Sorry.
Running on dirt tracks, its important to keep dirt away from rotating parts, bearings axles pretty much everything, even dirt lodging i the wheels can throw the wheel balance off. Racing is not about show, so the important things are aimed towards racing, light, strong, aerodynamic, keep dirt out, and grip. Dish wheels do all of this very well, if it ain't broken, no need to fix it. Plus there are many stylish options that will fit, but be useless on the race track.
I'm not a racer, just a new fan
