Thanks for the advice James,
Coilovers do sound the best bet, but having just paid for the rims, I don't think the missus would be too pleased if I told her that I was gonna spend a further £1k and therefore she must go on the streets more often
Springs seem the best bet at the moment perhaps. Have to be careful as the car is still under warranty and any given opportunity, the Nissan dealer will 'worm' out of issues by blaming the aftermarket kit, no doubt
Right then......I'm off to buy some Autoglym
