Does anyone here using the Eibach pro kit + koni setup for P11? How does it perform and how is the ride? About how much does it cost? I know GAB has the adjustable struts for my car but everyone said the ride is too hard. And I don't think Tein sell their struts without springs. Anyone can help me?

TEIN might sell the springs and shocks seperatly. When I got the 'kit' it came in two different boxes and with two different manuals.

Teins does sell their springs and shocks separately.
As for the GAB shocks, I've tried them with my eibach springs before prior to my TEINs now and the GAB shocks are pretty stiff. The turn-in response is good but if you plan to use the GABs for daily driving, even at the softest setting, the GAB will probably crack your back sooner than u think...it's nice on the track however :)
