I feel the same. I literally don't have any drag strips near me, only twisty roads. Not gonna race stop light to stop light. And bought a manual because it's more fun even if it's slower. I feel like if you are that worked up about tenths and 1/4s you wouldn't buy this car. You'd buy a $5k shell...
Yeah I agree, middle are for sure screwed in. The bottoms could possibly be screwed but only way to tell is to take the front bracket off. Thankfully my dealer has a strict no drill policy after a bronco customer got pissed and made them find a new bumper in the height of the bronco shortages lol.
I think the biggest concern is getting it too hot for too long.
Also if it helps ease your mind my dealer has a policy no one can drive customer cars, not even the sales guys. Hope yours has it too.
The type of film doesn't matter at all. The percentage is a measurement of light coming through. Doesn't make a difference how much you think you can see "perfectly fine," 5% is just dangerous on first row windows. Especially at night.
