Been running both since they were prototypes. I basically agree with lil-bump.
The P56 does have more steering, but on many tracks, I can't keep the rear from wanting to come around. On most tracks, I prefer the P-37. There are tracks such as the GLARC track that I run the P-56 as I need more steering and I can still control the rear of the car.
If I was only going to buy only 1 of those bodies, I would use the P37, but I always take both bodies with me.
