Which Spring will straight line "feel" like the M3?

Installed new Koni Adjustable on my 335i Stock Springs. Still feels floaty especially at high speeds. I'm sure its the progressive spring rate that the 335i utilizes for comfort. Which spring should I use to "feel" more like an M3 with better road feel. Was thinking the H&R. But then they make several types. Opinions welcome!

have you adjusted the shocks? the konis should not feel floaty at all. I;ve been running koni sports with stock sport springs for 3 years with them adjusted about .75 turn from full stiff and the car is very stable.

Agree with mike - the floatiness won't be addressed by springs. That's all about damping rate. Adjust your shocks.
