Looking to get some new suspension. My car is a '07 and I'm still running stock. I'd like to drop it an inch or so. I am currently looking at the Strange Single Adjustable Rear Shock (https://www.strangeengineering.net/p...shock-ea.html/) and the Single Adjustable Rear Shock (https://www.strangeengineering.net/p...shock-ea.html/) along with thier Strange Single Adjustable Front Strut (https://www.strangeengineering.net/p...strut-ea.html/) and was wondering/hoping if anyone here had any of these two and could give me more info about them since their site doesnt say much. Like is it for a V6 or just a gt? How do you like them? Any issues? I like the fact that you can adjust it!!

Also looking at the Steeda (https://www.steeda.com/steeda-mustan...-555-8414.html) and FPRP M-18000-A or should I go with M-18000-C?
Any suggestions on springs?
Im still new at this and learning/read about it.

 

this is one of those areas where too many options makes it hard to sort out . . . . to narrow it down a bit, think about:

• how much drop do you want? about an inch is "safe" without creating any major suspension geometry, or road clearance, issues . . . but it you want it to look "slammed" you need more like 1.5-2" drop
• will you use the car on track, or only on the street? for road track you want extremely firm springs and shocks; for the street you want a more compliant ride, closer to stock; for a drag car I think you want everything very soft for weight transfer to the rear
• do you want the ride to be stiffer or about the same as stock? similar to above, depends on how you like it and what you will be doing with the car
• do you need adjustable height or damping? would you actually play around with this, or just leave it alone? adjustable damping is most useful for the road track, where you want to stiffen everything up for the track and then soften it for the ride home

 

Thanks Bert for the responce and for the questions. I never asked myself these things and was just looking, getting all wrapped up in whats good for my car.
But to answer your questions:
I just want to drop it 1 to 1.5 inches.
I will go to the track rarely but it is mainly for the street.
I want the ride to be closer to stock, but I dont know what a stiffer ride feels like. Maybe Ill like it maybe I wont.
I prefer adjutable damping since I want to fine tune what the car feels like when driving it. Giving it a more sporty feel and allowing it to turn better in the corners.
I am going to go with the Strange. Now I need to figure out springs.

 

for the springs -- Steeda Sport give about 1" drop in the front and 1.25" in the rear, which helps level the car a bit. I had these on my car and I liked them. A bit firmer than stock but nothing crazy; worked pretty well for me on road track and would be even better with a good set of struts/shocks like you are talking about; not too harsh on the street IMHO. I think they are a pretty good choice.

There are a lot of other options, gets confusing and overwhelming trying to sort out the differences. Right now I have the FRPP "P" springs which supposedly give 1" front and rear, but the front looks like it is sitting a bit too high to me. Like a dumb@ss I forgot to measure to see how much drop I actually got.

 

Since you like I are Canadian, I found limited access, Ted at Mustang Direct has been good, and I have bought quite a few things off of him but I have been doing the conversion from CAD to USD and bought my suspension through American Muscle, SR springs and Koni shocks and struts GT500 lower control arms and the list goes on, I found even with shipping it was cheaper than getting it up here. an example is the one piece driveshaft is over $900 in Canada and over $600 from the US. Good luck in your search.

 

See the signature. Wanted to see what others maybe said first. I feel maybe I can contribute now...

I like my setup. I could use probably some caster/camber settings for better tracking, but I don't track. Also for less understeer, but I don't track. Yet? Well, if I win/acquire enough moolah to rent a spot on a track, sure, maybe then, but I don't need the temptation otherwise, y'know?

I too have the Ford P springs, and I think they're pretty much spot on the 1" thing. Car went down about that all 'round, looked stock, except... not. Just that little bit. I like the raked look anyway, which is why I opted for those. I have the Koni Oranges and they work fine, not adjustable, but they do the job. That set of GT500 bars front and back? LOVE those. They're quite honestly my favorite thing I installed. I have them set full stiff in front. Yeah, I know, weight transfer... not tracking. In the twisties she's a lovely thing to drive. I do have them big wheels and tires on her, which probably helps the traction overall. And the GT500 front and BMR full rear arms/bars I really enjoy having. No hop, confident turning, flickable in traffic or avoiding things in the road... If I need to almost literally put her somewhere on the road, I can, near instantly.

So, *for me*, this is the setup. And I dare say that maybe, just maybe, with just a little tweaking and maybe adjustable shocks, this would track pretty well too. Maybe go middle on the front sway bar... I dunno... Truth be told I only did all that stuff because the front control arms ball joints were doing the thing what they were doin' back then, and the rear control arms rubber bushings were toast too, and I wanted to get rid of wheel hop, and the wheels became a thing, and... yeah, well, it just kinda happened at that point. No ragrets. Love my setup. Again, for me.

For what this way not-pro guy's opinion is worth. I think they should have come like this factory, but I'm insane, as it says on the left there.

