FWD wheels generally have a positive offset, meaning the mounting surface of the wheel (the part that fits up again the brake drum or disc) is offset towards the OUTSIDE edge of the rim which puts more of the rim under the wheelwell. Standard, or RWD, wheels generally have a negative offset. This means the wheel mounting surface is offset towards the center or INSIDE edge of the rim which puts more of the rim outside of the wheelwell. Any competent wheel or tire store should be able to hook you up. You can also check http://www.tirerack.com for help and to see what wheels fit your car.
