Welcome to !
Lots of capable people on here who can help you out. I'm definitely not one of them.
As this is the newbie intro section you might not get much traction in regards to users seeing this and replying. I can move the topic to a new section for you if you'd like?
Ok, so, the seller has replied to me finally. It seems my hub lip is 12mm and their spacers are 10mm. That explains I guess how the lip is ripped off the rest of the spacer.
Of course they're blaming me for this.
