This street-version splitter is a high quality carbon fiber aero component for your 818S or 818R, sandwich molded by our skilled craftsmen. The top surface is finished in a clear gel-coat and requires wet sanding & clear coating for a 100 point show finish.
**IMPORTANT INSTALLATION NOTE**
Based on wind tunnel testing, this street-version splitter produces a significant amount of additional downforce at speed, and in order to achieve a safe and effective balance, we highly recommend using it in conjunction with our #80819 Carbon Fibert Spoiler. If the street-version splitter is used with no additional rear downforce, your car may exhibit a significant oversteer tendency at higher speeds.
Please note, while a rear diffuser does also create rear downforce, its effect is more even along the length of the car and does not sufficiently balance the street-version splitter.
