Hi chaps wanting to change my springs on my e85 2004 z4 front spring snapped thought I might tackle this myself on doing first bolt on stay bar or link bar not to sure what correct term the bolt has got a domed head on one side so nothing to grab hold on so couldn't get bolt out as I'm not very confident on doing this job not having right tools is there any one willing to give me a hand and help me change them I live in west Bromwich west midlands would be very grateful to anyone who can help with this problem thanks mac.
