Wheel spacers! Get decent ones for safety sake, demontweeks has a load of different ones but now your car is lowered it'll look better when you have some spacers, will handle a little better theoretically and will let the wheels fill the arches better! Maybe even just at the back, find on my car the rear wheels dont seem to fill the arch as well as the fronts but its a subtle thing that makes a difference! Just make measurements before you buy as you down want your tyres to foul anywhere now your low also!
