I dropped my car off tonight for my Veilside version 2 wing to be installed and installer has me worried. He said he didn't think those 2 screws would hold the the spoiler on tight that it would rattle and move around a lot. Should there be 3M tape or some other dual sided sticky tape installed along with the 2 screws or will the 2 screws be enough to hold it? Please help, he has me extremely worried now.

 

Yes use 3m tape the screwsalone will not hold the wing.

Your body shop should know enough to do this.

 

Just an update the body shop used urethane he said 3m didn't appear to be strong enough, anyway visit this link for some pics

use exterior doubeside taped. Holds up to 5pounds per inch.
