Need experts Advise on suspension
My e93 335i rides rougher than sand paper. This is my second 335 and I'm aware that they ride pretty rough with the run flats but it is just annoying to have such a sweet ride feel like a carriage. So was wondering what is the best suspension I could add to make this thing ride as smooth as possible. Here is my current setup...
Wheels are M359 19' with new non-run flats tires. Car does have a shit load of miles which is why I think my suspension might need upgrading (about 95k highway miles). It is convertible so the bumps are making the car rattle a bit. Any input is greatly appreciated.
