The channel EverythingApplePro decided to replace the front and rear brake pads on a Porsche 911 with iPhone 5S and 4S handsets. That means eight in total.The group decided to test them on a stretch of road at 20, 40, and 60 miles per hour, though the front right wheel area caught fire after they attempted to stop at their first marker of 20 miles per hour. In the end, they went through with the 60 miles per hour, but had to use the emergency brake.
