As an electric on-road racer, I don't see the problem with tire doping. I've worked as a 1/8th nitro mechanic, and I know anyone at the Worlds certainly isn't short on tires. This is the Worlds, bring out your best, and if that includes tire dope, then I say so be it. It's not going to last more than a few laps, so I say screw the extra tech issues and let 'em run the sauce. Easier on IFMAR, and the race management, and fair to all. Just my humble opinion.
And GO TEAM BSR!!! Good to see a local company have a presence at such a prestigious event!!
