BMW Z4 Difference in Rear Suspension Height

[Nothgiel]

I recently changed my springs on my BMW Z4 3.0i because the left side was four centimetres higher than the right. The springs I used were identical Suplex 06231 springs for Cars with M Sport technology. The springs have now settled over a couple of weeks but I still have a height difference of 4 cm with the left side measuring 640mm and the right side 595mm with 18" alloys. the correct ride height should be 588mm +/-10mm so the left side is way out. Have you any ideas of why this might be????

Have you checked the thickness of the rubber pads which the springs sit ? Have you tried sitting the on the wheels with the shock absorber bottom bolts removed and the shockers dis connected?

Tony.

ps. Also is there any difference on the front end?

Hi Tony Thanks for your reply there was no difference in the front suspension it measured 595mm. I will try removing the shock absorbers and see what happens.

Thanks John
