I used their pro kit on a regular GT, I thought the rear shocks were a little on the hard side. I like having the struts/shocks adjustable.

I have the Eibach Pro Street kit. Great stance, little clunky and rides as you would expect. I like it

 

Can you let me know what you mean by little clunky? That's what I'm trying to avoid that I'm now getting with the stock suspension.

I also have the Eibach Pro Street-S kit, fully adjustable height, and I can say mine is "clunky".

Ok.... I guess that's out then lol. Is there anything not to make this car sound like it has 200,000 miles on it?

 

I had the FRPP pack and liked it very much. No clunking.

 

I have the Ford Racing lowering springs, Eibach anti-sway bars and Tokico D-Spec adjustable shocks, excellent combination, not clunky. I had the Eibach pro springs and just found that I needed more clearance in the rear for drag radials, but thought their ride quality was good, also have a vert with subframe connectors and other added weight, which made it ride lower in the rear. I did speak with Eibach reps and I ordered this setup, http://www.americanmuscle.com/eibach-multipro-r1-coilovers-0510gtv6.html
I was not patient enough to wait for my setup to be produced, I was told they make them after they are ordered, so went another direction. If you will get into drag racing the double adjustable, for like $400 more would be better.

 

I upgraded to the Eibach Pro-Street S, adjustable coilovers, mine is stiffer and lower than stock but improves handling and NOT clunky. SAI uses this kit on Super Snake conversions so it is proven.

A person who is looking at this Eibach Pro Street-S coil-over adjustable suspension also needs to be aware of some differences. When I was searching for a spare "correct" Eibach coil-over set for my Super Snake I found both of the Front and Rear Eibach Pro Street-S coil-over springs shown below advertised as "Super Snake".............

Front......

Rear......

The "correct" GT500 Super Snake Eibach 35115 coil-over springs are shown below......

Front.........

Rear.........

The "incorrect" (NOT GT500 Super Snake) Eibach 35101 coil-over springs are shown below........

Front.......

Rear.......

The bottom springs are smaller coil and lighter weight, the upper springs are larger coils front and rear and designed for the weight of a GT500, don't get fooled into purchasing the 35101 Eibach set because they are "Eibach coil-overs" and advertised as "GT500 Super Snake".

Thankfully, when I bought the incorrect 35101 set "advertised" as Super Snake (and got them at a Great price), when I opened the box for inspection I knew that they looked different, especially the design of the rear coil springs. When I compared what Shelby had installed on my car and saw the 35115 part numbers and then compared coil diameters, I knew these were not what they were advertised to be and sent them back, but not before I found a correct spare 35115 set for a side-by-side out of car comparison for future discussions.

^ good info. Thanks Robert

 

That is good information.

 

Robert, how do you know if the other pair weren't intended for a later model super snake? Surely the spring rates changed with the lighter engine in the 2011 model. There are two things that change spring rate. One is spring diameter and the second is the number of coils. Reduced diameter would decrease spring rate. Reduced number of coils increases spring rate. Combination of the two, is anyone's guess.

Now the spring height will also determine the final compressed height. Make the coils further apart with the same spring diameter and number of coils and both springs will compress the same amount. The longer spring will have the car sitting higher.

 

I had the same question, so I did some research to verify that the 35101 was not for a later GT500.

Below is a link to the Eibach site and the Pro Street-S kit for a 2013/14 GT500 application, it shows the a 35115 kit as was installed by Shelby on my 2008 Super Snake..........

PRO-STREET Coil-Over Kit (Height Adjustable Only)*| Eibach Springs

I also called Eibach about this part number difference since I had purchased that new 35101 kit at such a Great price ($600), I hated to send it back, but "incorrect for the application" was not going to help me gain a spare correct set for my 2008 Super Snake.

Those springs you have pictures of linked here are not coil-over springs. I'm not understanding your post above.

 

The compare pictures I showed in the post above are exactly what is on my car now, the 35115 and I have adjusted the height at all four corners with the spanner tool.

On the rear of the Eibach coil-over kit, the springs do not mount over the shock as they do with some other brands, they mount on the oem perch and have and adjustment stand which they sit on. If the rear shocks on my car "also" had a coil spring wrapped around them, the rear tire width would "really" be limited in the position that the oem shocks mount. <<I think this is why Eibach chose to use the oem axle spring seat for their adjustable spring location.

The front springs do mount around the strut and have an adjustable perch with lock ring under them.

The struts pictured in the Eibach Pro Street-S link above do not look like Mustang struts or shocks, but it is the part number that matches if a person were to order this set. <<They would receive exactly what I have on my car (possibly a suffix change on the springs since 2008), 35115.xxx.

So the rear is just a shorter spring with an adjustable spring perch. Almost all front coil-over set-ups I've seen on these cars have a 2.5" straight coil-over spring. I haven't seen one with a larger spring taper on one end. Do you have a pic of what the strut looks like? I profess, I have no idea what Shelby installs on it's vehicles. I'll poke around on their site and see if I can find what you're referring to. I think the OP was talking about replacement springs, not coil-overs.

I see a comment was made referencing Eibach coil-overs and that they were used on Super Snakes, but if you point is that Eibach's coil-over offering and Shelby's installed coil-over product are not one in the same, I get it. Shelby probably has some proprietary set-up although their springs are produced by Eibach.

Sorry, I'm just trying to figure out what's going on. If I'm confused, the poor OP must be too.

