The roof fins on the Evo work as an antenna as far as I know. Might look a little strange on a Corolla. I can get you a rare OEM 7th Gen Corolla rear window visor if you're interested:is it possible to get those spikes at the top of your window like how some tCs have and some Evos have? they look interesting... otherwise does anyone know where to get a rear window visor?
