Or you can throw in a megan upper control arm! Unless you really hate camber that much. Heard spacers can be dangerous.
Camber arm won't work. I assume your wheels won't fit over your caliper. I have heard of prope doing this but I've seen the caliper rust and it doesn't look nice after its on. People run spacers but its bit or miss. If say get wheels that fit right.
How thick of a spacer might you need to run? You can figure this out by getting a box of washers that will fit over the wheel studs, measure a single washer thickness, and stack washers onto the studs until you reach the needed spacer width to clearance the calipers without issue. If 5mm or less, just run a spacer.
