I just received the new lowering springs for my year old 2013. My Christmas present to myself. (My wife gifts herself to new clothes, so I'm happy)
Well, as we were taking the new springs out of the car she said "Why don't you trade in the 2013 and get one of those new 2015's since they look so great - just with an automatic rather than the stick you now have."
Shock! and wonderment. She is about due for a new car too, so maybe she is just priming the pump.
Now I have questions. Should I save the springs for the new car? Is the new new 2015 the same platform as the 2013? Anyone know about compatibility? Such a tough new decision to have to make

Can't speak to your situation, but the lowering springs on my 07 GT are coming off when I get a round tuit. Ride is terrible, even with new Koni shocks. Car cannot go straight down the road, and follows every rut, so I do not understand how they call them performance springs, unless they mean LOW performance. Everything about the cars ride and handling characteristics is flawed on anything other than a perfectly smooth road. Corners are fun but, unfortunately, 99% of the drive is in a straight line. If not paying attention on some roads, I could see how one would lose control of the car. It is no wonder the TEN O'CLOCK news, whenever a fatality accident is shown where some teenager killed himself and a friend or two, usually shows the mangled carcass of a late model Mustang.
Hard to believe, but my 66 handles and rides better than the 07 GT convertible now.
I sure hope Ford gets the 2015 sitting down lower with a suspension that is designed for that ride height so we don't have to ruin the ride and handling to get a cool look.

I'm on my third set of springs on my wifes 05.
With the o/e set of coils the car sat as if Ford wanted them to be used with tire chains.
The second set,Eibach, the car was so low I could drive over a nickle and tell if it was heads or tails and the ride was so rough that a trip to the dentist was needed to replace fillings.
The last set is from Ford and included the front struts and rear shocks.Tthe ride and the ride height are now as it should have been from day one.
As for saving the springs you have, the new S550 is a couple of hundred pounds lighter than the previous year so I think that even if they did fit the ride would not be compliant.

155 MPH top speed
Even more detailed changes:
New cams with 1mm more intake lift and 2mm more lift on the exhaust side
New cylinder heads with revised high-flow ports and slightly larger valves
Mid-lock cam phasers to provide greater range of cam timing on the intake side
A revised intake manifold with charge-motion control valves.
The forged connecting rods from the current Boss 302 engine

3.7L V6
300 HP
270 Lb-Ft
2.L inline 4 Cylinder EcoBoost

revised shift linkage for shorter throws / smooth shifting
Automatic with paddle shifters (SelectShift 6-speed)

Suspension
All-new front and rear suspension systems.
New perimeter front subframe helps stiffen the structure while reducing mass, providing a better foundation for more predictable wheel control that benefits handling, steering and ride
Front MacPherson strut system with new double-ball-joint spindle (allows for larger brakes and improved handling feedback)
Rear integral-link independent rear suspension (benchmarked against Boss 302)
New aluminum rear knuckles help reduce unsprung mass for improved ride and handling
Brakes
Three available brake packages
V6 Mustangs: 2 piston calipers with 12-inch rotors
Ecoboost 4 Cyl Mustangs: 4 piston calipers with 14-inch rotors (standard on GT model)
GT Mustangs: 6 piston calipers with 15-inch rotors (upsized 15% from GT500)

The 2015 appears to be everything one could want in a car. Hope they get the ride height correct.
Rudi, which Ford springs did you buy? My Eibachs have to go.
Also, it seems I read somewhere that Ford has a rule that any of their vehicles have to be capable of handling tire chains. Fact or fiction?

The ones I bought are SR's. Anyone know anything about them? I got them on sale for $100, and maybe that will be a lesson well learned if the only responses I have are negative. No point in installing them if I am going to revert soon afterwards. Maybe I'll put them out on Ebay.

I tried some google searches on SR springs - most seemed to like them compared to Eibach. But, I also found a thread regarding the installation on 2011 and newer cars - apparently from the American Muscle web site - They will also fit 2011 and newer GT & V6 Coupes when used in combination with Ford Racing M-18183-C upper strut mounts and M-18000-A dampers (sold separately).
Apparently, in the link the strut mounts are weak and/or fall apart when taking it apart to install the springs and as you will read people suggest the GT500 upper strut mount. There are several utube videos showing the "after" from an install and they do indeed improve the appearance. Looks like you will be into $100 more for the strut mounts if you decide to go ahead but perhaps others have experience on the 2011 cars - but since this was posted on the internet it has to be true.

The 2015 is lower than any other mustang

Steve, I got the Ford handling package kit from CDC but they are sold out.
One of their dealers, Blow By Racing in Florida still has a couple in stock though. The Ford stock numbers were blacked out so I can't help you there but if you ask for the set that CDC was selling they can give you more info on them. Blow By should be able to tell you more about what the kit consists of and their application.

You need to insstall the new GT500 strut mounts anyway if your car has alot of miles. I did, but they were same part number as originals on my 07. It did get the CLUNK out, though. You can turn the mounts 180 degrees and get more camber, I figured out. Never heard that mentioned before.

I'm a little worried. I got the springs on a deal from American Muscle $100. I looked up the M-18183-C Strut mounts($160) and the M-18000-A dampners ($670). I bought the car with the sport suspension (all kinds of heavy duty suspension stuff). Do i need to spend all that extra money just to get the car lowered? I can handle the strut mounts, but the struts are only a year old and stiffer than stock. Can I get by without them?
I would like to eliminate the need for the new mounts too, if possible. How do I find out what I can get by without?

When I did mine, I could see no difference whatsoever between the GT500 strut mounts and the original 2007 GT strut mounts, even same part number. The mounts on the newer Mustangs is a little lower at the top so maybe the earlier springs would change ride height? Don't know all the details, but I know the 2010 and newer are a bit different in the height the strut fits it.
Also, Amer Muscle sells the FORD JOUNCE CUSHIONS as something special and they were the exact same things that came on my GT.
