You get a block of wood, four axles (okay, they're polished nails), and four injection-molded plastic wheels. If you're making a Greatness Cake, that's all you need. You'll pick up at Hand-Eye Supply in Portland, or pay a few bucks extra and we'll mail it to you. It's the official BSA kit, and you'll love it.
NOTE: You must use an official Stumptown 40-supplied kit to race for speed trophies. See the rules for additional info.
