Hi, first time to use the forum. Many thanks for all the helpful tips, especially the one on disabling the stop Start function!

Does anybody knows how to make the rear wing stay up all the time. I prefer the look of the wing up than down. I know it raises at 70 mph automatically and you can also raise it when the engine is off by pressing the starter button and then the wing button (good when washing the car).

 

would raising it up and manually disconnecting the power work?

 

Yep, that might work.
Wilgur, have a read through this thread: https://www.jaguarforums.com/forum/f...+rear+spoiler+
I don't know if the SVR spoiler works the same as the "normal" spoiler, but if it does then simply raising the spoiler then removing the cover (11 Torx Security TS27 screws) then disconnecting the white/grey electrical plug underneath then re-fitting the cover should do the trick.

 

Put in cleaning mode. Disconnect wiring harness

 

Is removing the SVR carbon wing a big job?
I am considering removing it for my next attendance at the drag strip to see if it actually makes any difference.

Putting it in the lower position seemed to have no effect, but I suspect it really only comes into effect when trying to push to around 200mph, as I know it does not generate much downforce.

 

Probably a fairly simple job to remove, see post #133 in the thread I linked to above, here: https://www.jaguarforums.com/forum/f...7/#post1614196
I bet the four mounting bolts that hold the spoiler lid on for the "normal" spoiler instead hold the "feet" of the SVR wing, so just remove those bolts and the wing should come off.
Of course you will have four ugly holes in the lid left behind, maybe just plug them with suitably sized rubber grommets?

Edit - here is the parts diagram for the SVR wing, hard to tell if my idea will work or not: https://www.jaguarlandroverrenoparts...t/spoiler-scat
It looks like the "feet" are integrated into the "spoiler lid" so will be left behind with holes in them.

 

Thank you, I see that thread goes into detail about removing wiring / motor possibly.

As my car is an SVR the spoiler is always up anyway, its lowering it that requires a button press and if you do lower it well it will always raise itself again at a certain speed unless the car is in vmax mode, otherwise the default is always up.

Shall probably pull it apart to see what is in there, but for drag strip testing I suspect like you say undoing the 4 torx under the SVR wing will then allow it to be lifted off and removed which will be enough for testing to see if the wing is causing any drag even at quarter mile speeds.

 

Now that you received some rational answers......Little blue pill might work, but side effects could be troublesome.
