I just received a B6 lip spoiler for my 03' A4 1.8T. I actually thought it was supposed to be in the form of firm plastic but it seems like it is able to bend and itt has the self-adhesive on the bottom of the lip. When I tried fitting it on my trunk, it looks like -- without bending -- the spoiler extends to the taillights on both sides. Am I supposed to bend it slightly while installing it so it covers only the trunk? What are some good tips to position it right?

 

You need to bend it to match the curvature of your trunk, it should line up near perfectly with edges, maybe a small gap on each side. It takes a little time to get it perfect but once do you will like the look. To answer your questiom, no it should not go over the tails at all.
