OK, I've tried. I really, really have. I've done searches until blue in the face, and all I've ever found was a chart for earlier Mustang springs. Nothing on Google, nothing here or other Mustang Forums.

I have a 2007 Pony Package V-6. I'm autocrossing it. Given that I have to beat the Mini S's in G Stock, I'm looking into just changing it into a car that is what I want it to be, not what SCCA says it must be.

So anyway, I'm researching changing the springs. I already have the Steeda front adjustable sway bar.

I cannot find anywhere a listing for what spring rates come with the standard V-6, Pony V-6, standard GT, Bullitt, etc.

I may want to try the GT springs, or a Steeda set, or something else. Being of a fussy nature, I'd like to see the actual numbers to ponder my options..... Can anyone point me in the right direction?

Any and all help and opinions welcome, especially Sam S's.

Thanks,

There is a list in the front of the Ford 07" Mustang Workshop Manual.

You will have to ask the forum members for their model type
and the spring codes on the door jam info sticker to match
the available part #s to actual models the springs are installed on from
the factory OEM. Or crawl under a few mustangs at the dealership
and read the part #s off of the stickers to get a good idea of what
part # comes on what model of 05-08 Mustang.
THIS might help.

 

OK....... I have BBAA...... (2007 Pony Package/Manual). That tells me nothing about spring rate.

I would really like to find a PDF/document with the lbs/in cross references for:

Fronts:
AA
BB
CC
DD
FF
GG

And rears:
AA
BB
CC
...through.....
MM

What if I said "Please"? :-)

 

The only post I've seen referencing stock springrates are:
https://mustangforums.com/forum/show...+shelby&page=2
Post #19. Those are GT rates.

A sticky with the springrates of all the available springs would be a great thing, starting with the stock rates.

 

that would be cool. where do you even find that kind of information?

 

Fords DataBase.
Get a Ford at Job and the info would be yourns.

Suspension specs...

 

I have seen that sheet, and I question what the spring rates really are.

It would take somewhat unusual suspension arrangements to provide wheel rates at both ends of the car that are consistently greater than the springs' own rates. Conventional MacStrut suspension wheel rates are about 90% of the spring rate, and the (two-wheel) ride rate for coil springs mounted on the axle tubes is equal to the spring rate.
