I just received my VOI7 packet, with the cool Viper luggage tags (surprised they weren't Dodge/Viper red). Anyway, looking through the packet, much to my surprise, there was NO mention of RT/10s on the track and requirements or lack thereof regarding the need for tops on. They mention helmets, but no mentions of tops. I don't want to assume they are unnecessary and get screwed, nor do I want to lug the hardtop unless it is necessary. Who should I speak with to get an OFFICIAL response on this matter? I'd like to know a name before I simply call VOI7 HQ and get a response from someone that might not have the correct answer.
