FP Performance springs and if you really want, camber plates. You can also open up the strut hole, like Ford suggests, and get some adjustable camber, especially if not tracking the car. Then either have the dealer adjust ride height sensors, or get forscan and diy.

The FP springs are the best out of the box combo.

All in it should be around $1000.
I hadn’t really thought about the ride height sensors being affected.

I did nothing with ride height sensors, been over a year and no adverse impacts that I know of. The instructions from Ford don’t mention having to adjust the sensors after installing the springs. Just be careful and mindful of the sensors and link arms while you are installing the springs.

That info from before is wildly off
Lowering an inch or a little over will mess up camber out of spec. Front can get camber adjustable tophats on the shock, or a camber bolt. Rear needs adjustable control arm. That will bring your -2.5 deg to spec. Im not sure of mach1 having adjustable camber tophats stock, but if it does then your great! Lowering will IMPROVE the drive quality and handling, not worsen it, assuming you can get back to spec with camber. The toe and caster will easily get put back to oem spec no mods needed. Hell, i have my gt with 1 inch lowered and i didnt even do my alignment, mainly because i havent gotten the parts to fix my camber yet, and i can hit some wild turns no problems, im hitting roughly 1g turns or more based off the g meter in the car
You don't need the adjustable rear control arm, the factory upper arm mount at the body side is slotted so it is adjustable, just difficult to get too. That being said, for ease of adjustment and probably more range, the adjustable arm is nice.

Guess 3 shops on my previous cars didnt know the upper could be adjusted

I respectfully disagree. $2-3K, for doing lowering springs properly? Are you nuts?
Math is hard for some.....

Springs + Struts + bump stops kit+ bump steer kit + camber plates (may be optional) + install + alignment.

I don't even have to add this up and can tell you this is $2K +

For 1” drop lowering springs, none of this is necessary…

OP has a Mach 1, so magneride. Shocks, struts, bump stops and springs you listed won’t work on his car. Just saying this for info, don’t want the OP to place an order based on this parts list.

So you’re saying that I can just install the springs, get it aligned, and roll with it?
If you have magneride i belive they make springs for magneride, if u have norm shocks then totally just the springs and align
If you run alot of camber it will still drive fine, arguably better in turns

I always laugh at GTs bouncing and darting on the road because they took lowering shortcuts reusing stock dampers, no bump steer kit for correct geometry, smashing off stock bump stops, and tramlining like crazy.

It explains why may lowered stangs are at the wreckers as they bounce into trees, cars, posts etc...

No better way to butcher a fine M1 than cutting corners.

The mustang sideways crowd killer meme has nothing to do with people running springs as much as it has to do with alot of power and no experience, specifically it know when to let go of the gas…

stock suspension in a gt let alone a mach1 is superb, lowering springs absolutely will not hurt ride quality.

by your standard of handling, im surprised you even want a mustang, if youre looking for handling perfection, mustang isnt the car you look for lol

You would also think if it is THAT necessary to go as far as get a bump steer kit, for springs, that a single company who makes springs would mention the need for anything you say is necessary

Yes, it has MagneRide. I was looking at the ones specified for it. I was just hoping to get a set, install them, get the alignment checked and let her roll. But if I have to do several other things as well just to get rid of wheel gap, it’s just not worth all that to me.
