I carry at least 2 or 3 2x4s, at least 2-3ft long, and a harbor freight aluminum jack
like this. (they go on sale often, or wait till they send out 20% off coupons)

I also leave a electric impact gun in the trunk (mine is from homedepot, its a Ryobi

and a set of impact sockets from HF

test everything out ahead of time, like making sure the sockets will fit in your lug nut bore. for example, panasports pretty much all need thin wall sockets, normal impact sockets wont fit.
if you have a key for your lugnuts or anything, make sure you have a dedicated place to store It, and that it goes back in the same place every time. nothing worse than getting a flat and not having the key with you.
