Thats why I had mine installed at the delivery center. Read too many stories about bad installs and these possible issues with a DIY install with tape. BTW, the performance spoiler is nothing like a lip spoiler, it is a lot bigger and could put a lot of torque on the attachment point. Driving won't cause any issues, even at speed, grabbing the spoiler to close the trunk will! Not that I every do it, but others touch it.
