the GT3 is probably one of the best models in the dNaNo line. its not my favorite car as far as looks but performance-wise, its hard to beat once the necessary option parts have been added. if you're having issues with a bouncy back end, pick up a carbon rear suspension plate (or the fiber type from Atomic) and that will resolve your issue. don't give up on it so quickly, with time you'll find the right setup and beat your best lap times
