Rear engine car ie a porsche, how do they make it handle well?

I ask because i have a model car with two pairs of springs hard and soft, should i put the hard ones at the front or the rear?

My car has a center of gravity near the rear just like a porsche.

Porsche accomplishes the handling capabilities in a number of ways... though ultimately, a car with such a weight distrubition will leave alot to the skill of the driver. The balance is not ideal for many applications, but conversely it allows for it to do somethings that would not be practical to do in other cars.

As to your dilemna with the springs... you say you have a hard set and soft set. Where each should go will depend alot on the just how soft is soft, and hard is hard.

As has been pointed out, the heavier rear will require more spring than the lighter front... and as a generalization, the harder will always be in the back under such circumstances.

However, since this question started off about how to make a rear engined car handle... it will get down to the types of spings and actual rates. While a 911 will have heavier springs to the rear, they may well be proportionally softer than the front in order to help the rear grip more (a harder rear and softer front could well become too "oversteery").

if most of the weight is towards the rear put the harder springs there, the softer ones will bottom out.
porsches are tail swingers by nature all that weight behind the axle acts like a pendulum. also all that unsprung weight behind the axle..

Put your stronger springs in the rear...
