Up F/S are (4) Kartboy polyurethane speaker spacer rings for your front speakers. Each spacer measures 0.500"X5.70". Most people put two of these together for each side to allow an extra mounting depth of 1". By doing this the you can pretty much mount any 6.5" speaker components for the front of your car. These are *Brand New* and have never been used. I ended up trading in my '07 STI before I got a chance to install a stereo system in it. I'm looking to get $35 shipped for all (4). Please PM or Email [email protected] if you have any questions.
