For those of you who track your cars, how often are you getting an alignment?
1) After x number of track days? If so, how many?
2) When you feel a difference in your car's handling?
3) Based on uneven tire wear?
4 Other criteria? If so, do tell

Great topic for discussion in length but my short answer
it will depend how aggressive is your driving , if you are really pushing it , I would first do a proper track set up and check it every 2-3 full days if hard driving on the track
More than alignment I would be worry about checking and tighten every bolt on the sway bar er etc
once I found a loose ring on my sway bar, it would’ve been a disaster if it fall off

All I can say is my 996 GT3 has only been aligned around 4 times with over 100+ DE track days. There are several factors. Is the car for the track only or does it go on the street?
How hard to you drive the car? Do you drive on the curbing, etc. Generally speaking, the alignment holds pretty well unless you are abusing the car. It does not hurt to check but there is no way after a few track days you should even be thinking about an alignment.
Yes, an alignment can make a big difference in how the car handles.

Every time you do an alignment, they check the initial state, so you know if your car went out of alignment since the last time. That can tell you how often you need to check it. FWIW, my GT3/RS cars never went out of alignment over 10 years, even after being launched 5ft in the air or after cracking a wheel on a curb. So I would not worry about it much unless you have a special reason to.
