2015-2023 Mustang Steeda IRS Subframe Bushing Support System Installation 

I dont want to compromise the integrity of the piece with grinding, but im currently stuck on that part. Have you had any issues or increased NVH from grinding the piece down?

+JBWHITEGT No they do not raise the car at all

Andres Rios You must have the 2016 GT model like myself as we had major difficulties getting it in and managed to get it in with 2 guys. Even Steeda's subframe brace was also a pain on the passenger side as you couldn't just loosely thread them in and took 2 guys as I had to use a prying bar to position it and the second person threading it in! Steeda should also mention that on Base not PP 2016 GTs you will have a more stiffer ride but they will deny that and give you the same bullshit response and say "We've sold over 2500 units and no one has reported any problems "...I guess I'm just crazy because one of the main reasons I chose the base GT because of the softer suspension compared to the PP, now my car rides like a PP!

+Dennis H I did not notice any changes in NVH with my car, I went with the red bushings for the diff

Bill Tumas Bill on a PP that we all know you have you probably won't notice anything but I can assure you on a base 2016 GT it will change it drastically as from a nice soft ride to more like a PP stiffness. I got the bushings and the subframe brace from Steeda and installation on a 2016 is also much more difficult than a 2015, it does not go on as easy as what they showed on Steeda's video for the 2016!

It's never a bad idea to check them, I removed mine for a new install the other day and they were still tight

+Bill Tumas awesome, thanks man

Doing one side of the subframe at a time will keep the subframe where it was from the factory which is not always straight.

CJ Pony Parts so what you are saying Bill Ford didn’t straighten the subframe on, on this 2017 model also. Question if decide to try to installed one alignment Steeda sleeve with support if it push in easy with lube it would be ok to continue. Also by measuring from side to side with a plum bob on a string it look about a strong 1/16 in different. Thanks!

Seems like vertically only, horizontal would be the IRS braces product

5FaLlEn5 They both do the job, IMHO I think the supports will add a little more strength

Bill what would be better adding these bushings or adding the support frames instead .. thanks

​@@demolaj1I just did the support braces but that by itself doesn't eliminate wheel hop because it seems most of the hop comes from vertical movement which this aims to fix

+ORANGE COYOTE Torque specs are recommended for a reason.

+Dennis H I added those while filming the install, we already shot a video on them so I didn;t mention it

Thanks Bill. Your how to video's are great btw.

+TruBlue16 It made a huge difference. With the Steeda IRS braces and this I have none

+Bill Tumas Awesome thanks!

+Bill Tumas would it be overkill to add the vertical links and diff bushing set with the set up you just mentioned?

​@@Zerogivengaragedid you have to remove the braces to install this?
