Looking for a little edge in the aero department? Aero wheels are the way. These wheel disks cost less than $2 each.
Step 1: Gather Materials
Here's what we used
A sheet of an unknown plastic. It was thin, very flexible and appears not to be very brittle. But more importantly, it was $1.75 for a 2' square sheet. I love surplus.
You will also need a cutting device - we used a jig saw with a fine metal blade.
A stiff backing - we used some scrap foam - this makes cutting easier
