LOL, yep. My original thread was just asking if anyone had the brace, and it turned into something totally different. Guess thats how forums work though, hehe

***See post 36 below, this issue has been resolved*** An update for those wanted to install the Granatelli Single STB on 2007's. I just got my 2007 GT Premium Vert in on the night of 2 Aug, and on the morning of 3 Aug my Granatelli Single STB arrived. I eagerly attempted to installed it, and quickly determined that contray to popular belief, there ARE changes to the 2007. The Single STB that DID fit over the Ford Engine Covers that are being retrofitted to 2005-2006's, will NOT fit over the Ford Engine Cover on the 2007. It wasn't even close to clearing the cover, and the mounting plates were not even touching the strut towers it was so high centered on the cover. I will be returning the STB as it won't work, but the folks at Granatelli were very helpful and understanding. Not sure what changes Ford made to the Strut Towers, or if the engine now sits higher, but they did change something.

I heard the '07 strut towers were altered to fit the 5.4 in the engine bay. That may be it.

I got my Granatelli double street brace today. I week ground shipping coast to coast. I love the look. I love the design. Just what I wanted.
Type Bar-- Granatelli double street
Type hood ----Stock
Plenum cover--- No
Clears hood mat--- No, the back bar holds up the cover so the front doesn't touch. Just rubs a little though... good enough for me.
Just for the record I saw an '07 GT appearance package today. The Ford plenum cover rubbed on the hood mat in the back, you could see the indent.

The 07's are more different than we think. Hatchman and I tried to put his Strange Development STB from his 05 on my 07 today. It was not even close to fitting the 07. It looks like the 07 strut towers are slightly shorter, and have a different angle on the top.

Yep, 05 and 07 strut towers are different. We couldn't even get the Strange STB down over the strut bolts, the brace was about 1/4" too long and not angled enough.

Pics to come.

The strut towers on the 07 were supposedly moved a little apart (or at least reshaped) and beefed up to accomodate the Shelby GT500's 5.4 liter engine. There were also other parts of the 07's chasis that had to be stiffened for the Shelby, so all 07's benefit from these enhancements.

Does that make the '07's heavier too, like the bloated GT500s??

Below are pics of the Granatelli Single STB not fitting (it is the black one) and also the Strange Development STB not fitting (it is the polished one). Also notice the difference in the strut towers themselves, mine are the 2007 Satin Silver Metallic, and the 2005's are Hatchman's Mineral Gray.

Granatelli Single Street, OEM Ford Cover -- Bar fits over the cover, rubs the hood mat slightly. Overall, great combination.

Type Bar: Strange
Type hood:Stock
Fits over Plenum cover?
- Ford - Y
Clears hood mat? N - Slight rubbing
Any other mod to fit right? Took rubber grommets out of side of plenum cover and put them over top of the bolts to suck the plenum cover down to provide more clearance otherwise there would likely be plenum/bar rub at full engine torque.

Disappearing posts, this thread

My earlier post to this thread is also missing. Oddly enough, when I search for all posts made by me, this thread still gets listed.

Great idea with the grommets. What do you consider slight rubing on the mat? I guess there is no do all solution for STBs, Plenum covers and no rubs.....

An update to my update. Jim at Granatelli experimented with the Single STB on a 2007 with the Ford Engine Cover this weekend. He called me today with the solution to make it work. The stud and nut combo they used to hold down the fuel rails on the 2007's make the cover sit about 1/2" higher than on previous years. The simple solution is to just temporarily take out the stud and nut combo, THEN mount the Ford Engine Cover, and then reinstall the stud nut combo on top of the engine cover mounting tabs. This lets the cover sit down further a good half inch, and provides plenty of clearance for the Granatelli Single STB to fit over the Ford Engine Cover. I am a happy camper with my STB! This solution will probably also work for others with the Strange Devlopment STB which Hatchman and I also tried with no luck previously. In short, now the Granatelli Single STB DOES fit 2007's with the Ford Engine Cover as long as the above mentioned steps are taken.

My car is wearing the Strut Tower Brace mentioned in the previous post.....it is an easy, easy fix. In essense, Ford puts the cover over the nuts, rather than under them....because it is an "add-on" piece and they don't want to take the time to do an extre step. Also, no difference in the shock tower struts over an '06.

The fit is tight, no doubt, but very acceptable. Keep in mind, these covers heat up and expand. When I got home from GMS it was nearly touching...and so what if it were to9It hasn't)...we are talking a piece of molded plastic! Also, as best I can tell it does not touch the hood pad.

Also of interest, the engines on these cars barely move under acceleration..maybe 1/8 of an inch. This is not your 60's muscle car.

As far as performance, there is an incredible improvement in body stiffness....especially when paired with the A-arm brace which bolts under the car side to side...not sure why anyone would get one without the other...its a great set-up.

Bill, Thanks for the info. Did you get the A-arm brace from Grantatelli as well? I have to disagree with your last sentence of your first paragraph however, because there are differences to the strut towers. Look closely at the last two pics of my post #29 above and you can clearly see they are different from 2005 to 2007. Good to know that it doesn't affect the fit of the Granatelli brace however.

Yes---Mustang Brace is from GMS......re: the strut towers....there may be some visual and even design changes but as far as basic dimension I believe they are the same

Yeah the grommet trick worked like gangbusters! As far as rub from the bar on the mat, you can see on the high point a slight and I mean really slight dent in the hood mat and it's a slight shade of grey different from the wear. It doesn't look like it's getting any worse than it was after the first little while with the bar.
