You guys need to watch some of the YouTube videos of the Dutch and German Pro10 cars.. Insane speeds. Pro10 run foam wheels, and an aero body so they can put some seriously fast laps in.
When ran 10.5 Pro10 on our local track, if the traction was there would could easily beat the 1/10 nitro sedans coming out of the corner, and they would have about the same top speed.
If our track was longer that might have been a different story, but nitro cars just don't have the torque coming out of a tight corner that we normally run.
Cheers,