 

Before I posted anything, a couple of others mentioned they were happy with the Eibach Pro Street-S kits, so I chimed in. One owner before my post also mentioned they had the Pro Street-S and it was "clunky", I guess that is when I chimed in.

If by chance the OP (or anyone else) decides to look into the Eibach coil-over set-up for their GT500, I showed a difference that "some" owners may not be aware of and "don't get burnt" pictures. <<<I have seen that smaller coil kit being advertised as "GT500 Super Snake", and it does not appear to be "GT500" of any year, by the Eibach application guide.

If no one had mentioned Eibach coil-overs before my posts, I would not have posted anything.

The Shelby installed Eibach coil-overs on the Super Snakes are just plain old Eibach kits, nothing "Shelby" labeled or anything like that, but they are 35115.

When I had the rear spring perch in my hand, I played around with the needle bearing washer set-up that helps ease the adjustment process. The needle bearing kit does not come with the Eibach coil-over struts/shocks, so I bought them elsewhere and verified the fitment on the Eibach perches front and rear.

Rear perch shown........

and the adjustable perch sits on the oem rear spring mount location........

I've used similar spring perches made by Steeda and Eibach on my Shelby. I was talking about the front struts. In looking at Shelby's website, they are listing these coil-overs and showing an application for 2007-2014 Super Snakes. I'm assuming they've changed the suspension since they built your Super Snake. Notice how the coil over springs have no taper. That's what I'm getting at.

 

No, unless they have changes brands, it is the same Eibach Pro-Street-S. Here is a picture of my Super Snake order form from mid-2008. Same straight looking springs in the coil-over picture, but what Eibach actually provides for the Mustang application, and Shelby actually installs on the 2007-2014 is what I showed in the pictures.

R

 

Almost everything on Eibach's application guide for a Shelby started with a 35115 prefix, so I think it's just a model designation. It's possible that Shelby changed direction since 2008 on the suspension system it's putting under subsequent super snakes. Even going back to the old super snake brochure, they list "Shelby/Ford Racing suspension w/ adjustable damper".

Glad you found the right replacement springs for your car.

 

The Ford Racing suspension was the standard Super Snake install as shown on my order sheet above. The adjustable Eibach was an option ONLY $100 option, so to me it was a no-brainer, but many owners were concerned they would not know about an adjustable suspension or it would be too rough, etc. Now that Eibach option is like $1000.....

That price differential is very telling. The photo you have shown for your front spring is not the typical coil-over spring you see on the current Eibach set. Measure the I.D. for the top and bottom of that spring and post it. The spring on the Eibach coil-over they have mounted on the struts in their photo is 2.5" i.d. top and bottom. The springs are also tapered on both ends. Your photo appears to be a spring that has a coil-over adjustment on one end, but used a standard strut seat on the top. That's why I wanted to see what your front strut looks like.

Here's photo I took out of Summit's website for the 35115.711. Apparently it uses the same perch in the rear as you pictured. It also appears that they have two different weight springs on the front and rear in this set up. Assuming this is the right photo. However, the mounting points all appear correct to me.

 

It was easier to call Eibach as I did in the past, to verify what is current and what (if anything) has changed.

According to Dave in Eibach technical support the picture you show above is not a 35115.711, it is a 35115.712. Dave said many times the pictures that the vendors use are more of a reference than the actual product. The picture above is the Eibach R1 kit, it is listed for $2970.28 on the Eibach site. The R1 uses universal ERS coil-over springs to spec. from the ERS catalog.

The Eibach Pro Street-S kit, as I have, and is still the optional suspension for the Super Snake builds, is the 35115.711 and what I have on my car is what is still being sold and installed by Shelby ($1827.42 on the Eibach site). The difference in the springs is for "application specific" fitment according to Dave. He said that many/most street owners are not interested in rough/solid mounting points as is the case with most of the track performance R1 and R2 kits. The Pro Street-S coil-over kit contains springs that are application designed to fit the Eibach coil-over mount at one end, and the factory/oem mount/rubber cushion at the other end.

The spare 35115.711 Eibach kit that I bought does not include upper mounts for the front struts, the option would be for the owner to re-use their existing rubber mount on each side, or in my case, I bought the 2011-up SVTPP upper mounts for use if I ever have to take my apart.

There is also a $3541.71 R2 kit with the straight springs that has the external oil reservoirs, again, the solid mounting locations instead of the rubber cushion insulators.

I remember seeing the R1 and R2 kits also available through Shelby, but they are not the optional suspension offered as part of the Super Snake build.

That all makes sense to me. Didn't intend to put you through all that trouble, but very interesting detail on the various kits Eibach offers. I think Eibach is guilty of putting file photos on it's various kits, as I saw the same photos on their website. Did Shelby use the stock strut mounts are do they use something different that allows camber adjustment?

 

It was no trouble, I had talked to Dave before, he has great knowledge of the Eibach product.

Shelby transferred my original 2008 strut mounts to the Eibach struts, that is also why I bought the 2011-up SVTPP mounts, "if" for any reason I have to remove the struts in the future, I will install those SVTPP mounts at that time.

Back when my car went through, the only Super Snake that got CC plates was the NASCAR 427 optioned cars, they got CC plates, special 427 emblems and 427 floor mats as part of that package. I think I received a letter from Shelby asking if I wanted to buy that package for my car, it was like $600............and I really don't like the NASCAR 427 fender wings..........I passed.......and just bought the Shelby CC plates instead.

I bought a set of the plates, but have not installed them. One day the Shelby logo'ed plates will be discontinued, so I picked up a set while they are still available.

MM is who makes them for Shelby............
