mine where already off when i bought the car bought im not too sure. But under the strips are white clips that hold them i think they are just stuck to the car with adehisive stuff. As for taking the strips off i dunno if you have to slide them off or pull them off. Im sure some of the other boys will be able to help you better Eventually if for some reason ya cant take them off get them colour coded like Nanglebadger did (Phil)
