Race Car Design

a.) Maximum Overall Width (outside edge-to-edge of wheels): 3 “
b.) Minimum Width between wheels – 1 7/8”
c.) Wheelbase – must NOT be changed.
d.) Maximum Length - 7"
e.) Maximum Height – Not to exceed 3”
f.) Minimum Track Clearance - Bottom clearance between car and track - 3/8"

NOTE: Even thought the lane strips are typically only 1/4” high. The extra clearance is to allow the car to go from the sloped portion of the tract to the flat portion without dragging.

g.) Front of Car - No part of the car can extend beyond the starting post and the front of the car must be no higher than 1/2” where it contacts the starting post.
h.) Maximum Weight - Not over 5.00 Ounces.
