There are 2 ways around this problem. The first is to use shorter 1200 springs instead of Sunny ones. they are the same diameter & rating, but the 1200 has shorter springs which will lower the ride height & remove the positive camber. The second is to use Stanza ball joints. These are longer than the Sunny ones, which will increase the track & change the angle the strut sits at, hopefully enough to get rid of the camber. The ball joints would be the cheaper fix so would be the first thing I'd try. Don't try cutting the spring or heating it to compact it. hope this helps with fixing your problem.
