I made this guide to help make teching at races faster and easier. This guide will check for the size of the hard body, the with of the following tires (8.5mm, 11mm, 14mm), as well as the maximum height of 25.5mm for tiers. This will also check for the bumper clearance as well and to make sure the wing is not too tall. This gauge was made for the 2024 West Valley City Grand Prix using the Rocky Mountain 1/28 scale alliance rules. The small gauge will nestle in the big body box for storage. If you have any questions let me know. Happy racing!
