I am having a similar problem, I am runninng gen 1 s14 coilovers that I slotted to add more camber. But at that much camber my 18x10 +18s hit the springs even with 30mm of spacer. I am running around 9* of camber now and would like more but unless I run wide fenders (and I don't) the wheels are going to keep hitting the spring.
