The drop is moderate and just perfect to my taste - looks way better than my current "high nose - low ***" stance given by Tein H Techs. Awesome photographic skills by the way

And how is the ride? Are these springs softer/harder/feel the same compared to stock ones? What about body roll when cornering hard? For example, my Teins are noticeably SOFTER a more comfy than stock but the car rolls more and loses some edge in handling.

I could say the ride is slightly slightly stiffer, still has the stock feel/comfort, I can't tell if I have less roll but I feel its planted on the ground and my steering has stiffened up a little.

I would concur. The ride is so similar to stock, the change is almost indiscernible. I do believe my wife's car corners harder. I pushed it to the limits on a few curves over the weekend. I attribute this mostly to a lower center of gravity, as the spring rates are so mild. Great spring choice for these cars.

As information, the rear camber was 2.4*L/2.3*R negative after installation. Too much for my taste. Set it up to 1.4* negative with the adjustable camber arms.

Car drives perfect. I drive my F hard, my wife drives this car pretty aggressively at times too. As soon as I pulled it off the alignment rack I drove it on one of my favorite long sweepers.... 95 MPH and the car handled impeccably.

As the original OP Albert states, car rides incredibly. You would be hard pressed to differentiate between a stocker and one lowered with these Swift springs.

On the stock 18's the measurements to the center of the wheel wells with stock springs were 26.5"(F), 26.25" (R). After installation of the Swifts the measurements were 25.75 and 25.5, F/R respectively, for a net drop of .750-3/4". I am assuming they may settle a tad after a few hundred miles.
2200 miles on the springs, front has settled about .125. Rear has not moved. Net drop with these springs on this car is .875-7/8" front, .750-3/4" rear.

The claimed drop is -28/-28 mm according to the manufacturer's website.

How is the ride quality compared to stock after 2200+ miles?

That is correct. I always take very accurate measurements when doing suspension work on any of our vehicles, and my numbers are legit. Not sure why there is a discrepancy.

Very similar to OEM. My wife doesn't really dig the ride on my F, (or some of my other vehicles for that matter), but loves the ride of the Swifts on her car.

Glad the wife enjoys it. Happy wife, happy life!

Still trying to find out if these work on AWD. Swift doesn't respond to emails or return my calls. Absolutely ****-poor customer service. I may just go with RSR.

I have the RSR downs on my AWD and it rides almost like stock. Put them on, you won't be sorry.

When should I get an alignment? Did you guys wait until the springs settled before alignment?

That would be best. Some do an alignment right after, but if you'd like to save some cash you can afford to wait a couple hundred miles or a week. Depending on how much you drive your car.
