Tires rubbing

today I finally got some new tires on my car, and it is the same tires as before but this time i put a camber kit on my car before i bought some new tires. now only the rear tires scrub the the very edge of the tire. the front is actually a little higher i think because it used to be about 6 inches from the ground and now it is about 8 i guess. but is there anyway i could get my rear end up about an inch or so without having to buy new springs? my dad was telling me something about some spacers i could possibly buy for it but i dont know what to look for any help is appreciated greatly
