For the past two years, I had an RS4. It was firmer, with less body roll than my 330. But it was MUCH quieter over rough pavement. I could feel the bumps, but it didn't sound like the car was crashing over them. A lot of people blame the larger rims on the rough ride. Well, the RS4 actually had 19 inch rims, one inch larger than the 330.

I now have a 2009 335 with a sport package. Even with stock shocks and RFTs, the ride isn't as loud as my 2006 was. It's nowhere near as quiet as my RS4, but it's passable. And I know I can likely improve it with Koni FSDs and regular tires.

I'm not sure why the ride on my 2006 was so bad. Yes, you can improve it further with FSDs (especially at higher speeds), but don't expect a miracle. Good luck!

Thank you Spagolli94 for the info. I guess it is possible that the 2006 E90 is not as refined since it is the first year model. Based on the information, the KONI FSD may provide some improvement but definte no miracle to make the car ride like a lexus is or audi a4 which is what I am hoping for.
