My friend recieved a test prototype set for his Z and I drove it around. Honestly you would probably have to drive it to believe it, but it really is more comfortable than stock, but it corners like your on a set of coilovers.
I didn't realize that so much of the road vibrations is felt through the car, until I drove the 370z with the Swift springs on it. The owner says he loves them but says that Swift might change it up a little bit for the production model.
I am already pretty much sold on them so I will do a write up on them when the production model comes out.
Anyways I have pictures of the car lowered on it. Cell phone pics but should be decent quality.
