Iron Clad, I'm suprised yours keeps up on the highway just fine...does it have stock rear end gearing too? Mine has the stock 4 speed and the 3:90 gears, it'll do 60-65 miles an hour...if there's no wind, and it's flat ground. If there's wind, a hill, or both, I have to floor it and it wont go over 55-60. Everyone does drive really fast here in Alberta though.
