Na dont bother, just take the sticker off the back windscreen. Makes it look like you're trying too hard. Sorry hate to say it.
third brake light is on wired to factory wiring under parcel shelf, easy to take off. made a mistake using sikaflex to stick it because it wouldnt stay on, it wrecked my tint. , but if i were to take it off for the rear spoiler then i'd re tint the windows but i would end up doing them all darker
springs sag to much because of all the weight in my boot. and it kept scraping on a friends sliding gate thingey so bags was the right thing to do.
