What should be installed at the same time?

[Bluemustang]

It seems like each incremental addition to the IRS makes it a better car. Makes the IRS function properly performance wise. That's why I intend to do the LCA bearing and possibly differential bushings to finish it off.

As a result of tightening up the IRS, I feel more movements inside the car. More is transmitted through the chassis and into the driver. When you're going 20mph behind an old lady, not so fun. But during those times when you're pushing the car- that confidence behind the wheel makes all the difference.

I agree with [MENTION=21494]wildcatgoal[/MENTION] in that Steeda and BMR are both great companies who make these parts. Talk to them. Be truthful to yourself about what you want and what you don't want, and they will help you. I know personally that Kelly @ BMR loves to talk suspension and he's helped me a ton. Steeda will work with you as well and can do anything you need.

It's amazing that we have such quality products and research about this stuff to
Mod to our hearts content.

Thanks again for all of your detailed answers. Quite honestly, I think I may be getting ahead of myself. I have a tendency to read other people rave about parts and then declare that I need those parts too. I'm not really dissatisfied with the stock suspension, other than wishing it was lower. I think what I am going to do is get the track pack and jacking rails, and see how i like the car with those mods. Then, I can take stock from there and decide where I want to spend my money. That said, I guess my only remaining questions are:
- Is is necessary to replace all the hardware? I found this kit http://www.cjponyparts.com/ford-rac...fastback-ecoboost-gt-2015-2017/p/MFR3FASTENA/
- Should I get camber bolts?
- Any other little odds and ends that I need to consider replacing when I install the track pack?

I would at least get camber bolts. You may or may not need them. When I installed my Ford Racing springs and shocks (same as the track pack), I needed them to get it back in spec for the front. You should be ok for the rear camber.

1. no 2. they're cheap and the lowering is significant, might as well get them and 3. this: http://www.energysuspensionparts.com/universal-sway-bar-lateral-locks.asp since [MENTION=9985]BMR Tech[/MENTION] stated that the kit is missing this part (and the sway bar might move, I believe it's front only) and may I suggest the cb005 and your choice of alignment sleeve...it takes no additional time when you're putting springs and dampers.

...All of the above are NVH free.

:tsk:

If only that were true...
Something as simple as the Steeds's G-TECH brace adds NVH. I wouldn't remove it because the benefits FAR out weigh the SLIGHT increase, but when I added the Steeda Jacking Rails my first drive on a cement road I had to slow down and turn the radio off because I thought I had a flat tire.

The general dismissal of NVH issues is far too frequent...

 

[wildcatgoal]

While I agree, the dismissal if NVH is too frequent... jacking rails? These were the 1st thing I installed on my car and there was absolutely zero NVH. They don't move...

 

[EcoBOSS]

They don't move, but I'm guessing the increase in chassis rigidity is transmitting more suspension/road noise.
