This might not be the right forum for this question but I just have a few questions regarding this.
Is this something that the dealership should
install? I saw some sites that advertise, no
drilling and that it should fit into the vehicle's design without alteration.
What brands are better? Are the black ones going to chip over time? Do they become noisy when driving at high speeds? Will they rattle over time since they're not drilled into the vehicle?
