What should you do to prepare for a PDX and what should you bring?
For your car:
Tire pressure must be increased a min of 5lbs over normal, better is to set at maximum pressure rating for the tire
Everyone should have a bottle of white shoe polish to make numbers if needed and to mark the sides of their tires (you can also use chalk to mark your tires)
Tire pressure gauge
Torque wrench to tighten wheels or a lug wrench
High Temp brake fluid
Make sure you have plenty of brake material on your pads, bringing a spare set is suggested
