This weight distribution is really important in handling neutrality. A neutral car neither oversteers nor understeers. The only problem is momentum, since the engine is near the drive wheels. If you push it, the rear will swing like a FR car. However, if you know the limits of these cars, they are the fastest around the tracks.
Power is the only defining limit.
The NSX is one of the only high horsepower cars to use this set up. Therefore, a Skyline GTR or Mustang will smoke most of these cars in pure power. These cars are a trick to learn.
