You know about the Bit Char-G guide rail set. Personally, I think it sucks. You can't even do a lap without hitting the sides even with a 1.0 motor. That is when I found this Penny Racer track (Choro Q's). It's made for the car to go on the track, but it has enough peices to make a track bigger and cooler than the Bit Char-g guide rails. It's black and it actually keeps the car inside the track. You can also race the Choro Q's and Bit Racers on it at the same time you are racing your Bit Char-G. This is because the borders are made of track. The circuit is actually maneuverable with a 1.0-2.2. Try looking for them in Target. It was 7 bucks.
