2017 SG RS1
You know it! And don't forget the smoked indicators! Easily adds another 5 HP. Now that I think about it though, I should've taken a pic of the US ones folded in to compare to these Euro ones folded in. I'm pretty sure these ones fold in more than the US ones. Probably why the base is angled and the shape is different, as the mirror housing curves towards the bottom inside of the mirror (vs the straight down design on the inside of the US version).Great add-on this thread and the pics as stellar.
So the smaller side mirrors also help on less wind drag, hence more HP!
