NEW FOR 2025!

The MPH Mustang Challenge Series has been created to provide racers with the best value in amateur level road racing by combining the thunder and excitement of American style pony cars with the best possible reliability and durability of the racing platform, thereby minimizing total cost of ownership for racers. The MPH Mustang Challenge Series is a Time Trials competition, not a wheel-to-wheel race series.

The Mustang Challenge Series rules are designed to ensure parity and optimum reliability by clearly defining allowed modifications. Success in this Time Trial competition will come via driving skill, consistency and fine tuning of adjustable parameters.

 

Good sportsmanship is valued more than finishing position. This means clean, will-executed passing is to be a trademark of the series. Punting another competitor or leaning on them to gain a position will not be tolerated. Car to car contact including bump drafting can result in an investigation and possible sanctions.

Manipulating the race start, yellow flags or race results in an unsportsmanlike manner is also unacceptable and will result in possible sanctions.

The MPH Mustang Challenge is open to MPH Guardrail Club members and other experienced drivers driving mostly-stock 2005 to 2009 Ford Mustang GT models powered by the 4.6L 3V V8 engine. ALL competitors will run a “spec tire” to further keep costs down and lap time competitions close.

The MPH Mustang Challenge time trail events will be conducted on our regular MPH Guardrail Club Saturdays.
