John, there are lots of 'loaner' cars available so you wouldn't have to miss any racing at Ron's. We all share building processes and 'speed secrets' so none of that is really secret anymore. For tires, I have done fairly well with Yellow Dog urethanes and the NSR rubber tires. It is a shame you missed the race at my house. I was hoping you would come and hang out with us. Welcome. You might want to take notes when you talk to the fast drivers. They know all the good tuning secrets.
