Hi,
I need your help, the o/s/r coil spring is broken on my 2.5i z4. I wanted to order replacement coil spring. After reading up on the forum suplex ones seems to be way forward. However I am not sure which part number I need. On the brochure there are several part number 6227,6228,29, 30 and 31. How do I know if the car has m sports suspension or not and if it has the "options".
Any help much appreciated thanks.
