What parts to check after track days to avoid mechanical problems

cossie1600

I don't remember exactly how many, but my car has a lot of track days and autocross runs on them. At 31K miles, I figure it is a good time to replace some of the parts to avoid mechanical problems down the road (speaking as a victim of brake line failure in the past). Here are a list of parts I am planning to replace over the winter, could you guys think of anything that I should replace. I plan to place a giant order before xmas, so let me know what I should add.

#1 Four new brake calipers
#2 Four new brake lines (both the short hard lines and rubber lines)
#3 Upper radiator hose
#4 All new wheel studs
