My 2017 GS has the Stage 1 rear spoiler, I'd like to upgrade to the Stage 2. Any benefits / detractors here? I'd also be interested in the numbers as far as down force / drag change. Thanks!
Going from Stage 1 to 2 will create 400% more downforce. This was mentioned by Tadge a while back. Negatives? A presume about mile, or less, in fuel economy, slower top end, and reduced visibility.
I went from a Stage 1 to 3 and noticed no difference in drivability, just a slight reduction in rearview mirror visibility, which I got use to and don't find it to be an issue.
Although functional, for most people the add-ons are just for looks.
Like, I am sure the side skirts also have a function (besides blocking rock chips) but I don't like the way they look, so I will never add them to my car.
I did add the z51 spoiler and stage 1 splitter since I don't particularly care for the huge rear spoiler look.

I freely admit it's for looks. Yet go look at yours imagine about 1" taller spoiler. I think it'd off set the "stubbylook" of the tailend of the car. Mine just kinda disappears in the silhouette.
