The GT/CS or Shelby GT owners downdraft mod. ($5)

[07ShelbyCS]

Hey everyone, got bored at the Lowe's today after looking through some 10+ mustang forums.... picked up two new items that I installed, I was actually suprised at the difference I noticed when I hit 120-135mph down in Mexico post-installation. I used to have a problem where it felt like my front end would start to float around 120, but now ive fixed it. Yes, they are adjustable, I had them 80% extended and it seemed to do the trick! more downforce FTW (may not look the best, but when the guy next to me decides to turn into a back-flipping airplane, ill be happy staying on the ground)

*the install:


1. remove bottom cover, as to expose the lip on the front fascia,
2. look under the lip of the fascia at the two push pins that hold the secondary bottom cover
3. insert drill into the two push pin holes and drill upwards through the lip
4. insert the eye hole screw in the gap between the top and bottom of the lip so the eye of the screw is not seen.
5. go up through the bottom gap and drill into the lip of the front bumper frame
6. line up the hole in the top screw with the hole just drilled
7. get a metal screw, with a washer and put the screw through the hole in the eye-screw and then into the frame hole
8. before you put on the large silver double female ended "bolt", go on the bottom eye screw, put two washers and a nut to tighten the screw into place.
9. tighten the large silver "bolt" to desired tensity to get the bend you want in the front lip





(difficult to describe in text, ill try and get more pics up when I have some time)


heres some pics,

How about some details of what and how about the install to make this a tech worthy thread.

 

[DRock]

I can't see those doing anything. If your front end is floating then it's probably suspension related

 

[michschi]

I see four worthless holes in your bumper now.

 

[Irishman]

I'm pretty sure your not going to lift the front end at the top speed your car has
There are people hitting your speed in less the ten seconds not flipping over from the wind haha. Doesn't look to bad but to say its doing much is iffy at best.

I have hit 135 in mine and it was rock solid. I does look interesting though...maybe locate them at the outer edges of the lower grill opening.

see, my mustang gets the crap driven out of it. its a flat out POS, this was more for fun, the car got appraised for $12k, so I decided to have some pointless fun. Through the fun, i just noticed that it feels like when you go fast, changing lanes (traffic) feels more solid, less of a floating feeling.

What it does, is it widens the opening, allows just a little more air into the front. Its basically a pointless mod, just about as pointless as the front splitter on the Trak Pack Roush and RTR's.

haha the install:

1. remove bottom cover, as to expose the lip on the front fascia,

yeah.... no. Ive redlined fifth gear, and your bumper is not the issue. Trust me. That feeling at those speeds is the loss of downforce, those aren't doing anything except making you slower for the weight.

Look ok i guess

 

[gil_t2]

IDK, but the float fealing could be from all the openings in the front, with the foglight openings, and what looks like brake duck openings. Just a though

You have no idea of high speeds / downforce do you?

 

[07ShelbyCS]

@SilentScope- downforce it is, ive got the GT500 rear spoiler which unfotunately doesn't provide that much downforce. With suspension, I'm going to lower it soon. Should make a difference.

As far as suspension goes, im running the Eibach adjustable sway bar up front, and the Anti-Roll kit in the back. I get the "lift" feeling more often when Im on the Street setting (middle hole) than opposed to the Track setting (forward hole), what I did wih these bars, when combined with the Track setting seemed to make somewhat of a difference, probably just by adding more wind resistance up front?

 

[SilentScope]

that gt500 spoiler is not a spoiler, its a lip. and thats for the rear.
The front downforce is created partly by underside vacuum and partly by splitting the air over the top. Basically, you want to shut that gap between the road and the front of your bumper to create the largest vacuum under the car.

All the other things being discussed here (those bumper tie-rods) have null effect.

You want a gt500 chin splitter, and to lower the car as much as you can to eliminate that floaty feeling. An underside body panel does magic. I have a cut sheet-plastic from my bumper all the way to the swaybar.

Finding a way to get air out of the engine bay is a good idea too. Our cars are especially notorius for building up air dams in the engine bay because the front end devours air. Massive radiator opening. Cowl hood/fender vents (yes, they work) will help that air pull out.

Think knife through butter

lol

aaaaaa no...