 

Just curious for making the switch from the Steeda Sport Springs to FRPP "P" Springs. Knowing that both give pretty much the same 1" drop in the front and by just .25" lower in the rear for the Steeda Sports vs the FRPP "P" Springs, I'm not quite understanding what other differences would be involved between them. When you mentioned the Steeda Sports being a bit firmer than stock, but nothing crazy, were you perhaps looking for a softer rated spring that provides a less stiff/more comfortable ride than your Steeda Sports Springs? If in fact, the FRPP "P" Springs are less stiff and provide a more comfortable ride over the Steeda Sport Springs? then I would definitely consider these as a possible replacement for my current Eibach Pro Kit Springs. Otherwise, the Steeda Sports would be my top choice. I've also considered BMR Sp009 lowering springs which also are known for having a softer spring rate, but supposedly lower the suspension by up to 1.5" which is just a bit too low for my liking. Anyhow, I'd really appreciate any feedback that you can provide between the Steeda Sport Springs and FRPP "P" Springs (Pros vs Cons)

 

Thanks guys for the replies. I appreciate it very much.
I keep reading that the FRPP K and the Steeda Sport springs are for the GT.
So I am going to go with the Seeta Ultra-Lite Mustang Lowering Springs since they are made for the V6 and gt.
Im also going ahead with the Strang adjustable shocks/stuts and will add an adjustable panhard bar (since lowering the car) and the Steeda Heavy Duty Mustang Upper Strut Mounts from Steeda as well.

M05fastbackGT you meantioned that your have the Eibach Pro Kit Springs. I read somewhere that they are exactly the same as the FRPP springs since they make the springs for Ford.

Jcoles I agree, everything up here in Canada is too expensive! It is really ridiculous not to meantion finding Canadian realtailers that sell parts for our cars are few in between. Its why I do lots of research before buying anything and getting it either shipped up here OR going down to NY and picking it up. But since this stupid viurs I cant do that now...I currently have LOTS of car parts sitting in NY waiting for me that I need to pick up!!!

 

They may in fact be manufactured by Eibach for Ford Performance Parts, but are definitely not the same. The differences between the Ford performance M-5300-K vs Eibach Pro Kit Springs are the Ford "K" springs lower the suspension by approx 1.5" both front and rear. The Eibach Pro Kit Springs on the other hand, lower the front suspension by approx 1.2"-1.3" and lower the rear suspension by approx 1.5" Therefore, the lowering specs between the 2 are noticeably different. Also note that Eibach does not offer it's own branded version of the Ford Performance Parts M-5300-P springs which lower both the front and rear suspension by approx 1" At any rate, I can't really comment or confirm one way or the other as to whether the Ford Performance Springs provide a better or less harsh of a ride quality over the Eibach Pro Springs or not thru personal experience despite the fact that Eibach is the manufacturer of the Ford Performance M-5300-K lowering springs and more than likely the M-5300-P springs as well.

 

I switched because the new springs came with the Vorschlag street/sport set-up with the Bilstein shocks/struts and the Vorschlag mounts, not because I actually wanted different springs. Vorschlag sells these pre-assembled, which makes installation very easy (no spring compressor needed) and I figured the extra cost and limited spring selection was worth it for the time/labor savings; and Vorschlag recommended the P springs for my wants/needs.

I can't really tell a big difference in the stiffness on any of these setups. I would need to do some kind of objective side-by-side comparison to really tell the difference. The P springs are progressive which means they have a softer initial rate, which is supposed to be good for the street, then they stiffen up more as they compress. The Steeda Sports are linear which means they should be a bit stiffer at first and then similar. Again, I can't really tell the difference. Vorschlag has quite a bit of spring testing data on their web page and for practical purposes there is not a lot of difference. They advise that the most important thing is the amount of drop that you want.

I can tell the difference that the car is sitting a bit higher in the front than before, which I do not like; this seems contradictory to what they tell you about how much they drop the car. Unfortunately I did forgot to measure it before I took the Steedas out. I am actually considering renting that **** spring compressor, taking it apart and swapping the front springs to the Steedas. I have heard that the "drop" numbers are not a precise science and can vary widely on different cars; which is strange but does seem consistent with what I saw.

You could check the spring rate test data on Vorschlag we site to get a better picture of the stiffness. It is a little hard to find, I think it is in the "pictures" section in the blog section . . . I would need to look and find it again, let me know if you'd like some more clues on that.

I think the Eibachs are very similar to the Steedas but not sure; have heard rumors that Eibach makes them for Steeda but don't know if that is true.

