You pick a ride height for high speeds and set your ideal camber and pinion at that height. You set your steering linkage for this height also.
Then for low speeds using the height adjustment to clear items your tires will be slightly positive camber when raised. When lowered for parking the camber will be negative.
The use of a constant velocity U-joint and slip shaft will allow for the pinion angle changes.
Your tires remain at ideal camber a majority of the time at the high speed setting where they will see the most abuse. The amount of time from ideal is justified as it is temporary. Your not going to be driving around with the front raised or rockers lowered all the time.
As far as bolt in and types. That will depend on the model, space, and budget. Expect to do some fabrication even with a "bolt in" kit.
