Interesting investment: All the plates in the Pilot F-16 series have interchangeable components and trucks. They also have the same mounting pattern, so you don't have to redrill holes to change the plate. This makes the upgrading to another plate or to different parts ridiculousluy easy.

The size of the plate is the wheel base in inches. If you're looking for a plate with a 6" axle to axle distance, go for the size 6 plate.
