Well those offsets are going to require quite a bit of camber to make them fit and a very low ride height. Staggered fitment is fine as long as the tire sizes front to rear are within 3% diameter of each other.
I'm running 19x9 front w/+27 and 19x10 rear w/+30. -2* camber all the way around dropped on BC. 255/35 front tire and 265/35 rear tire with rolled flat fenders.
