So unfortunately H&R doesn't warranty their spacers once they have been installed. Incredibly lame, since when else would you really need a warranty on a set of spacers?
Luckily Josh@Stillen was able to give me a great price, and ensure that I'll get the new spacers on Wednesday.
to Stillen!
I can only hope now that this doesn't happen again with the new spacers too.
Now I'll have an extra set of studs if anyone is interested.
