I plan to autocross my car more often this coming summer. This requires more travelling... a lot more. At times I will be 25-1500 miles from home. I am bringing a trailer so that I can take my tires, spare parts, change of clothes, etc. When I am racing my 2010 R56 base hatch on the autocross course, what is my list of parts I am going to be thankful I brought if I hear a snap.
