H&R Spacer... Lip shaved/broke off?!

i think in HR's case they make their spacers with tight tolerances and with the wheel and spacer metals flexing at a different rate it's bound to snap. perhaps unless you're using heavy materials (something stronger than the wheel's metal) you need some level of 'give' and that's achieved with different materials such as the rings Kics use.

again, im no metal expert and im sure there's a better explanation which HR should provide after doing an full analysis on your failed spacer.
