Lowering my 2018 GT Non PP

[Jwh]

What else do I need to get with my Non PP 2018 GT when i lower it? Camber?

Also can someone suggest a lowering spring for it? I dont have stock tires either.

I have it staggered with 19 X 8.5 front wheels with 255/40ZR-19 Michelin pilot sport 4s XL

19 X 9.5 285/35ZR-19 Michelin Pilot sport 4s XL

What are you looking for? Why do you want to lower it?

-Better handling?
-Looks?
-Other?

Looks first and foremost and handling. I just dont want to put ONLY lower springs on as ive read you need to do more to properly lower it. This true? I'm learning....

OK, so primarily looks but handling is also important. My advice if you're going to do lowering springs, do new shocks/struts at the same time. It will make the most of your handling upgrade and complement the lowering springs by providing adequate damping. The two need to work together to get the result you want.

Things to keep in mind:

1. Lowering the car more than 3/4"-1" messes up the geometry which will lead to undesirable effects - increased body roll, reduced steering response, bumpsteer, too much negative camber, and poorer ride quality, etc. Now usually lowering springs have a high spring rate than stock which helps to offset the losses in body roll and steering response, but the others will remain.

This is why IMO lowering about 3/4" is the sweet spot for where you want to be. Running a higher spring rate will keep body roll in check and increase steering response. The moderate amount of lowering will not mess up the geometry too bad, although even at that moderate drop it will still change the suspension geometry.

2. Camber bolts or camber plates will give you more adjustment in the front suspension to get your alignment where you want it.

3. Back to #2. You'll want a good alignment. Not just set it "in the green" and you're good to go.

4. There are other things you might want to add to enhance your improved handling.

Such as: IRS cradle/subframe lockout being priority #1.

If you do lower the front quite a bit, you can buy front control arms with extended ball joints which will help correct your front geometry. Then you can have your cake and eat it too. But then you'll also need a bumpsteer to use in conjunction.

5. Think about how stiff you want the ride to be. How much of the road you want to feel. Lowering decreases travel which will inherently make the ride harsher. Stiffer rate springs will be more responsive and make you feel the road more.

I would recommend the following spring options:

BMR 763 min drop, Steeda min. drop, Steeda Sport Linear, BMR Handling Springs, GT350 or GT350R springs. All of these don't drop the car that much and have more favorable spring rates.

You could pair any of those with Steeda adjustable shocks or Ford Performance track. Both will give you great handling and a certain amount of compliance and control that you will want.

If I were you, I'd go with GT350 or GT350R springs all the way around and Ford Performance dampers. Leave the sway bars alone. Do the BMR cradle lockout to stiffen up the IRS. Get a good alignment and you're done.

We have a great spring in our Steeda Progressive Sport Springs - great for handling & ride comfort .. here is a great spring guide you can check out:

The front of your Mustang has no adjustability for camber from the factory. When you install lowering springs, you induce more negative camber into the front of the car. This additional negative camber will cause the front tires to wear on the inside edge and drastically shorten tire life.

To correct this, you should install our 555-8139 Steeda Mustang Camber Plates with your lowering springs.

(Here at our installation facility, whenever we lower a S550 Mustangs, we always use the 555-8139 Camber plates)

The picture above with the car from steeda is the exact look I am wanting. Do you have a recommendation for shocks and struts?

 

[BHRS]

What are the specs on the Steeda car above. Springs, tire size, wheel size and offset. That is the stance and look I'm after as well.

 

[tj@steeda]

Yes, the fixed pro action shocks and struts.

Yes, our Steeda Pro Actions are a great choice we offer both adjustable & fixed - depending on which route you prefer.

Both are great options & you will see a lot of feedback on the forum on the subject - happy to put you in contact with one of our build experts if you are interested in talking about your build.

Best Regards,

TJ

Those are the progressives & were taken with the Steeda Adjustable Pro-Actions. I will have to get the specifics on the wheels, tires & offset.

As TJ mentioned above that is our Steeda adjustable pro-actions paired with our progressive springs. Wheels are Steeda STR 20x9.5 w 275/35/20 and 20x11 w 315/35/20. I will have to get you the offsets in the morning can’t think of them right off the top of my head.

Thank you... with that wheel and tire combo do they rub? Looking forward to the backspace/offset on those wheels.

Any luck finding out the offsets on those wheels?

The 20x9.5s are ET 45
20x11s are ET 59
