Koni FSD's / Yellows and the N54 E93

You 335i E93 owners -- who's running Koni FSD's?

Now who's running aftermarket springs?

No BMW Performance Yellow springs for the E93. Anyone running 'em anyway?

How 'bout you Ground Control drivers: Is there an E93 running Street/School? Yup, I know they're Yellows, 'specially valved.

Today my dealer's parts dept claimed E93 springs are the same as E90 & E92.

How 'bout you BMW techs - True?

Shocks might be diff....sway bars def might be as torsional rigidity's diff.... but how much?

E93 sways diff on M3. Hey.

the springs cant be the same b/c as you know the e93 is 400lbs heavier then a e92 which means e93 spring weights should be alot different....someone correct me if im wrong

You're correct about add'l weight - yet if you spotted my corner weighs, mass shift was surprisingly small, up/down front/rear.

Evidently most of the top's mass is in the hydraulic drive - doesn't change position. Up/down impact on springs/shocks is minimal. But I asked my dealer 'cause I thought as you that springs would be diff due to weight. Still suspect so!

Anyone give us a reference?

Center of Grav was of course lower, top down, yielding noticeably better handling. I feel that!
