The DF-R Side Splitters is a simplified design that will give the Scion FR-S / Subaru BRZ that aggressive lower and wider stance. The splitter is made with Hexcel carbon fiber or FRP. DF products comes with an UV inhibiting gelcoat that will protect the carbon from sun exposure.
Simple straight forward installation will require you to drill a few holes. The part is molded to follow the contour of the Scion FR-S / Subaru BRZ chassis so there is no guess where to mount.
