Staggered means the rear wheels are wider than the ones on the front. You're going to create more undsteer in your car. For FWD application the wider wheels should be upfront. This allows increase grip at the front and allow more rotation of the rear since FWD cars have horrible understeer already. RWD cars run a staggered setup to inhibit oversteer. If you are going to run staggered on a FWD car, you are not going to be able to turn well at all, especially if your driving wheels have a smaller contact patch than your rear wheels.
