Since this is my daily commute car also for taking kids to school, is there
way to make the car ride quality better?

I have heard that Koni FSD can improve the ride qualtiy without changing
the spring on E90 sports package. How much improvement will I get by
changing just the stock sprorts shocks to Koni FSD? What else should I
change to make the car more comfortable and possibly raise the ground
clearnace by 1-1.5 inch without buying a new car or change the rim size?
Please advise. Tks.

I feel the same way about my 2011 320D. I replaced the original run-flats with 17 x225x 45 Bridgestone ER300's. There is some improvement over the run-flats but I still get the rumble over coarse pavements. I am considering changing to 16 x 225 x 55 tyres. This is the first bmw that I have owned but on other cars I have noticed that the 16 inch wheel with a 55 tyre is quieter than the 17 inch wheel with a 45 tyre. There is quite a bit of money involved in the new tyres and wheels so I would like to think it is the right way to go. Does anybody with E90 and 16 inch wheels feel disappointed with the tyre noise?
