does anyone know how to disable the wing from comming up at 70 mph

You need a PWIS to code it out.

there is also a way to increase the speed in which it deploys so the button still works to service the car. Just raise it to like 200MPH and it should never deploy

Having driven a 911 with a broken spoiler, you don’t want to do this. It gets squirrelly and needs the aero.

If you’re putting a fixed wing in place, sure, but that deployable spoiler is there for a reason.

Mine is going in for an adjustment next week, as it was loose and scraping the paint on the way down. I pulled the fuse which disables it, but the aero impact above 75-80 is noticeable.

i understand your point about the deployed wing being ugly from the other thread and it always bugged me too

At what speed?

You start feeling at regular highway speeds. The car doesn't feel quite planted. Anything north of 70MPH and it becomes a white knuckle proposition. The spoiler serves a critical aerodynamic purpose -- it reduces lift that is generated by the 911 shape profile.

If the disabling of the spoiler isn’t because another fixed GT wing is being installed then don’t do it.

If its for the esthetic than do your homework. It's not just for show. I assumed the OP was installing a big GT wing for a track day.

I am not trying to be argumentative just trying to learn something here. do you have data to support this. The 911 has been the same basic shape forever and the instability was solved by improved suspensions, wider rear tires, moving the engine foward and electronic stability control. I just dont think it makes that much difference at Normal driving speed. Personally if I had access to disable it I would.

[QUOTE=raaizin;18825107]Your not considering aerodynamic lift.

If you haven’t studied fluid dynamics or aerodynamics it wont be intuitive.

[QUOTE=raaizin;18825107]I've driven a 911 where the spoiler was broken and wouldn't deploy. I can't recommend the experience. It's vital to the aerodynamics of the car. None of the things that you mention matter if the car is generating lift.

Over the years, I have learned to take aero modifications pretty seriously. I've learned that if you put a big wing at the back of a car, you better be putting a larger splitter up front. I don't half-*** aero.

As someone who has driven without his spoiler for 3w (bolt loose, goes in this week for a fix), I can attest to this. I pulled the fuse bc it was scraping the paint on the way down and above 70 the car feels unstable (dry conditions with brand new ps4s too). I haven’t exceeded 80 without it but can imagine it getting very shaky.
