I don't know how you guys feel about it, but for our first race of the season I'm usually happy if the wheels don't fall off!
I had the entire suspension off for tweeks and improvements this winter and no matter how many times you re-check stuff, I'm always a tad nervous about how it's going to hold up untill I run the car for the first time.
The wheels stayed on (but barely, more on that in a bit)