 

Gabe previously ran Steeda sport springs on his "13" GT and said the manufacturer is Hyperco, so it's definitely not Eibach. The Steeda Sport/Hyperco springs are a linear rate just as you mentioned, where as the Ford "P" springs are progressive rated as are the Eibach springs. Anyway, knowing that you weren't able to notice any real difference in stiffness between the Steeda sport and Ford "P" springs, I really don't think I'll notice any real difference by replacing my current Eibach pro springs with either the Ford "P" or Steeda sports to be honest with you. As for your current Vorshlag setup, I am somewhat familiar with their street/sport kit and really curious as to what the part number is for your Bilstein front struts.. By any chance is the part number stamped on the front struts, part number 35-128717? If that is in fact the correct part number? this would be the same part number for Bilstein B6 HD front struts, according to the Bilstein website. Meanwhile, if you could find this info out for me? it would be really helpful and appreciated.

 

yep, I have been wondering about the great "shorter strut" mystery for a while too . . . would need to take a wheel off to look at the struts, but I might be able to read the part number in a picture, will take a look later

 

Same here about the shorter strut mystery too. From what I saw in the Vorshlag display images on their website, it does appear to have the Bilstein B6 HD part number 35-128717 stamped on the strut. If by chance the part number for the Bilstein struts aren't listed on your sales invoice? Then the only other way to find out for certain, would be to either take a wheel off or turn the wheel to full lock away from the strut to read the part number

 

I found a picture . . . . part number looks like 35-128717 but there is another number VE3-C871+ which could be some kind of custom variant or something, don't know.

So it sounds like the "shorter strut mystery" is a myth, or perhaps pure intentional BS, depending on how you look at it. I have seen some other posts that also say the part number the Vorschlag sells is the same normal part number that you get anywhere else for a Mustang GT. I think the price works out about the same; however Vorschlag will not sell their "special shorter struts" without the complete spring and mount kit, which is what I bought. I did it mainly for the mounts and the convenience, but it is a little annoying to know that I could have just bought the mounts and assembled with my own (new) struts and springs. Like I said before I might end up swapping the springs back to the Steeda Sports after all.

 

According to my research, the part number stamped below 35-128717 is part of the old one. The only difference is the old part number had F4- VE3-C871 H0 vs VE3-C871+ on the image you posted. Anyhow, I suppose the only way to find out for certain, is to contact Bilstein directly by providing the VE3-C871+ number to determine if this is in fact some kind of custom variant of the Bilstein B6 HD damper in regards to the shorter strut mystery or if it's the very same? I've also seen and participated in other Mustang forums which also state the Bilstein part number included with the Vorshlag pro/street kit, which is the same normal part number that you get anywhere else for a Mustang GT. At any rate, this was my main reason for contacting Vorshlag in regards to the shorter strut mystery claims. Needless to say, they also told me they do not sell their "special shorter struts" without the complete spring and mount kit, and then after requesting the part number for their supposed "special shorter struts" not only did they refuse to provide the part number, but they also refused to sell me their " special shorter struts" along with their shocks without the complete spring and mount kit as a stand-alone option, despite knowing full well that my car already has lowering springs, including GT500 strut mounts. Therefore, what's the point in having to buy a complete spring and mount kit, when it isn't necessary, to begin with, lol. As far as I'm concerned, this alone was more than enough reason for becoming suspicious in regards to the Vorshlag "shorter strut mystery claims" which also brings to mind the most important question, which is what other legitimate reason would they possibly have for refusing to provide or reveal a specific part number, unless they obviously have something to hide, in the first place lol.

 

I went through pretty much the exact same conversation and scenario. In the end I decided to go for it, knowing I might be paying extra for nothing.

Anyway it is a good setup, their upper strut mounts are gorgeous, and it was very convenient to have the strut/spring/mount pre-assembled; and I'll never know exactly how much I paid for that convenience, LOL.

Back to the OP VGMStudios -- hope you like your new set-up, let us know how it works out for you.

 

I'm glad that it's a good setup and working well for you, however, after the conversation I had with the company owner, he failed miserably to earn my trust as a potential customer. Needless to say, if the vendor/owner is unable to provide excellent customer service in both a professional and respectful manner by addressing my questions and concerns in an adult, honest and straight-forward manner? IMHO, they're not worthy enough to deserve my business, to begin with, despite how good their products may happen to be. That being said, just my $.02

 

Bert!
Just got off the phone with John from Bilstein tech support, located in California. After providing him with the VE3-C871+ number from the image you posted, he said all that is, is just the manufacturing number and confirmed is the very same Bilstein B6 HD damper you can purchase from any other vendor/distributor for the S197 Mustangs. He also fully addressed my questions by confirming that you do in fact have the Bilstein B6 HD dampers and not some "special custom variant" that doesn't exist which Vorshlag Motorsports claims are 1.25" shorter.

Meanwhile, for what it's worth, just wanted to follow up by providing you with an update.

thanks for the update . . . good to know, though disappointing to hear that it is BS, I guess you can't trust anyone these days

 

Also spoke with Caleb from Summit Racing. He also confirmed the shorter strut mystery which in his exact words are "Bogus" So there you have it, from yet another reliable source.
