Just bought a duraflex Vader 3 spoiler for my 2006 Z.

anyone installed one of these? No instructions included so wondering if 2 way tape would work(3M).

any online links available?

 

That wing is too big for double-sided tape alone. I would imagine something that large will need to be attached with screws and/or some type of strong panel bonding adhesive. Best bet would be to take it to a body shop.
