I want to lower my mustang 1.5-2", reduce nose dive and improve handling. I do not want to go all out and replace the suspension just yet.

I know there are good springs out there but a lot of reviews do not specifically describe the difference between the track pack and aftermarket springs.

Interested to see what track pack owners have done.

 

I am also considering the ford racing adjustable handling pack, is it a noticeable step up from track pack suspension?

They come with P springs, I want the K springs bigger drop, is there a reason who ford never gave customers the option to choose?

 

I have heard more than one track pack owner say they went to Steeda Sport springs and they were happy with the result. But I think they probably replaced the struts/shocks also at the same time.

Be aware that too much drop is NOT good for handling, as I understand it. About 1" drop is supposedly the most that will not throw off the geometry of the suspension too much. Disclaimer: this is what I have been told / read, I am not an expert on the subject.

 

I'll be doing suspension this spring on my TP car.

The difference in factory setup is slightly stiffer spring rates, and corresponding change in valving for the struts to control the springs.

Aftermarket springs have MUCH higher spring rates.

Stock GT spring rates: 123lb/in F, 156lb/in R
Brembo/TP spring rates: 131lb/in F, 167lb/in R
Steeda Sports: 200lb/in F, 175lb/in R

I only want to drop ~1" or so and my current plan is to go with Steeda Sports + adjustable Koni Yellows and Steeda CC plates and PH bar. I'll leave the sways alone for now.

 

One other company to consider is BMR, particularly if you track you car.

They have handling springs which drop you ~1.5" and have very stiff spring rates, 240lb/in F and 200lb/in R

 

I used Eibach Pro and have good all around handling that is a bit stiffer that the TP springs. Stance is on the mean side.

 

Have a 2014 Track Pack. Can't tell you what it was stock but my car came from the dealer with Steeda sports, Steeda HD strut mounts, and Steeda Panhard bar and brace. The car handled great but I felt the stock track pack shocks were not a good match for the springs. Within a few months I put Koni yellows in which really complemented the springs. Felt like a whole new car and even took the bumps better. My advice would be that while you can get away with just springs, you should also really consider a set of shocks to go with it as well as either the gt500 or Steeda HD strut mounts. Stock ones are garbage.

 

Let me know if I can help assist with your build & pricing ... you can reach me at tim@steeda.com.

Glad to hear it ... our Steeda parts are a great compliment to any package!

We have found a certain sweet spot when lowering the vehicle ... you don't want to go too low since the suspension won't perform as intended & other upgrades will have to be done.

I put on SR springs with Koni SRT.T's 2 seasons ago. They've worked just fine - great for the street, soft for the track at my current driver level. But they've been great overall

I'm looking at BMR for a MUCH stiffer spring setup next season - in the range of 500 front, 250-275 rear based on research I've done and where I want to go with the car. Probably a bit much for the street, but it should work a lot better at the track with my essentially full weight car.

 

500 lb/in front? Holly! That's a stiff spring

 

 

My thought too...obviously getting after it out there...good for you! Those springs are gunna suck if you drive it on the road though! Have you thought about higher bar rates instead?

In the alternative....

I have a '14 GT with the Track pack, and I've done some fairly extensive work on the suspension and chassis. What worked best for me was a set of OEM standard (not Laguna) Boss 302 springs from MY 2012-13. It's a Goldilocks solution: not too low, not too stiff, interfaces very well with Koni Yellows on track, street and mountain road situations. The springs were very inexpensive from the dealership: $48/front pair, $52/rear pair.
