FRPP Handling Pack Suspension

[Todd15Fastback]

WOW...Thank you for posting this. Some VERY valuable pictures and insight to the suspension...The comparison photos are amazing. The sway bar looks identical except for an extra mounting hole which I am sure is what makes it stiffer. Also without knowing the valve'ing in the Strut I would swear they are the same just powder coated blue. What will be really telling is does it remove the bouncing.

However, the one time use for the bolts is something that if true we should all be looking at.

Can't wait to see more...THANK YOU AGAIN!!!!!!

Added thoughts...

The Steeda Sway Bars look MUCH thicker...anyone know the size of those compared to the FRPP? Also, Not sure looking at the Struts in the un-loaded position indicates drop. I BELIEVE it is the spring compression that will determine ride height. I am no suspension specialist, so maybe someone can chime in on this...I am TORN personally what to do to fix my bouncing suspension. I was leaning this way, up until this post...LOL!

Go with the Steeda progressive springs, add the sway bars and their billet mounts and don't look back.

The ride with these progressive springs is perfect. I swear it is. SC Pilot will agree, I believe.

install would be just like this just no spring compressor needed

I definitely agree with Todd and Clink. The Steeda Sport Progressive, sway
bars and mounts... perfect. As with anything in life. YMMV.

Is there a chance you can check thickness with calipers on the PP sway bar and springs compared to handling package pretty please . If thicker I will be getting it and if not then I won't lol

Asked my friend to do this when he get a chance in next couple days. He said his set of calipers at his house are broke, so he needs to get a pair from work, or get another set for the house. I will update as soon as I find out.



On another note, here is a pic of an additional item that comes with the Handling Kit... I am not sure of the details why, or how they will improve anything.

I wish I was there when the kit was started at the dealer.. i would have got more pics. I never anticipated helping install the kit... the stealership was supposed to, and it turned into a mess. But I will report back whatever feedback/measurements that I can.

The Detroit Muscle video mentions how big the sway bars are.

4:23 mark in video
Front PP Sway - 32 MM Diameter
Front Ford Racing Sway - 37 MM Diameter

8:58 mark in video
Rear PP Sway - 22 MM Diameter
Rear Ford Racing Sway - 25.2 MM Diameter

Take that for what it is worth, but I guess they measured them before install.

I really want to know if the struts/shocks are more aggressive and the spring rates, but that info probably isn't going to be easy to get. I guess we can wait for customer reviews to see their thoughts.

They actually have an image up on the Ford Performance site now that shows all the parts.

Thank you for all the data...I went back and looked through a Steeda Post which had their Sway Bars. I built a quick table to put it all in one place:

Looks like Ford Handling Package has thicker Front, and Steeda is Thicker Rear...Both ~3mm larger than the other...Question now is how are the FRPP Front Shocks and Rear Struts when paired with the FRPP Springs...Equivalent or better than the Steeda springs when paired with PP Shocks and Struts...Sway bars being so close, in thickness, it comes down to adjustability on Steeda being better with 4 holes. Probably cutting hairs for a normal drive, track Steeda would probably be slightly stiffer. IMHO.

I need to stop lamenting over this, and just frigging buy something!

Here is the Steeda Thread and measurements:

Post #49:
GT Performance Pack Sway Bars:
Front: 1.25"
Rear: .875"

Steeda Adjustable Sway Bars:
Front: 1.375"
Rear: 1.125"

Very interesting. The ford front sway bar is for sure thicker than steeda but then the ford rear is thinner than steeda. From the numbers posted of course. I wonder if the ford handling pack shocks are a little shorter than stock since the springs are shorter

 

[Todd15Fastback]

Good information to see the size comparisons between factory PP, aftermarket Ford Racing and Steeda.

What I like about Steeda is the amount of adjustments you have. 4 upfront and 3 in the rear. I bet the Steeda bars are higher quality as well. At least that is my guess

 

[Rv-Junke]

Yeah, I don't disagree...odd the size deltas and Steeda beefier in the rear. Maybe David @ Steeda will weigh in ..

[Shark77]

The front to rear delta is what I'd look at...

PP = 0.393
FRP = 0.457
Steeda = 0.25

Assuming material is the same, it looks like the FRP is setup to have more oversteer out of the box.

My guess is that Steeda is trying to reduce a lot of roll and keep it fairly neutral to understeer.

Looks like Ford Handling Package has thicker Front, and Steeda is Thicker Rear...Both ~3mm larger than the other.

Just keep in mind that tube diameter is but one parameter of many that affects roll stiffness. Tubing wall thickness, type of material, length of lever arm all affect stiffness as well. And then you have adjustable lever arms on the Steeda!

In short, we have no idea which of these packages is doing what to handling balance, except the manufacturers are all saying they are making it better, or "optimizing" or something. And "optimum" varies depending upon the car, what you want to do with it, how you drive, the tires (square or staggered) and a bunch of other stuff.

We would be well served by more complete stats including roll rates and percentage increase/decrease over stock. Then if you think your car is pushing, you can get a stiffer rear bar. And if you think it's too tail-happy, you can get a stiffer front bar or a little looser rear bar. Tuning! It's all about tuning, not about hype.

I can tell a big difference between the stock PP suspension and my Steeda setup. I can carry a lot more speed into turns and feel more confident that the ass-end is not coming around vs stock. The front turn-in is even better vs. stock. The car just goes where you point it. Everything is sure footed. I am still on the stock PP wheels and tires, too.

See, that's really good info and I am glad to hear it, because if you look at bar sizes, the Steeda front is 10% larger than the PP while the rear is a whopping 28% thicker, which on its face would suggest Steeda is designing a drift car! Yet I hear you saying it's a little LESS prone to oversteer than stock. So either bar stiffness is not proportional to bar thickness, or the spring rate balance is different than Ford's, or both.

Just reinforcing the point that you need to know what the parts are going to do, don't just read the numbers. And most of all, don't grab Eibach springs, Steeda sway bars and off-the-shelf Koni dampers and expect it all to play nice together. That SELDOM happens. Someone needs to design an entire suspension to work together. Not saying the components can't come from a variety of sources, just that doing that takes a lot of study and testing to get right. Steeda is really good at the integration. Other firms are, too. But the Summit Catalog (not to pick on Summit) is not an integrator and you can certainly pick badly-matched components that will all bolt on really nicely. Be careful out there!
