As far as being as fast as the fastest guys with foams that aint happening, just because your running foam. And as far as guys racing foams at the big races I am willing to bet they are putting a new set on every run or every other run also( I saw the amount of foam tires some of the local racers who are going to the Snowbirds are taking and trust me a new set is going on for every run), and as far as the average joe racer not being able to run a new set of tires every run or every other run because of cost thats an excuse it is not going to make a difference to average racers. I ran one set of tires at the Novak race, if I would have put a new set on for the mains would it have made a difference, NO. If you are a good driver you are going to do well on either foam tires or rubber tires. And again if you are going to run foams because they are faster WHY run a four wheel drive car. Just ran a two wheel drive straight axle pan car, tenth scale or twelveth scale.
