They give you a lot more access to different settings, which gives you a wider range to work with than just some filters.
Here are a couple pics of my new design, based on the MotoGP Safety Car for the BMW 1M. I built this from scratch, and it took a few hours. Its missing some manufacturer sticker because they just don't exist. Anyway, let me know how I did! (design is available in the storefront)
