GT350R Springs for GT (high rate, minimum lowering)

[sredish]

So a little more frustration. I'm trying to look up part numbers on Levittown using the type of vehicle (GT350R) and I get info on them that matches with correct description of what I'm looking for but then they're not matching what I've been told they should be or what I'm reading here.

For instance:

fr3z-5310-g - the description for this part is: "Strut for your 2016 Ford Mustang Shelby GT350 with a 5.2L V8"

but we know it on here with a U suffix and i'm told the G is for a base GT. there's also a few things with the seats and stuff.

ALL for GT350R

Front spring
FR3Z-5310-M (levittown lists this part as a "shock absorber")

Rear Spring
FR3Z-5560-S Left (left what)

FR3Z-5586-C Left upper rear spring mount (It lists this just as AntiSqueak... no upper or lower)

It does this for rear left upper and lower "Insulator" respectively
DG9Z-5586-A
E1GZ-8321-A

It lists this for strut mount
FR3Z-3A197-B
front seat for spring
FR3Z-5A306-A

I think we just need an accurate compiled list for front 350 components

There's definitely an error if you try and look it up yourself. It is the U suffix.

Great info here, I wasn't sure if the r rear springs were any lower than the regular gt350 r springs.

Just ordered!

Did you get the GT350 R fronts and the GT350(or R - they are the same) rears?
I would like to hear feedback on this combo. What dampers did you have in mind?

 

[sredish]

this is the order I'm about to place. I may wait on the struts themselves to see what options or things may pop up. But 350R front coils and 350 rear springs with the mounts and isolators to put them together prior to swapping them out.

Spring - Front 350R
Part Number: FR3Z-5310-M

Spring - Rear 350
Part Number: FR3Z-5560-S

Antisqueak - Rear Spring
Part Number: FR3Z-5586-C

Spring Seat - Front
Part Number: FR3Z-5A306-A

Strut Mount - Front
Part Number: FR3Z-3A197-B

Spring Insulator - Front
Part Number: DG9Z-8321-A

Not trying to discourage you...but I had been researching this for a while before I did my setup, I got nowhere with the upper/lower seats PN.

can you post up the part numbers that you have for what items when you get the chance?

also, not that it's totally the topic but besides an additional 0.5" +/- drop, how do you all think the rates of the track coils/springs compare in feel and handling to the 350 springs/coils? anyone have any opinions on that?

Rear Spring
FR3Z-5560-S Left (left what)

It means the spring goes on the left side of vehicle.

FR3Z-5586-C Left upper rear spring mount (It lists this just as AntiSqueak... no upper or lower)

Upper spring mount/antisqueak are the same thing. There is one for the left spring and one for the right spring.

It does this for rear left upper and lower "Insulator" respectively
DG9Z-5586-A
E1GZ-8321-A

The lower antisqueak is the same in both GT and GT350.
The front spring components are interchangeable left or right (springs, dust boots, mounts).

 

[Niz55]

All gt models 16 and up get the pp strut mounts.

I would not use two left springs, the right spring will fit fine that is why there is a left and right upper antisqueak. The front spring components are interchangeable left or right (springs, dust boots, mounts).

The rear lower control arms look nearly identical

GT and GT350

The rear lower control arms are NOT identical. The spring pockets on the right side are mirrored on the GT350 vs. being the same left and right on the standard car. The rear springs for the GT350 are wound in opposite directions left and right, vs. the same direction on the standard car. This is why you have to use two left springs if you want to use GT350 rears. The shock mounting to the arm is also quite different on the GT350.

Precisely, I couldn't get confirmation of the PN of the seats and confirm fitment...which is sort of lame since my contact works in Ford, just not in SVT. I know that if I bother him enough, he will eventually find out, no I didn't.

The track pack springs are progressive, at least on the rears, supposedly they give a more comfortable ride at the expense of pure handling capability. Because the springs have a low and a high rate, the actual rate will vary depending on the compression distance...vs the always predictable rate of the linears, which are close to the "ideal spring" used in calculations.

And, I heard they are Eibach, I don't know if they are the same rates or not. There a lots of folks that have them installed, and so far the feedback is positive.

Now that I had my setup done, I think I could possibly do like quarter inch more and still be borderline acceptable...but half inch, no.

I have a 350 tp


The rear springs are different. Gt350 is more progressive, the gt350r is more linear

Say what?

They're all linear. The 350TP has a little softer damping, softer front springs and rides about 0.5" higher than the R.

placed the order.

i'm curious to the ones that have this setup? how is the ride overall on city streets? is it really harsh? I've heard a couple say it's not too bad then i'll read a review stating it's miserable. I'm not one of those, don't want to mess the ride up guys. I'm fine firming up but I don't really want to make it annoying and overly harsh.

The rear 350s are rate of 800 where the SP082s are 740. The 082s might be the ticket, especially for a EB car.

The experience doesn't get much better on city streets or freeways. Even with the MagneRide suspension, the car pounds over bumps. The rear end is particularly harsh. This may be the first generation of Mustang with an independent rear suspension, but Ford needs to take some lessons from the Chevrolet Camaro on how to dial it in. And the drive modes don't help either. The base comfort mode is all you want to use for anything but performance driving. Turning up the wick to Sport or Track modes just makes this car hop and jiggle and pound even worse.

914 lb/in, not 800. BMR SP088's are 800 lb/in.
