I was trying to fit this to my Subaru BRZ with MY17 fenders. It's the perfect size and adds some bulk to the spoiler, but the double sided tape didn't hold. It will rise quickly and will not stay in place. I'm not sure if the pre-applied double sided tape wasn't strong enough or if my wing's coating isn't ideal for this application. Anyway, I can't risk it as it can fly away at high speed. It might have worked if heavier tape or glue had been applied, but I can't justify the cost. Other than that I think it's a good quality rubber but the grip wasn't the best.
