I just bought some new chrome pillars and wanted you to see them. They are made with Polycarbonate. I was worried about buying them at first but I gave them a shot and they are a lot better than the stainless steel ones!They are cheaper and have a really long warranty on them. Here is a link to where you can buy some too!
