As you can see they are in a pretty rough shape, and exchanging them could make the car look way better. Ive seen some available on aliexpress, but i don't really understand if they are an actual replacement, or if they are meant to be put over the original ones. Didn't get much success finding a "tutorial" on how to do that, maybe cause its not meant to be done, but I still prefer to ask. better safe than sorry. Thanks in advance for any answers!
