Why Choose RW Carbon?
We know there are many companies out there claiming to have the best carbon fiber upgrades for your 2015-2018 Audi R8. At RW Carbon we take the time to quality control every single spoiler that ships from our warehouse. When you order from many companies online they are shipping a product straight from overseas that has not been quality controlled. If you order one of these parts you could receive an trunk spoiler that is damaged, has scratches in the clearcoat, or overall poor carbon fiber construction. By choosing RW Carbon we make the promise to deliver you a consistent, quality product that is shipped from our Southern California location. Additionally, all products shipping from our warehouse are meticulously inspected, and packaged to ensure you receive the best possible carbon fiber item for your Audi R8 V10 Plus. We welcome local pickup of nearly all of our items in Southern, California.
