18inch rims on a 95 coupe

i need some help. i have a 95 civic coupe with a set of 18 inch rims that i wish to put on. i dont have money for a camber kit right now but i do have coilovers. my question is, can i adjust the coilovers to a height that the tires wont wear without the camber kit or do have to get that damn kit no matter what?

off subject..

i would also like to know what ac compressor and power steering pump would i need( i have a si block, 98 gsr head, in a 95 coupe)? thanks
