| That sucks man, but I feel your pain...almost. I was trying to get my wheels & sticky tires on before the last race, but these wheels were special & required a mythical set of lugnuts that nobody has ever seen or heard of & on top of that the place that I bought my tires screwed up with my order & everybody else was back ordered. So I ended up running stock...again. Like I said, not as bad as your situation, but similar, youre all pumped about running your stuff & everything screws up a few days before & theres nothing you can do about it.
I finally tracked down a set of these mystery lugnuts today, now I just have to find some tires that arent backordered & ill be set for the next race. Looks like you'll be all set too...good luck man!! | 
oh well.... 
... just wanted to share
