MRRC UPDATE:
This morning I tested all the MRRC cars I have pictured. These are all used cars out of Goose's stuff, some of them were worked over slightly, some were totally stock. All of the cars had the stock wheels. With stock tires the cars had the typically bouncing and gyrating going on. The cars that he had changed the rear tires to urethane were very smooth running. I assume he had trued them. He also had one car he slipped silicones on. It was also very smooth. This tells me some of the urethane shod cars rear tires may not have been trued.
The only other modifications I found in the cars was the addition of just a little bit of weight. The Cheetah ran exceptional smooth and it had just 1/4 oz. or so of lead just behind the guide flag. None of the cars had the body screws loosened for body float.
Power-wise at 12.75 volts on my track the cars were very smooth and easily controlled. Power delivery was very linear and controllable. I'd say not overpowered or explosive at all.
I think these cars would be suitable for the class you guys have in mind. I would recommend keeping the allowable mods to changing the rear tires to urethanes and adding lead weight. I would put a cap on the car's maximum weight to keep this modification from getting out of hand through "creativity". One or two pieces of sticky backed lead, that's it (INSIDE the chassis - on the bottom NOT allowed).
I will bring some cars to Al's for further testing. Here's my thoughts on the power issue; if the cars have too much power at 10 volts on a shorter, tighter track like Al's, there is no reason the voltage can't be turned down to achieve the desired power level for the cars. I've raced with power levels as low as 6 volts.
