Is there a fuse I can pull or wire I can unplug to keep the rear spoiler from going up at 75.

Mine works fine I would just like to disable until I really need it.

 

You could pull the relays under the back drivers side seat or unplug the 2 leads to the hydraulic motor by the fan. The fuse is for the hydraulics and back lid latch, so that's not an option.
Just be warned, as stated in your manual, Porsche wants the wing up above 75 mph for added rear downforce. Probably to prevent twitchy oversteer.

 

i'd say leave it, and do not play with it, mine is always in down " position " , took the motor out and i love the sleeper look

 

Do you know the exact location of that relay, will that also keep any lights from popping up on the dash?
I just want to disable for when I go drag racing or not so aggressive casual driving. I figure less wear and tear on it will prolong its life......
I actually prefer it in the down position but know why its there are would like to be able to re-enable it when I need..

Thanks

 

If you want the rear down and no lights you need to disconnect the plug in the engine compartment and buy a GT2 loom that plugs in and then you will have no lights. BTW ive had mine over 180mph spoiler down and TBH didnt notice any difference.

 

id like to see the wind tunnel tests on that little baby wing and see how much downforce it actually creates

 

I've seen the info, but cannot remember exactly, it's something around 30 kg IIRC. The aero balance front and rear is fairly critical on these cars, as many have attested to in prior threads.

This is based on anecdotal evidence, but it seems to me that the hydraulic wing issues effect cars that sit more than those that are being driven. The seals live a longer life when used.

 

9kg (19.8lbs) of down force is created by the rear wing at a top speed of 190mph. At 75mph, you are looking at about 8lbs of downforce at best. It's a joke...

 

i agree, without having any specifics. but at 75 mph it HAS to be a joke, "gimmicky" thing that it is.

at 175+ i'm not so sure it was intended merely as "plumage", though tooling around from onramp to offramp, it clearly is. "plumage", that is lol

 

While the downforce is not as serious as some guys make it out to be, it's not entirely a joke either.

Almost all normal cars without aero make some sort of lift at speed.

I wouldn't focus so much on net downforce, which is minimal. Rather, how much lift it reduces, which can be significant.

I will agree for street driving, it's all moot.

 

i agree with everything you've said, but for the purposes of a discussion of downforce vs reduced lift, aren't they essentially one and the same thing, other than semantically??

or am i missing something? as the way i see it, "downforce" by its very definition "reduces" lift (!?)

 

Spot on. I think for track driving, it becomes pretty important. High speed on-ramp work - same. But in reality it was a necessity for autobahn driving at higher speeds.

 

maybe defined as downforce being exerted at all speeds and lift may only occur at certain speeds? the use of a gt2 rear wing has seen increased downforce but without the proper front bumper can actually increase lift in the front at high speeds. so downforce may not by definition reduce lift but actually increase it at a different place on the car

 

Not really dude, there are spoilers and wings, a big wing (F&F style) will create massive downforce but maybe knock 10-15mph off potential top speed whereas our 'spoilers' just pretty much interrupt the airflow over the back that is trying to lift the rear of the car up and introduces a small amount of down-force in the process. the difference in performance up or down as opposed to removed would be interesting to know, Ill wager no more than 1 or 2 KG !!
