I have a 2020 GT non-PP. I am very happy with the current ride but I am moderately unhappy with the altitude. I am extremely hesitant to pull the trigger on springs for fear they are going to stiffen it up too much. I know this is somewhat subjective. I have read through the spring sticky and would appreciate further guidance. My criteria:
1) Lower 1" or less
2) Maintain as close to stock ride as possible
3) Not concerned with increased handling ( I know this will be a moderate byproduct)
4) Intend on retaining stock shocks
5) Planned on using progressives

I considered the FPP X springs (seems I may need camber plates) but even FPP couldn't give me spring rates on them.
Input appreciated!!!

There's a sticky at the top of the page. Do you have questions concerning any of those options?

Yes. I stated that I read through that thread and listed the Ford x springs as something I was considering. Feedback on those would be helpful or any suggestions that fall in my criteria would be appreciated.

Yeah. Ride comfort comes from lots of suspension travel coupled with well controlled motion from quality dampers.

If you lower without stiffening the spring rates, the ride will get worse (you'll be hitting bumpstops waaay more often, which are the worst part of a bad ride.

If you stiffen the spring rates w/o stiffening the shocks, the ride gets bouncier.

You best bet is to lower the car 0.75 or less and increase the spring rate (which, working together, keeps the car off off the bump stops), and then upgrade the shocks to a monotube shock (Bilstein or Ford Track) to maximize ride quality (versus a Koni or ProAction)

don't bother then. The dampers are what needs replacing, not the springs.
Well the springs would need to be replaced to address ride height, correct?

If you want to close the wheel gap, getting some wheels with an aggressive offset (or spacers with stock wheels) can help there w/o touching the ride height.

Thank you for explaining that. Sounds like I'm better off waiting till Im ready to replace the shocks then.

That is a good suggestion also......although for now I'm pretty content with the wheels.

Springs, sta-bars, shocks and struts . . . if you could pick only one of those three you should make shocks and struts that choice.

I run X springs and Bilsteins...a match made in motoring heaven.

I’d guess this setup is 5-10% stiffer than an OEM PP’s, but don’t let that steer you away. The ride quality is seriously good, the handling is much improved (especially with Steeda bars), and the car is vastly more controlled.

Thank you everyone. I don’t think I took the shock/spring relationship as seriously as I should have. Kinda see this now a bit more like a cam/valve spring setup. I know it’s not the same but yet there are similarities.

What particular bilsteins are you running?
