It is common knowledge that many Japanese tuners of FF cars, such as Spoon Sports, for example, employ higher spring rates in the front than in the rear of the car. This is generally backwards from the American and European tuning philosophy of higher rates in the rear of front wheel drive cars.

I read yesterday that the Japanese reasoning is that by running stiffer rates in the front, which would generally induce understeer, the car is able to have it's ride height lowered further, lowering center of gravity and improving handling.

Is there any reasoning to that? I read this online, so I am not sure of it's accuracy. The only reasoning I can gather for higher rates in front for front drive cars is because of more weight being up front, and thus encouraging balance.
