the tire hopping issue was not a problem, i had foam lunchbox size tires, so neither was wheelspin, it was the perfect combo fit the gh2. and as far as steering, it was not possible, it was blast down the street, slow down, turn around, and blast back up the street. one time i did steer at speed ( for what reason, i do not know ) and with the 51 merc body, it was pretty slipstream, the car started to lift from teh ground, air got under it, and it went right underneath my car, upsided down, and at top speed no less, so it was pretty buried under there !! i actually had to lift up on my car and get the gh2 out from under there !!!
