If I change wheels or tires do I need to get the alignment redone?

I currently have 19" with winters on my GT4 and it will get aligned on Friday for the track season but I might not have time to put the 20" with cup2 back on prior to that....

Maybe. Depending on your 19" you may not have enough room between the barrel and the toelink in the rear for a track worthy camber setup.

Changing wheels or tires will not effect the existing alignment.

no aligment is based on the rim surfaces, not the tire. but if the tire diameters change ride height, then there can be changes to alignment. but if the tires dont change the diameter, then there should be no alignment changes.
