I wanted to put the new special edition type spoilers on my 2003 A4, I find these on ebay and wonder if they would work, or is there a better place to get them from.

I'm a little worried about just securing it with teh 3M adhesive, let me knwo guys thanks!

They seem to have good e-bay feedback. As for the 3m tape. It won't fall off. Just prep the surface first and make sure there is no wax on the paint where the tape will go. Most urethane body kits are held on with the 3m tape and I know a carbon fiber maker that uses this thin tape all the time for exterior parts and never has problems.
