Automatic rear spoiler question

[Guvs]

I have a dash board switch that lets me know when it's going up flashing Red LED at 75 MPH (in my Boxster) solid Red LED
when up, and it will only come down (flashing Red LED) when doing 50 MPH, unless I press my other retracting button at 60 MPH



although I think the spoiler on the Boxster is fantastic looking bit of kit , it does get a bit embarrassing if after you have put
your foot down to say join a motorway from a slip road and the spoiler comes up, you then slow down to 60MPH and your
spoiler is still stuck up in the "go faster mode" until your speed comes down to 50MPH when it will retract automatically,
you get what we call over here in the UK "Boy racers" seeing this (Spoiler up) as an invitation to a race against them in their
Vauxhall corsa's, so that is why I've put this button in to retract it at 60 MPH one touch manually works a treat.

I know that's the correct up & down speeds but is that switch oem option?
