the big problem with the lighter weight lipo batteries is that you are reducing the amount of weight on the tires which in turn reduces the size of the contact patch of the tire touching the ground. Suspension settings can not change this, only car weight, downforce (only at high speed) or tire/insert compound changes can change the tire contact patch. Going to an even softer compound tire would not be good if the races were made longer to take advantage of the increase of battery capacity. I feel the best solution would be to leave the existing weight rules in place. Racers could add weight to bring the cars to legal weight for the time being. Car manufacturers could then use the weight savings of lipo to design the car parts stronger and more durable, strong enough to last the longer races that lipo can provide. This would really help bring in new racers with the benefit of longer runtimes and stronger cars.
