I swear by neuspeed sports. had them on two cars and they give a really nice job without camber problems.
but wanting springs that ride as well as stock if not better is not a reasonable request. the springs are shorter and stiffer which obviously make it lower and provide stiffer turning. at the same time though bumps seem stiffer and your car will bounce a little more cause the struts do not move properly.
I could write on and on but you get the idea.
