Yes I agree the 3:55s would have been much better gear over the 3:15. My 2016 Roush Mustang had 3:55s and it was perfect setup with the 6 speed automatic.
I love the look of your coupe!
My 2025 gt mustang did this today while I was working on the back of the car. I opened and closed my door any they finally went off by themselves.
i have only owned the car for a couple of weeks. This was the first time.
