Steeda Sport Spring vs FP-Y

[ptrezby]

Getting ready to change out the springs and dampeners on my 2020 HPP Ecoboost and I've gotten myself into an "over analyzing" it situation. I've got the FP Track shocks already (got a good deal on them) ... but I'm going back and forth on whether to pair with the FP-Y spring or the Steeda Sport Progressives. The car is a daily driver, and most likely will never see the track ... but I do want better than PP performance (just because). Yeah, I know I'm splitting hairs and either spring is more than fine. Also, I have the Steeda Camber plates ready to install when I decide on the spring.
I've scoured the internet for a comparison of the two springs, but not really finding anything .... I guess they are different enough in nature to not lend to an apples-to-apples comparison. Anyway, just thought I'd reach out for opinions before going forth. Thanks in advance!

Well I don't know anything about the Steeda, but I have the FP track shocks kit and the FP progressive springs and I am very happy with them.

Lowered the car about 3/4" in the end, it looks really really good. I went from a stock GT suspension so there was a noticeable difference in feel for me, but I still like the ride.

Also been doing research and I'd go with the frpp y springs since those shocks and springs are meant to work together. I'll probably be getting the street x springs

FP all day. Ford vs Steeda R&D hours are 10 to 1. More R&D means better product every time.

Not knocking Steeda. They probably have a great product for the time they have into them. But Ford spent millions of dollars in designing their car, and testing it.

Ford Motor Company focuses on building cars for the mass market, their emphasis on the performance division may not be as pronounced as it is in the aftermarket industry. They don't always have the resources to test as much as the aftermarket.

I want to assure you that Steeda, as a company, dedicates significant time and resources to testing our products.

Through our extensive research and development efforts, as well as our unwavering passion for racing, we continually test various combinations and configurations on our test vehicles.

This ongoing process allows us to refine and improve our products, ensuring that they meet the highest standards of performance and quality. Rest assured, our commitment to delivering exceptional performance is deeply ingrained in our DNA.

Another thing that sets up apart is the ability to put you in touch with our suspension experts to help guide you in the best spring for your application.

With that being said, send me your contact info to [email protected] & I will connect you with Rod or John in order to help with your purchase decision.

Lol, Ford Gt, gt 350/r, gt 500, etc are everything except mass market cars
Yes, most of ford cars are “mass market “ but Ford have all the money and engineering resources necessary to develop some unique cars and performance parts, way more than any aftermarket parts manufacturers

... I do want better than PP performance (just because).

Frank, How much performance do you want? PP2 or GT350? Are you sure you want progressive springs and not linear ones?
Do you want to prioritize the "look" from the drop or the performance from the spring rates? Comfort from the progressive or performance from the linear?

The 200/800 spring rates with the FP Track dampers will bring the ride frequency very close to the PP2.

I have the Steeda Minimum Drop paired with the FP Track Dampers. The ride frequency math shows very close to PP2. I love this setup, it is perfect for me.

I acknowledge and respect your perspective.

But ... with our extensive experience of over 30+ years in the industry and our collaborations with OE partners in manufacturing parts, we have gained a deep understanding of the intricacies of the industry & the OEs limitations.

Agree to disagree.

Thanks everyone for their replies, I appreciate all the opinions.

I guess I've come to a rather odd solution to my question: I went ahead and ordered both spring sets and I'll try each out to see which suits me best. Figure I'll run the FP Track Springs/dampers for a few weeks (give or take) and then switch out to the Steeda Sport Progressives with the FP track dampers and see what happens. Yeah, its overkill, admittedly, but I'm a data analyst by trade so I tend to get wrapped up in being able to quantify things (it's a bit of a curse, honestly).

Thanks again, hope y'all have a great Memorial Day weekend!

Get a few sets of splined struts bolts and nuts because getting them out damage them

You are absolutely correct with what you've stated concerning the ride frequencies of these springs. The problem is that the ride frequency ratio which these springs provide have F-all to do with making our cars handle well. In fact, it actually guarantees that the car will never really handle well by dictating the front too soft and the rear too stiff. The overall stiffness levels of the 200/800 combo isn't bad, it's just poorly proportioned.

I will defend Steeda a bit on the development side. Ford isn't taking cars to actual races, that's for damned sure. You can't knock Steeda in terms of putting their money and effort where their mouth is. I just disagree with some of their tuning philosophies.

The Ford kit has a stiffer front and softer rear. That's why it's the one to get, IMO. In hard driving the stiffer front reduces brake dive and increases stability and response on corner entry while the softer rear gives better traction on throttle. Even though it shifts the roll couple forward, I feel a stiffer front spring improves front grip, probably through less travel/better camber control.

The problem I have with all of these spring packages (not just Steeda, only the old FP version didn't do this, the new one does) is they jack a bunch of rake in the car so it's wagging it's a$$ up in the air an extra 1/2" or so. This is ridiculous and makes the car much harder to drive fast. If you load the front of the Mustang with the brakes, the car will turn. Period. If we stick a bunch of rake in the car and under-spring the front, now it's even more prone to entry oversteer (a trait which is bad enough stock) so you don't even *want* to load the front because it feels like the damned thing wants to swap ends.

Everyone has botched the canned spring packages if I'm to be honest. Too bad.

Given that steeda offers a variety of springs that serve different functions i'd say check out all the offerings first. I'm strongly considering the dual rate springs from steeda because they don't drop the car much and i haven't heard anything but stellar reviews on them.

Do you ever think, "The rear of this car is really soft." You shouldn't. It's not. Do you ever feel the rear have a quick bouncing/hopping motion? Most people do. That's because the spring is too stiff and the chassis is bouncing on the sidewall of the tire.

If you're running tires (slicks) that can accept that type of spring rate, then maybe that's one thing, but on any street tire, the effective limit you can use is not all that high. I don't really understand trying to push rear spring stiffness higher. It's not only unnecessary, it's generally unwanted.

I would upgrade the rims / tires before you do anything else, then stiffen up chassis. It's your money do what you want but throwing $$$ at suspension parts before the others is a waste IMO.

its a few things working in concert.

1. the stock suspension has hidden spring rate built into it with the way the bushings bind
2. the stock dampening isn't sufficient on the non magneride cars
3. as we all know the rear moves around a lot making it feel squishier than it really is

a lot of people go stiffer springs and thicker sway bars. this adds to the spring rate.
steeda actually suggests running a smaller swaybar in the rear if you run their dual rate springs for this reason.

i notice a LOT of pitch with the stock suspension when bombing down less than perfect backroads. to correct for this i need stiffer springs and matching dampeners. the sacrifice will be a harsher ride, thats why i want adjustable dampeners to help with this.

its not rocket surgery but ya gotta factor it all together.

im not a steeda fanboy either, i had a broken swaybar they wouldn't replace back in the day that left me a little sour but that was a long time ago. nobody else has anything like their dual rate springs.
