Mustang Skip Barber Challenge - 2025 Season 4

2025 Season 4 - Races every hour at :45 past
The Ford Mustang FR500S has long been a staple of iRacing's road racing efforts. It's a great early step on the ladder, as the 325-horsepower, 4.6-liter V8 is a big step up in power from starter cars and forces drivers to be careful on the gas. In this fixed-setup series, we've taken the pressure of setting the car up properly away—it's just up to you to get the most out of it!
