Ugh... the mentality of all these mod guys kill me. Look if there was an interest by many to run modified, you would see many people racing modified. I am a club level driver, that is all. I have no interest in running mod.
I love the idea of a spec esc and motor for a racing series. Why don't the mod guys like that? Because they are sick of racing the same 15 people at every top level event and want new blood.
Well that isn't going to happen. You can break it down all you want the reasons why people don't race mod. The cost of having different wind mod motors and rotors, the huge wear on the car, belts, drive shafts, tires, or having high c rating batteries. It all comes down to the fact that the average driver cannot mentally wheel a modified car around the track.
Majority always wins. Start listening to your average club level driver to grow racing at your track, state, province or country.
