My Ride: 2006 550i Alpine White/Black Leather/AT
Sport Package, Logic 7 Sound
there is nothingggggggg you can do to solve that problem. My 550i sport suspension rides rough with the stock 18s so i can just imagine the 20s. The only way you can get a little ease is finding the perfect tyre pressure. I run 32psi in my rear (275/35/18) and 30psi in the front (245/40/18). If i run more than that the car will feel like s#it.

My Ride: 2006 530i mystic blue
Check tire pressure and your thrust arm bushings. OEM sport suspension has always been known for its rough ride, but you also have 20's which doesn't help and if you've never replaced the bushings that definitely doesn't help either.... car is 6 yrs old and bushings last for 3-4 yrs.
do u have a link or part number to the bushings ur referring to. my car rides like a brick shit house as expected on coilovers and 25 series side walls! ugg but i never replaced bushings either

Hey Intoxicated,
I think this is what you might be looking for. I hope it will give you a lead for more info. Look up the key words in the DIY sub-forum for more info.

As for the tire pressures, I have been running under 40/45 psi ( for about six months now) for rim protection; the ride is not bad but I will consider lowering it a bit for safety concern. Like some of you guys said, I would not want my tires to pop due to the rise of weather temperatures or frictions.
For anyone who are hesistant to change up to 20's, it's not a bad decision. I can't believe I am saying this, but they look much better on our e60's than 18's or lower. Unless my tire pressures are below acceptable levels, I can't complain about the comfort of my ride under sport suspension and active steering system.
Have a great weekend, everyone!

There's no way bushings can affect ride quality in terms of "bumpiness". Worn bushings will make your car loose track a bit, especially on high speeds, and no, they last much longer than 3-4 years, 70-80k miles easy, provided parts are original BMW.
