there should be a white sticker on the inside of where the door closes, there are pics somehwere on the forums. The recall can be done by anyone, original owners or 10 down the line it dont matter. there are few guys that have fitted Unichips, there is an emanage or 2 on some of the 1zz-fe rollas and myself and xoom have fitted Power FC's, all of witch help with the low end, some more then others. some of the guys that are running the stock rims can step up and shed some light on the tyre issue.
