What Is 2007 Rolex Sports Car Series

Overview

The 2007 Rolex Sports Car Series marked the 11th season of the Grand American Road Racing Association's top-tier sports car racing series. Sponsored by Rolex, the championship featured high-performance prototypes and GT-style machines competing across North America in endurance and sprint formats.

The series emphasized close competition and manufacturer diversity, with teams fielding Daytona Prototypes (DP) and Grand Touring (GT) class cars. It served as a key platform for professional drivers and rising talents aiming for endurance racing stardom.

• 13 races were held during the season, starting with the 24 Hours of Daytona on January 27 and ending at Laguna Seca on October 21.
• Max Angelelli and Ricky Taylor clinched the Daytona Prototype Drivers' Championship after consistent performances throughout the season.
• The Grand American Road Racing Association (Grand-Am) organized and sanctioned the series, maintaining strict technical regulations to ensure parity.
• Daytona Prototypes were the premier class, featuring custom-built chassis from manufacturers like Riley, Dallara, and Crawford.
• The GT class included production-based cars such as the Porsche 911, BMW M3, and Chevrolet Corvette, competing under modified rules for balance.

How It Works

The Rolex Sports Car Series operated under a structured racing format combining endurance and sprint events, with points awarded based on finishing positions and class standings.

• Daytona Prototype (DP): The top class featured closed-cockpit prototypes with 5.0L V8 engines producing around 500 horsepower, designed for aerodynamic efficiency and durability.
• GT Class: This category included modified versions of production sports cars, with 2007 rules allowing aerodynamic kits and engine tuning within strict balance-of-performance limits.
• Points System: Drivers earned points in each race, with winners receiving 35 points and additional points for leading laps and completing the race distance.
• Endurance Events: The 24 Hours of Daytona and 6 Hours of Watkins Glen required multiple drivers per car, testing team strategy and mechanical reliability.
• Homologation: All cars underwent technical inspection to ensure compliance with Grand-Am regulations, including weight, engine output, and safety standards.
• Team Structure: Teams typically fielded two to three drivers per car in endurance races, with mandatory driver changes and pit stop strategies influencing outcomes.
