Hey everyone I'm going to be getting some s5 tail lights and was wondering if they will directly swap to my s4.

 

they wil def. go on but i think some minor trimming of tabs is needed?

 

Cut the 2 cars in half and weld the *** of the s5 car to the s4 car..done!..(redneck style Billy-Bob!)..don't forget to hook up the wiring though..lol!

OR,cuts small piece of metal where the inner light(closest to plate) sits...
Really,if you take the S4 tail-light off and place the s5 tail up against the car you will see it easily.It's cake.
PS: seriously make sure that If you have a Coupe,then get COUPE tails for a COUPE..Vert tails are different.

 

This is a commonly covered topic, and it's even in the FAQ. Yes, there is a little modification required, but electrically they're the same.

 

Requires a hammer. Seriously. (or trimming)

I DO like Styx idea, though.

 

It will almost fit right in. No serious work needed. Just gotta Push back the metal back about an inch so the s5 backing fits. Didnt take any Special tools. just some bending was all

 

Awsome thanks guys for all the info, helps out a lot making my decision.
