BBS CH HELP Please!!!

Hi everyone. Recently purchased an E8 on 19" BBS CH alloys, lovely looking wheels but appear to have a major issue :cry: The idiot who had them fitted originally has fallen into what appears to be a common problem and bought them with the 112 pcd and put wheel nuts without the correct 60degree taper on them :wallbang: Subsequently the nuts have worn horribly! Its been suggested that assuming the wheels and hubs/threads aren't damaged then using 'wobble' nuts should be fine, the correct spigot rings are fitted and they sit fine on the hubs themselves. Its obviously just the pcd thats the problem, sooooo does anyone have any experience of the wobble nuts on these wheels? is it safe? im not going to be tracking it, just dont want any disasters! If this is not a reliable option, i understand its possible to have the pcd altered to 114.3 somehow, has anyone any experience of this and if so who does this, where are they and how much!! Im in Norfolk area and im a noob member, any help you can offer would be much appreciated:smthumbup
