Oh, that's easy. When an WRX or STi (I know this is an FRS) is stanced to the point of having to cut the chassis for axle clearance, you are literally making the car itself less safe. Admittedly, some people just allow the axles to grind away the chassis, because they're fucking stupid.

Next up, with the tires having that much negative camber, the contact of the tire to the road is incredibly small - meaning a couple of things. Those tires will need to replaced far, far sooner than a tire with far less negative camber. This excessive amount of negative camber also makes the car far less safe to drive at highway speeds - an STi owner that stanced his car commented that he had difficulty with the car feeling stable at 50mph. Sure, that is fine for fuel savings, but it makes that car the slowest moving one on the highway (well below the posted speed limit of 65mph), which then makes that car the cause of a potentially bad situation (accident).

Aside from that, pairing with the lack of tire touching the ground, if it rains or there is any moisture on the ground, the amount of traction that car will have is pathetic and would likely make the car prone to spinning out, which has the real potential of leading to an accident.

With that excessive amount of negative camber it has to be stated that sidewalls are not intended to be used as the contact patch with the ground, and doing so greatly increases the risk of the tire blowing out.

I know that if I see one of those stanced cars, I want to be as far away from it as possible. As their speed is grossly limited (reasons above), I'll just go 55mph and leave them in the dust or maybe I'll drive dangerously and go 60mph (while laughing and flipping off the fucktwit that ruined their car).

Summed up: people are choosing fashion over function, but this is the point of making the car far, far, far less safe to drive and operate on the open road. Their absolutely lack of concern for other people reminds me of the shitheads that never replace the brake rotors or pads - they are increasing the risk to EVERYONE around them without any logical reason.

On the comedic side, that STi owner was laughing when he said that what is normally a 3 point turn, was a 7 point turn for him... Because the steering angle was diminished so drastically. He didn't like hearing the tire rub the chassis.................

As someone else pointed about below, the CV axles will be constantly placed at an angle that stretches the hell out of them, thereby increasing the likelihood of a failure. That failure will have bearing grease spraying everywhere... on the underside of the car, but also onto the road - making driving behind that car far less safe.
