I can't remember what brand rim they are hey.. they came with the car from Japan. They need a good clean and maybe a re-powdercoating but probably still cheaper then new rims. I haven't taken them off the car before either so I'm not sure on the specs of them.. tyres are 225's on the front and 255's on the back.
