i did this on a clean, dustfree car;-)

remove the factory spoiler:

remove the cover inside from the decklid and the 2 plugs that cover the nut. the plugs will be reused! don't trow it away
carefully remove the 4 nuts.


P1010819_zpsf5d6b2e5.jpg

cover the spoiler and the decklid with the painter-tape and some blankets.

P1010822_zps2e984e09.jpg

use a 15 inch long piece from the nylonthread and begin on a side carefully to go between the decklid and the spoiler. pull up slightly on the same end on the spoiler helps to do this.


if you have the thread between make sawing motions until reaching of the first pin.(run the thread slightly towards spoiler and not to the decklid!!!) slightly pull up the spoiler everytime. use one of the nylon trim tools.
cut as much as possible around the pin and push through the thread after the pin. use the nylon trim tools to pull up the spoiler everytime.

once more: take your time to do this!!!!

punch all 4 locations and drill the holes with the 3mm drill. drill the holes through both layers of sheet metal (outer and inner) in one step.
(use a vacuum cleaner or masking tape to catch the drill chips)

to this time i had not the spoiler back from the paintshop and i could not make sure that the holes fit to the new spoiler. if you have the spoiler at this time put it together and make sure that the holes fits with the screws.

now you can paint the edges on the holes with the touch up paint or with primer. let it dry out long enough before you install the new spoiler.

P1010853_zps5007842d.jpg

install the new spoiler:

put the new spoiler together. use degreaser on all surfaces on which an other part with tape attached. heat up a bit the 3m double site tape before you stick together the parts.

P1010858_zpsb8549ef0.jpg

if you have the spoiler put together and the 8 holes fits with the screws you are ready to mount it :)

i used a strong tape to cover the big hole from inside the decklid. then i used a small amount of the rtv from outside the decklid to make sure that the hole is fully sealed waterproof.

P1010878_zps5413c1b8.jpg

P1010877_zps100e5e7c.jpg

carefully put the new spoiler on the decklid. if you someone can help you on this step; use the help!
carefully install the 8 new nuts. tighten from the center towards outside.

on your deck lid, whats the large hole for. I dont remember that when I did my spoiler. But that was 3 years ago.


on the boss's is this hole useless, but i think this is the hole where the cable goes through if the mustang is equipped with a rear view camera
 
Andreas, great job on documenting the install. This should have been an option from the factory.

Great job on the write-up!

You are correct! I've seen the connections on friend's cars with the camera option.

1+ also the wheels.

+100

I wish the pedestal spoiler was an option, but I'm guessing it was a "marketing decision" to have the pedestal spoiler be an LS thing, along with the wheels.

Great job on the instructions.

I totally understand people's desire to mod their cars, and someday I hope to find a less-than-pristine Boss that I can afford and mod to my heart's content. I love the way the spoiler looks, but I'd never cut into my car to install anything, and I admire those who can do that kind of stuff without flinching. I plan on keeping the Boss at least until I can get my money back out of it, which will probably be 30 years or more. I saw too many classic muscle cars of my youth modified in ways that really reduced their value and that keeps me from doing anything to the car that can't be undone, but more power to those who can do tasteful mods like this one.
 
buland thank you for that great walk through.

Did you notice any balance changes due to increased downforce? i'm looking to add rear downforce over the GT mini spoiler but not a huge wing since that's not street.

Is this the most functional spoiler out there for our cars or did you simply like the way it looked?

I asked a Ford engineer about the differences while attending a CTSCC race and if I recall correctly the difference in downforce between the LS and Steeda wings were very similar. The one advantage was the winglets on the Steeda are supposed to provide a bit more stability during high speed braking but most likely only a professional can notice the difference. The advantage of the LS wing is it uses all the stock holes, plus you have to drill four more, so you don't have to fill holes not used with the Steeda wing. Additionally the LS wing has slightly more downforce than a GT500 spoiler but again only a pro would notice. It's advantage is it's a straight bolt on.

The LS wing and front valance on the 2012's were designed for the Boss program from the beginning and were used on the CS to help spread the development costs.

Thank you for your words. Because the Snow i could not do a Testdrive. But @NFSBOSS is right.
For me is this mod only because the better look.


Today i got a invitation for a Testdrive in April on the Monza Racetrack in Italy. Perhaps i notice some difference ;D ;D ;D

Buland, excellent walk thru and photos. I plan to add the LS spoiler to my GT one day. Thank you.

For those of you that have replaced the stock spoiler with the LS version, what paint did you use on it? I want to shoot with something that is very durable and close to the color and texture of the stock wing.

You're up early!

Any paint shop should be able to use the factory paint code and match the colors precisely. Those codes are on the site somewhere, probably in the registry forum.


you're right. i put on the green t-shirt and attend today a drift-training with the boss.
