I got a Scalextric race set for Christmas and have already extended the original set with some SCX track. I bought adapters and the track works great with both the Scalextric cars and the SCX cars. Today I got the Carrera Enzo that I won off of Ebay. It will hardly run on this track. It was getting high centered (!) and sputtering around the whole track. I located a 'magnet bar' between the rear wheels and removed it. It improved the ground clearance, but made the engine run even worse. The GT40 Scalextric cars have less ground clearance than the Enzo, and they haul ass, but they do have a shorter wheelbase. Does anybody have any ideas? Might I be having a problem because the Enzo is 'Euro' and not designed for the US market? It seems to do better on the Scalextric track than on the SCX track as the Scalextric track is smoother and less pliable. Any suggestions would be appreciated.
