Why Choose RW Carbon?
We know there are many companies out there claiming to have the best M3 and M4 carbon fiber upgrades. At RW Carbon we take the time to quality control every single front Lip 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 lip 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 BMW. Choose RW Carbon for your GTX style parts and not get great fitting parts - But save thousands as well!

Soooo aggressive June 22, 2017

I upgraded from the Performance style diffuser to this one and damn what a difference. This diffuser is a lot of money, but compared to the original it is not bad and the quality is on par with the PSM pieces. Now I get compliments every time I go to the gas station.
