warning ...wheel spacers
QD MBE:
For these to have failed, there must have been some movement.
I am not suggesting that you didn't have the wheels tight, the movement i refer to, is the alloy flexing with the fluctating loads on the wheel and eventually fatigue cracks set in (much the same if you constanly bend a piece of metal) and it reaches its fatigue life, and fractures.
Plain and simple. I think you make a good point as to the thickness of the spigot being only 2 mm, not a great deal considering the loading. Another concern of mine, is dis-similar metal corrosion setting in, hence not being able to remove them from the wheels.
They may look good, but their fitment does carry risks.

Confirms more or less what I've been advised - Using them definitely carries risks.
The only way around such risks might be to fit new spacers after every trackday or after just a few hundred miles.

There is a small risk - though this is the first failure i've seen/heard about. I think replacing them every couple of hundred miles is a bit of a knee jerk reaction.... not to say bl00dy expensive :laugh:
The H&R one's seem very well engineered - in fact I have a spare set, will take a pic and post what the 'hub' element is like on them for reference against the OP's spacers.

Of course it's expensive to regularly replace them and that's why motorsport is expensive because parts get regularly replaced before they fail.
The risk may indeed be small, but it's definitely a risk, otherwise this thread wouldn't exist.
It's up to the individual what risks they are happy to take.

Here you go....
These were on my car for about 12k miles - no signs of damage or cracking
