I'm noodling around some ideas for the next Challenge.
Here are some thoughts:
1) allowing only real street tires for the autocross portion of the event next year. Drag tires will still be allowed for the drags.
Treadwear ratings of greater than 140. Other than that, no real exclusions.
2) Requiring fire extinguishers to be installed and within reach of the driver. Free for the budget, but you still need to buy one. real 5BC extinguishers are about $50.
What do you guys think? This isn't official--just some thoughts I had on the drive home.
