Having a wheel fall off is my biggest track day fear - even more so than losing the brakes. Saw an E92 M3 loose the front left wheel coming down the outer loop at WGI last year. He ended up in the wall and upside down. He was not hurt and luckily had track insurance because the car was totalled. Evidently, he had noticed cracks on the set of oem bolts at one wheel and replaced those, but neglected to replace all of the bolts for the remaining wheels. Lesson learned I guess.
Having said that, I am running with a set of Apex studs all around. I have one year on them (15 or so days) and plan to replace them at the end of next year. No visual issues of wear yet but I check them every track day morning as I switch over to my track wheels.
In addition to replacing them periodically and keeping the mating surfaces clean, I avoid loosening/tightening the studs/bolts when they are still hot from a session.
