Twitchy/Notchy steering!

Only recently got my Z4 but after using it over the weekend I’ve noticed I seem to be constantly adjusting the steering it has become quite unnerving. It has non run flats Dunlop Sport Maxx which are about 500 miles old and the lollipop bushes were replaced last year. I have looked at the threads regarding this so will start with a 4 wheel alignment as not sure if this has been or should have been done after the bushes were replaced. I will get the other bushes checked but really don’t want to get into steering racks and ecu reprogram. Strangely enough it has seemed worse since the hot weather arrived, not ideal for my trip to Spain next year though. Any help would be really appreciated. Thanks
 
Have a read of this thread. Its a relatively quick and easy fix.

My Zed wanted to kill me when I first got it, that's what it seemed like. It was like someone was pulling the steering wheel. I fitted 18" wheels, that helped, then played with tyre pressures, also helped.
Then, after sending the ECU for repair, I adjusted the concentric ring when refitting the motor, that really helps. It now drives spot on :thumbsup:
