I have a 23.5 GT as well and installed the Eibach lowering springs, Koni rear adjustable shocks. Oh and I also have the Eibach sway bars too.

The Springs really cut the harshness you describe when you transition from one road time to another. I mean like half of it IMHO.

My Eibach springs are supposed to arrive today and I'll get them installed toward the end of the month. My questions is.....since I'm taking the car in, should I also do the Koni rear shocks and set them for 1.5. Don't have a lot of roads with repetitive seams, but in Vancouver WA and especially Portland OR, some bad city roads. Should I spring for another $500 (is my guess) as the shocks look to be on sale for $130 right now.
I'm not doing the sway bars.

Hey Doug, I wouldn’t install the Koni rear shocks. They are meant to lessen the rear repetitive bounce over certain road conditions. They will also give you a more harsh ride which is what you are trying to eliminate. To further reduce harshness I would have the Eibach sway bars installed. The OEM sway bars have vulcanized rubber bushings that don’t allow the bars to move as freely as the Eibach bars with their bushings. Not to mention it’s the single best mod the car needs. It will handle so much better and how it should have to begin with.

Springs = your butt will thank you
Bars = your neck will thank you
Shocks = your rear seat passengers will thank you.
GTPE = your right foot will thank you. :)

I know a few of you like the lowering springs and some like the ones that raise the car. Are there springs that don’t change height but improve the ride (other than those expensive coilovers)?

Actually I don't think the suspension is stiff. I think it's undersprung and wobbles because it's so darn heavy

Sadly not at this time.

A lot of that wobble is the tire sidewalls

Wondering the same. I think the height on the GT is good. Any lower and you're scraping the front lip.

I agree. I prefer the height on the mach-e as is but I went with the Eibach lowering springs for the better ride conditions and unfortunately they don't make a comfort spring at stock height.
I wouldn't say it looks super slammed or anything and so far I've not had any issues coming in or out of angled driveways, etc. There still is slightly space for the front lip to clear curbs, etc

I've been running lowering springs on my GT for over a year and a half. I have yet to scrape the front lip going in and out of driveways, etc. My car has cleared every parking bumper that I have pulled up against and I do not pull up to any curbs that the height looks questionable.

I agree with Brian above and others it would be nice for Eibach to make stock height progressive springs but the lowering ones have been no issue at all for me.

Same for me. I had no desire to lower the car, but the inch or so lowering has so far not caused any problems.

Thanks for the replies to my question about springs and the helpful comments about the lowering springs. I'll go back and reread the thread about the springs that raise the height, but can someone remind me if they provide a similar ride to the lowering springs? I realize there is a bit of a hit on range but curious about the ride.

It gets a bit hard to remember the big picture sometimes given all the detail, and appreciate @azerik's quick summary above, but not sure I understood the part about springs helping one's butt but the shocks (presumably the Konis) helping the rear passengers. Is it that the springs soften the ride a bit and the Konis reduce the rear bounciness?

Correct. The springs alone will help with some of the bounciness. Sadly none of these are the golden ticket.

The lift spring don't really help with the harshness of the ride since they are linear just like the OEM springs. You want progressive springs to cut the harshness and they are only available in the lowering springs. This is the Eibach part number to get if you want them: Part #: E10-35-054-04-22.

The Koni shocks are to lessen the rear bounce and while doing that they will make the ride slightly more harsh so if you don't have the constant chronic bounce over certain road surfaces do not get the Koni shocks. The springs will be what you want and if you can, replace the sway bars with the Eibach's also. It will make the car handle much better, lessen the side to side sway and even slightly lessen the harshness. Sway bar part number: Part #: E40-35-054-01-11.
