Stage-1 frictions are not limited to performance, but also enhance heavy duty applications by increasing holding capacity, while being able to withstand higher temperatures associated with towing heavy loads. Stage-1 Performance frictions are the best choice for street rods, tuner cars and mild street strip applications.
