This is my first post here on E90post. I just picked up a new 335i xdrive with Msport. My first step was to ditch the RFTs and install Michelin Pilot Sport A/S on staggered 18" wheels.

My installer suggested 32psi front and 33psi rear, so I don't know if that is optimum, anybody have any suggestions?

The tires made a huge difference but the car is "floating" and it is driving me nuts.

I have read all of the suspension related threads and I think my options come down to this:

Springs and shocks: Had a good experience with Koni/Eibach on a 2000 Audi A6 that had the same condition, but I don't want to lower the car too much. Bilstein/Eibach also a possibility

Coilovers: Is this overkill? Height adjustability would be nice to control the amount of drop. Any suggestions for the best coilover for the xDrive?

Thanks for any insight you can provide, and please bear with me if this has already been asked and answered.
