Almost the only cars that can fit 56/58mm motors would have to be 1/5 scale cars. Smaller cars would need a different motor mount to fit something that big although I think the Traxxas XO1 may be able to fit one on its stock mount. Also most 1/5 scale motors are lower kv that would require at least 10 or 12s to make optimal power. Its challenging to fit that much battery in something smaller than 1/5 scale. Not to mention the extra weight could negate most of the extra power of a 56/58mm motor.
