I apologize for my lack of knowledge, however I am trying to educate myself on what rear spoiler is on my car and cant find the information I need. I am the second owner for my car so I dont have the window sticker. I do have a copy of the build sheet though. My goal is to put the spoiler that is a little taller than the one I have. My car is a '18 Grand Sport with the Aero that comes standard.
So, what do I have, and what do I "need"?
I am wanting this for aesthetics only. I'm not a racer.
Grand Sports come standard with the "Z06" rear spoiler, along with "Stage 1" aero winglets which are bolted and 3M-taped on to the rear surface of the main spoiler body.
A common upgrade is to detach the standard "Stage 1" winglets from the spoiler base, and replace them with the "Stage 2" winglets (taller). Certainly not "needed" for any street car, so whether or not you like the look is totally up to you.
"Stage 3" rear spoiler is the same as Stage 2, except it adds an adjustable smoked/clear "wickerbill" section that bridges the center gap between the raised Stage 2 winglets. A "Stage 3" wickerbill can be added to any "Stage 2" spoiler without changing out the Stage 2 winglets, but you do need extended bolts to properly attach it.
You can easily tell the Stage 1 and 2 winglets apart by their heights -- the standard "Stage 1" rear spoiler winglets just barely rise above the body of the Z06 spoiler (about 1/4"), where the Stage 2 winglets extend approximately 2" (or so -- I don't have the true measurement handy) straight up from the top edge of the main rear spoiler body.
As others have said, you have the stage 1 aero package. You can add Stage 2 fairly easily yourself as all you need to do is order the Stage 2 winglets. They are an easy install and you can find them from popular forum vendors on here for relatively cheap ($300 or less).

Here is a link to one forum vendor as a source for the OEM Stage Two spoiler winglets. That's where I got mine...

The stage 2 wings can be found for $190 and up plus shipping from most GM parts houses. There is a GM part vendor in Oklahoma that was selling them for $149 plus $7 shipping. I bought 2 sets from them for both of my Grand Sports. Every time one of these spoiler threads came up I would post their link. I probably sent dozens of buyers their way, so many that they decided to raise their price.
You can sell your stage 1 wings here in the for sale forum. I've sold 2 sets for around $75 ish, IIRC
