Mate, i think you have the wrong idea, have you actually tried this?
And to r33zilla your shocks are probably already stuffed, and if you put 2inch low springs in i can assure you it will be much worse.
If you care about handlng you wont lower the car more than 1inch.
Also jap coilovers are not suited to most peoples uses, and you could most definetly get better ride and handling from shocks and springs you choose yourself locally ie the groupbuy at the moment, or like myself bilsteins and whiteline springs.
