Out of the Pacific Northwest has grown a sport that is becoming more popular among BMW enthusiasts. Pro 3 racing is gaining popularity throughout Washington State, Oregon, and Idaho. The cars are modified versions of the street-legal BMW E30’s and are modified to spec in order to qualify for competitive races. These are the basic specifications for the BMW E30.

Short List of Specifications:

  • BMW Body Type: 1987-1991 BMW E30 325i, 2-door or 4-door

The idea behind the Pro3 specifications is that no driver gets an unfair advantage. When the class was created, the intentions were to create a PRO3 class that had a restrictive formula for BMW cars that were designed to emphasize driver skill-sets rather than showcasing the design and performance of the driver’s car.
