I went with the GM front splitter ordered with the car and EOS Sideskirt off of Amazon... the side skirt I painted satin black with Rustoleum Spray paint and installed myself with stainless steel screws and washers. I used black silicone sealant to close a small gap between the body and the sideskirts towards the rear of the sideskirt. Turned out very nice. The EOS sideskirts were 1/4 the price of the installed GM ones from the factory, no difference in the final look.
