No prep racing is a type of street racing popularized by the show Street Outlaws. This form of drag racing takes place on surfaces that have not been prepped or treated with traction compounds, which makes it more difficult to control and predict your car’s performance. The cars do not use slicks, instead they rely on their own power to get them down the track as fast as possible. No prep racers must make sure their setup is dialed in just right or suffer from unpredictable handling characteristics during the race. It isn’t uncommon for no-prep racers to struggle when making big changes between rounds, since they don’t have an easy way to test different setups before getting back on track. Despite its difficulty, no-prep racing has become incredibly popular due to its excitement factor and has grown exponentially over the last few years thanks in part to Street Outlaws showcasing some of the best drivers in this style of competition each week.
