Usually for drag racing extra positive caster is added over the stock settings, it helps keep the car tracking straight on the strip at high speed. My car isn't overly fast, but I haven't experienced any issues driving it on the street with the extra caster. I'm not an expert on this by any means, but for camber we usually try to watch how the wheels & tires are going to look through their suspension travel, as far as staying somewhat straight up & down. Some cars going down the track under power keep kind of a nose up attitude, others settle down, it just kind of depends on your suspension & shocks. You want to observe your car under power and take that into consideration when doing the alignment so it remains stable even if the front is a little higher than it would be going down the road at cruise. It's a compromise sometimes.
