Mid engined cars are great in the hands of race drivers. But that low polar moment of inertia can bite you.

I agree with RC, a mid-engined car will spin like a top if provoked (like the figure skater spinning faster as he/she moves arms closer to the body - lower polar moment of inertia).

The most forgiving layouts are those transaxle cars (944 et al) that have equal portions of weight hung out from both sides of the car's central vertical axis.

However, if you are on top of it, nothing will have the turn-in or reflexes of a mid-engine layout, other factors being the same ...
