I currently have 3 (1.5hr) stints available for the 12 hour AER race at Charlotte. Reasonable rates and a guaranteed good time!
Car is a well sorted Class 1 Miata (NA) suitable for drivers 6ft or less. Prior W2W is required to race with AER. American Endurance Racing is by far my favorite budget racing series...it's a bring what ya got series where you are classed based on qualifying times, not displacement.
