I really like this class and from my expierence I HAVE seen people over charge their batteries. It does make a difference, I have never done it my self. Not will to hurt myself and others. I like to practice like I race. When you go to big events they have voltage testers to test the battery so good luck getting away with it there. I have only seen it at a club level. You also mentioned cut gears, seen that to. Agian if at a big race and your car is susspected of cheating they can tech your car. There are also slipper eliminator's. Depending on the track, owner and I would even say the locals, some rules may be observed more then others. I wound not recommend over charging your batteries, (while I don't condone cheating) out side of that I say do what ever you can to keep up with LFG's . Just know if you ever plan to run a ROAR sanctioned event you will have to observe all ROAR rules. That's what I mean by practice like I race. Just my $.2!!!
