I have search, i didnt get any answer, i think the search button is not currently working. But anyways i kno there was a thread n a mentioning of a S4 to S5 conversion. I remember something about the molding is basically the same thing but painted but u can fit a S5 molding but need some epoxy to get it to stay, etc.
I dont remember do a S5 bumber fit into an S4, and is there any cutting or wiring difference for the turn signal.

- i dont remember bcuz i had a concussion juss a few days ago, because i ran into a gate, and my mom is calling a retard fot it.

 

yea the bumpers fir just fine, you may need to remove or trim the brake ducts...the molding is slightly different tho, also the turn signals are different, but the s5 signals will plug into the 4 harness.

 

I know the rear bumper is a perfect fit, the side molding on S5 are clip in, the S4 molding is double sided taped or glued on i believe. The side marker lights are the same, you can just reuse the S4 markers. Not sure about the front bumper.

 

0, alrite thanks

 

Next time please read the FAQ for FC sticky thread found at the top of this section. It covers many of the commonly asked questions such as the majority of the ones that this thread was started with.

And you will need to get S5 turn signals, as the S4 ones are a different size and shape.
