yeh im not a fan of slip on spacers though.. less wheel nut thread is dangerous.
i'de put the coilovers in, get some camber arms and get the thing aligned. if your still not happy then perhaps some bolt on spacers... even if you were to put extended lugs on there they are still weaker as the nut is further away still, more distance there is, a higher a chance you have of snapping studs..unless you go bolt ons, I wouldnt consider anything else.
