As far as I know, there haven't been ANY reported failures from other brand spacers (of the 1 piece variety).
So its either incorrect install
Crap bolts
Crap design or a combination of all three that is leading to spacers flying off.

All the bolts off the T1R DSS are made out of steel alloy steel which has been quenched and tempered. The property class identification is 12.9, you can see this on the top of the bolt. The Proof Load Stress is 970MPA, the Tensile Yield Strength min. 1100MPA and the Tensile Ultimate Strength is min. 1220MPA.
The flange nut is made out of SUS stainless steel 12-70 so if you run a search online to check and you will know that we did not cheap out any material. The only reason that I could think of were the bolts weren't bolted down properly or evenly so under vibration it will go loose.

my kit came with something similar in style to these. i think they were 8.8. this could definately be a weak point because I fail to see how a metal cnc part could move if the bolts are installed and spec'd properly.

did you put never seize on them? I did when i first installed mine (i think i used too much), big mistake that cost me a $350 tow home 
got home, figured out what the problem was and loctited them the second time around

So what is the correct bolting down procedure... torque specs?
FYI, The T1R spacer itself is made by Forged AL7075.
