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

[James May]

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.

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...
