i agree on the custom stuff but getting people to travel across the nation to compete is not as easy as i thought. My F1 race is tomorrow and nobody outside of texas is coming. i think there should always be a open class to see what the cars evolve into! i think i have proven that my IRS car is at the very least is equal to but i think is better than the pan style, at least on asphalt. i dont have a carpet track local and we dont run 21.5 here but if a 3.25 gear ratio will work with a 21.5 i will test that soon. what gear ratio do you use?
