Slot it question

Ok guys, I recently bought a Slotit Audi R18 Ultra. Under the case it had two small bags, obviously the wrench is self explanatory, but I have no idea what the other parts are for. This is not my first rodeo but I cannot for the life of me figure out what there used for. Nice car but chassis was really warped so in the oven it went and the front tires went to the razor. Motor pod got the normal tuning as well.
