Using these OLM STI V2 Paint - Matched Spoiler Side Fins is a breeze. First, clean the surface of your wing thoroughly. Then, take the provided double - sided adhesive and stick the side fins to the wing. You can also use the supplied hardware to mount them for added security. When applying the adhesive, make sure the temperature is between 70°F to 100°F (21°C to 38°C) for the best results. After installation, give it some time for the adhesive to fully bond. At room temperature, it takes about 72 hours for the full bond strength. Avoid driving at high speeds right after installation to let the adhesive set. For maintenance, just clean the side fins regularly with a mild car cleaner. Check the adhesive and mounting hardware from time to time to make sure they are in good condition.
