My 2015 GT (non PP) already comes with sway bars. Is there any real benefit in installing aftermarket ones?

 

Depends.

Let's start with yes their is value in upgrading to larger, stiffer, adjustable bars, but what handling problem are you having now? Sometimes progressiive springs and/or shocks/struts might be what you need depending on the issue. So depending on what you want to fix there is more or less value.

Explain what you don't like about the current handling and then we can answer if they will help with your specific problem.

 

I don't guess there's anything "wrong". This is my first Mustang, and first car with noticeable oompf. I work with a couple of Mustang "nuts" and this is what they suggest. However, if the upgrade is not worth it, I would like to spend the money on something else. Thanks

 

Of course this is my opinion...
I had a 2008 V6 Vert that did not come with a rear anti-sway bar..it helped tremendously when i installed an Eibach Kit.
I sold that car and kept the Eibachs and put them on a 2013 V6 Vert. While yes it "stiffened" the car slightly I can't say it helped the handling at all.
I bought a 2013 GT/CS and only replaced the rear sway bar end links with heavier ones and it helped quite a bit.
So in my opinion the weak link is the end links.
The bars themselves are adequate for most applications but the end links seem to be what is lacking on the factory bars.

 

There can be, but it kind of depends on how you use your car (or how you might be thinking of using it).


Aftermarket bars are typically stiffer than the OE bars and can be used to dial out understeer and/or improve cornering and turn-in response. You do have to be driving the car quite a bit harder than "average traffic" for this to amount to much.


You will reduce the amount of cornering roll a little, which will tend to improve tire life (especially outside shoulder wear rates). When I say "a little", it's a small enough amount that you probably won't notice much difference in normal driving. The car will take a set a little more rapidly, which you probably would notice.

Thanks for the responses!

 

If you are looking to improve the handling characteristics a good set of Dampers and Springs would help way more than (anti)sway bars.
