Thanks for all the interest on the type of racing surface for 1/12th scale. We are happy to have all the international and US drivers attend this IFMAR World event. We expect that some may not be able to make this event and we feel honored to host this race. IFMAR is the organization of the worlds and Kissimmee Full Throttle Raceway is just the host at our facility. We have no control on rules concerning the actual race and if the tires are controlled or open. I am more than sure IFMAR would like to hear from all of its racers.
I am under the impression your referring to the yokomo rubber that Masami used. If that is a concern maybe IFMAR should make a call on that class.
We are working together to make this a great race.
