Oh wow, that drop looks near perfect. I would love to know how these ride in comparison to the stock performance package springs. Are they linear rate?

I would love to see a consumer review on these

I would say it's probably similar to the performance package, but lower of course. These are a linear rate.

We will be working with more local customers to get more feedback and reviews on these. As of right now they are on our shop Mustang GT and daily driven on.

Do you have them for the ecoboost ?

We are currently offering these springs for all 2015 Mustangs (V6, GT, and Ecoboost). But do not have any specific for the Ecoboost, we are still looking into that.

I just went to your website, is it the same spring for all 3 cars ?

 

[wildcatgoal]

They'd fit an Ecoboost but the drop would be different. I believe it's like a 300 lbs. difference between the base models of each car, most of that weight up front.

What's the spring rate on these?

And thank you for not coloring them bright red or some other ridiculous color. Please also consider offering them in black. There's a lot of people that don't feel the need for their aftermarket parts to be seen.

Thats exactly what I was thinking. All the other manufacturers have different springs for the ecoboost. They look good on the GT

The springs would all be the same fitment, but yeah the weight difference would cause the drop to be different.
We haven't tested the production set out on the Ecoboost yet, we want to do that first and then decide if we need to make adjustments and create a new set just for that car.
We took a look at the OEM suspension during development for all 3 motors, but basically made these springs based on our Mustang GT here for appearance.

The spring rates are

Front: 6 kg/mm (336 lbs/in)

Rear: 16 kg/mm (896 lbs/in)

Love the drop, what is your recommended geometry set up? Any chance of publishing those figures please?

I'm not too sure how the Mustang GT was set up here, I'll see if I can find any info. Anything specific you wanted to know about?

 

[Lone Survivor]

Toe, camber, thrust? Just interested what the recommended set up would be, compared to stock, or others? A lot of people drop their cars, but pay scant respect to geometry that will affect ride and tyre (sorry tire) wear.

That car looks killer BTW, but sometimes it's not all about that ;)

I just talked to the techs and we did not get a final alignment yet, they are still testing more suspension stuff so I'm not too sure actually. But if/when it's done I'll try to get more info on that.

 

[shelbywannabe]

Why are these on the market when it seems like no testing and final adjustments have been made ?
