pressure will DECREASE grip, so having high pressure at the front and low pressure at the rear as you recommended will actually make your car UNDERSTEER more. To answer maverick's question: you didn't specify what you meant when you said you want the car to handle well. Nissan's recommended tire pressures are 33psi front, and 36psi rear. At these pressures, the Z is tuned for mild understeer at steady cornering. If you wish to change that to less understeer, you can increase the rear tire pressure and/or slightly decrease the front, but unless you are racing, I don't think it is really necessary nor desirable for typical street driving. You can also adjust the car's handling balance by changing the anti-roll bars. There is also a write up on how to set up your car for Auto-X, which describes how to set the rear shock valving stiffer than the front (causing more tendency to oversteer) with the stock adjustable TT shocks.
