I'm converting my exterior from an S4 to an S5. Bumpers and side moldings. My question is, how many peices are there to the S5 moldings? I don't want to get jipped!

 

The trim is made to the bumpers and if you get the S5 side skirts then its made to them also. That would mean

2 on the front fenders where the signals are
2 on the back fenders where the signals are
2 door strips

If you don't have the side skirts then add another 2 pieces on each side where the fenders are.

 

I also want to do this, but do the lights from the S4 moldings fit right into the S5 moldings or do the S5 molding lights have to be purchased as well?

 

The lights will fit. Just not the front turn signals.
