Camber, practically speaking, has nothing to do with bump steer. Without rereading what all we've wrote, to get back to the basics it's all about toe change due to geometry of the tie rod length changing through suspension travel.

Yes, that is what they were designed for.

You need at a minimum,
2x 993RS wheel carriers
2x wheel bearings
2x 993RS outer tie rod ends, these are not sold separately by Porsche so you need to buy either 2 whole RS tie rod assemblies or 2 whole GT2 Evo tie rod assemblies. The GT2 parts are preferred for track use as they have mono-ball connections between the parts, the 993RS has rubber but it is a harder rubber than that used in regular 993s

You will also likely need new ABS sensors as these often fall apart when you try to remove them from the old wheel carriers.
