics, by channeling air out of the sides of your cars underbody, creating a lower pressure area in the rear helping aid downforce.

Engineered by Ford to improve the S650's performance on the track, these underbody strakes redirect the air flowing underneath your car and generate more downforce for better handling when racing. This upgrade is the perfect way to get improved performance at the track. Made from a tough rubberized material these strakes are resistant to underbody impact and will simply flex and return to position afterwards. See the video for more information.

I understand the principle, not sure if enough "channeling" will generate sufficient benefits. Again, at road course speeds, they just might do some good.

Ford is pretty good about shaving pennies off their costs. I suspect they found benefits in the wind tunnel.

I just logged into my account and saw this information. Thank you!

I recently picked up a 2024 Mustang GT with the performance package and found these strakes in the trunk. Thanks to y'all, I will install them on my car today.

Cheers!

Lugs and air deflector in the trunk that I found a few days later. I went back and they put them on.

Same thing happened to me. Just picked up my first ever Mustang on Monday. 2025 GT premium convertible. I'm now an X-Mopar Hemi guy and with no more Hemis it means no more Mopar. Absolutely love the Mustang!!! I found these deflectors in the trunk and the dealer says they will install them. I will likely never track the car so, are they necessary? Regardless, the dealer should have installed them upon delivery.

Wow…appreciate this thread.
Found these in the trunk in the 2025 I just bought. Sales guy didn’t know what they were. We tried to figure it out from the instructions with no luck. Going to have Ford put them on.
