991.2 Turbo
 

I have a 2019 991.2 Turbo. When I exceed 75 mph I can't tell if the rear spoiler deploys. Is this because it extends but not fully enough to see from the driver's seat? If so, does the deployment height differ in Sport or Sport Plus mode?

I can see mine up or down while driving from the drivers seat without any problem, you can also manually control it up or down so you can see it in both up or down position :)

I have a 2017 991.2 TTS. There are 2 deployment levels for my spoiler. The level is more dependent on speed...than anything else. Having said that, if your sunroof open or tilted, the second more aggressive setting does not engage. There may be other logic programed into the car that effects the deployment. I believe you can only manually deploy the spoiler to the first level.

It was hard for me to see the first level , but you will definitely see spoiler in the rear window if the more aggressive level is engaged. I have to admit the logic is still a bit of a mystery for me.

One trick is to put a piece of painter tape on the spoiler and partially rip it...then get on the freeway and let her rip. Good luck.

I can definitely see it when the top is down but with the top up I can't see it at all. It goes up around 75 mph.
