Use this guide to quickly look up the quality of your parts. Most parts are in tables like this, with the names in alphabetic and numeric order, and “1” next to the best part:
3 bad part 1 best part 2 good part ? part with [50 40 30] units of slowness ? part with [80 70 60] units of quickness 4 worst part
Except for the pedal-powered racer, the racers have more or less the same parts, so they start with a one-line summary of parts that can be found under “racer parts”.
