can claim in race track?

Well since nobody will give a flying f*** to this question, I shall just entertain myself and answer it.

The rear engine layout is easier to maintain and assemble, but that is besides the point.

Ferdinand Porsche put the engine in the back in the 911 because when you accelerate your car's weight transfers to the rear, so with the engine hanging over the rear wheels, it presses more weight thus giving you better traction and better acceleration.

As such when driving a 911 you can get on the accelerator much much earlier when coming out of the bend than you would in a normal car or supercar, and use the weight in the rear to press down on the road and slingshot you out of the corner.
