PP springs vs Eibach Pro-kit

[Giaco]

Hello guys I have a big question: are the Eibach Pro-kit prings the same as the 2015-17 GT Performance pack?? I found one of these kit and I mounted it on mine and the car appears exactly the same. Thanks to everyone.

But in 2015-17 there was only one pp, wasn't it?
I bought some spring from a guy. I supposed they was the Eibach pro-kit because they were in a Eibach box, they were black and he said he took them from Ford. When I mounted it I found the car exactly the same. I compared the two (you too can see those circled in photos with are in the same position): the front spring (red circle) were exactly the same but the rear ones (green circle) were different, in fact the new ones were longer but with less "circles".
I ask him and he said that these were the pp2 springs. But for 2015-17 there was not a pp2
So now I'm confused.. wtf I have mounted on?

Have you compared part numbers that are on those paper tags ?

Yes. It looks like your new springs have them too, if it says FoMoCo on them they're most certainly not Eibach, JR3C-5560-HA is the actual part number.

That was the one of the new springs. And my old ones have a similar one (RRH fr3c-5560-ha).
I realized that is not the Eibach pro kit, but what kind of springs are them?
I'm from Italy and I try to search something on internet but I couldn't find anything :(

I wonder if someone bought Eibach springs, put them on their PP car (or had Ford put them on) and put the PP springs back in the Eibach box.

Eibach springs should have the Eibach logo on them. Yours don’t.
I bet you now have 2 sets of the same factory Ford springs.

Eibach Pro kit are black but they will have the Eibach logo and part #'s on them they do not have tags on them like factory springs do. they are also a higher spring rate then the PP1 springs and do sit lower then the PP1 springs. one of my sales guy's has them on his 2017 GT.

But from what I see you have a 2015 Gt (like mine) and from another post I read it's auto. So when you say that you have just took off the pp1 springs you mean that you put them on before, because them are not the original springs of your car. In 2015-17 there where not a pp1, just the pp, and wasn't available for auto transmission.
That code of your springs is effectually the same code of the unknown springs that I have bought.
So if that is the case I have change mine 2015-17 PP springs (fr3c-5560-ha) for the 2018+ PP1 springs (jr3c-5560-ha). So it's an upgrade, I hope..
