a thorough shake down of the suspension would be the best bet to make sure all looks well and it tight etc...just take an extra set of pads a set of rotors(f/r) and a couple of tires. those are used the most and you will go through them. Not to mention making sure lugs and everything looks fine before each run..tires/fluids/brakes/calipers working)
good luck on your autoX ventures..
