maybe some sort of mylar liner between the two?

 

I think you guys are confusing S4s and S5s



DOES Anyone have pics of the Turbo II front lip? Is it different from the black rubber piece that is below the front bumper? My car has this and its the only one like it ive seen. It is a piece of ****. Looks like its about to fall off, and sags down on the sides right before the front wheel well. Of the few T2s I have seen, I have never seen the lip. I guess Im special

heres a pic of it:

 

Your lip is part of the series 4 aero kit. It came standard on the 86-87 Sport, 88 GTU, and 88 T2.

They don't droop if you haven't broken the tabs or hit the curb too many times bending the brackets.

The series 5 front spoiler/lip and side skirts are considerably different than the Aero kit parts like you have.
