ac schnitzer springs

I have a 335d xdrive msport gt. So comfortable and indispensable to carry around our 3 kids in comfort and absolutely love it.
very stable at high speed BUT cornering needs improving as it kind of slides around roundabouts before regaining composure again(which I can live with but if a solution exists i have an open mind.)
I have been wondering if the bouncy springs are to blame. see video

Anyone who has changed springs or who has researched this please feedback.

foolish me. I changed the driving mode to sport and chose this to only apply to chassis and not to drivetrain. Now I have the perfect car which handles beautifully. when i need a bit of urgency i shift the stick to manual and press the accelerator to gets sports drivetrain and once im done put the stick back to auto mode. sooo happy and kicking myself for not figuring this out earlier.

Please keep us updated! I would love to change to some more aggressive handling springs on the F34!

ACS springs now installed on my 335d GT

Car is still super comfortable. NO effect on comfort that I can feel.
car now goes where I point it. That vagueness I had before is gone.
Steering feels more precise as I know where I am going.
Corners and roundabouts and sharp turns where the tyres would float about before at speeds over 30 miles I can handle confidently now.
reduced body roll so paradoxically increased comfort!
strangely car is quieter!
The chatter that used to come presumably from the dampers is now gone!

If the handling was 3-4/10 before I would say it is 7-8/10(10 being how i envisage perfect handling in a non linear path in wet/dry)

My fellow GT owners
Just get it! It turns a comfortable car to a comfortable and safer and dareisay fun car.

Will post pics soon.
