I have ls mesh wheels too and i took off one of the center caps because i wanted to replace them. The front is held by glue and they need to be taken off with a flat head screwdriver but there not going to come off perfectly, more than likely they'll be bent. If you want to take the whole center cap out you need to take off the wheel and punch it from the back. Where did you get those si center caps and how do you know they'll fit?
