Car appreciation... the aesthetics, the engineering, etc

Cut the ends down on universal ones if you don't want to fracture your skull and put yourself in A+E when you get out of your car and forget they are there.

Also noisy roof bars, wrap thin (3-5mm) nylon or dyneema (climbers always have this stuff on their person) around them tightly in a spiral, shuts up just about every noisy roof bar ever.
