well today i checked the not broken 7mm spacer against the 2 front disks and theres a tinygap when they are pushed to the disk.barely get a bit of paper between them but that's why the other spacer broke..
my solution is put the 7mm and 9 mm on the one wheel to give 16mm spacer..looks quite well now but need spacers for the rear now..
put the broken spacer on the inside and the 9 mm one on outside of the broken spacer to keep the lip for the wheel..
emergency over I think..
