That being said, I have seen several posters on here who swear by the tape, and also several that have had their spoiler fly off on the freeway. I have never seen anybody lose a spoiler when using Bettalink. Mine has been on my car for 2 years and is still strong as ever. The car has even been through high pressure washes with no problem.
I chose to paint just the top of my spoiler so that it flows with the car more and doesnt look like something I just slapped on. To each its own though. I like that you can still see the CF from the back.
Wow! Up I-70, that must tighten your sphincter?!
Just remember OP if you use betalink when you remove that spoiler at end of lease you will likely have paint damage to repair before replacing OEM spoiler. If you're good with that I'd say leave the Performance spoiler unpainted and slap it on! I will probably put one on soon.
