KW Suspensions or is it "KY" suspensions. Don't bend over...stick with OEM for now unless you have to change out.

yep exactly, from the web this seems to be my solution to slam my ride without sacrificing the ride comfort. the damping can be adjusted too like the V2...

Very interesting news, do you know anything about price. Do they lower as much as the normal KW coilovers??

Difference btw KW V2 Vs KW Street Comfort

Here's what i got the reply from KW Germany today.

KW Street Comfort is more comfortable than the KW coilover Variant 2.

BUT the Street Comfort has only a lowering from 15-35 mm on the front and 10-30 mm on the rear axle – KW Variant 2 allow a lowering from 30-60 mm on the front and 20-55 mm on the rear axle… that means shocks and springs are different on both applications…

Having both more comfort and lower ride than OE is not possible without risk of bottoming out (which would be very dangerous in the middle of fast curve).

No, it's entirely possible. As long as you've got progressive, or dual stage dampening. But as the piston of the damper gets toward the end of it's travel the "comfort" part will go away quickly.

Dude, I hear you about the scrapes. these cars have a very low front valence.

I am also pretty interested in the KW Street Comfort kit. Does anyone know what the pricing will be

based on the figures given by KW in the above, the street comfort coilover will drop our ride as with the H&R sport (1.3"F/ 1.2"R).

but i hope these new coilover will drop further to 45mm for E90 application as per the KW website.

1 inch = 25.4 mm

-i have the V2s myself and i can personally tell you that the setting they come on are better than the factory E90 sport suspension!! infact, the german that installed them said i didnt need to adjust the dampning because it rides fantastic already! minimum body roll and it rides great! if you can spend the $$ its better to install them once and get it right the first time, bro!!
My .02
so, your ride in the pic has KW V2 already? how much you've lowered them?

You are right. I just did not think of progressive springs.

For progressive rates to work well it would be good to have enough suspension travel to take advantage of them. Otherwise, as you said, the soft part is used quickly and leaving a limited amount of travel for the stiffer portion to deal with, resulting in less compliance and less traction.

In an optimal world damping rates would need to be matched to the spring rates, in particular rebound damping, and with progressive rate springs this is impossible.

The above mentioned is not too important/relevant for a less enthusiastic driver though.
