The process of building a off road racing rig (or any racing rig) from scratch to driving is a big project no matter what your experience level is. Here are just a few photos to give you a small idea of how big a project like this is. The crew at WCBA Racing has many years experience of building rigs from the ground up for Tuff Trucking Arena Racing. All the work was completed in just nine moths from starting the build to first race.
