I've considered all of these amazing performance setups. A proper motorsport suspension could be twice those amounts.

This is not something you'd put on a trailer'd racecar. But if you use your car everyday, are sick of scraping over small bumps, run it hard on the track, auto-x, and rally-x; it offers great benefits, with less compromises.

A strong product. Something to consider for any dual purpose performance car. It's already changed my preconceptions of air suspension. The right engineering can do that.

I was informed today, that Amazon's pricing is a bit askew...As was mentioned, ~$3K and change seems to be a more accurate number.

I raise the rear when I put 4 race tires, tools, jack, and 10gal of race gas in the trunk...
I drop it down on the freeway to get better gas mileage....
Raise it up when there's two feet of snow on the road...
You almost have to experience it to believe it. I adj. WAY more than I thought I would.
