you might try putting the sandbags in the trunk. that's where I keep mine, closer to the axle of the car tire.
it's a workout to drive these things. you are right aobut the snowmobile concept. left turns are not so tough, but lean your body to the right to help with the right turns.
I know the odometer is KM. is the speedo in MPH? wish you were closer so I could see how the leading link front end does. I'm running standard forks and I can feel the stresses on it in turns.
curious to hear what you think of the 2wd too!
