[Rion]

an autocross next year..
What do i need to do?

[sil3ncer7]

Pay the fee, Pass tech, Have an approved helmet, and wait in line..

or what do you mean "need to do?"

[Rion]

I guess thats all, wasnt sure if there was some secret society I had to join to get track day info.

I believe the helmet rules shift to the next set every 5 years... so I think this comming season you may need to get a snell 2k5 or better.
stlscca.org and solo2.org will get most the information you could ever dream of including the rule book.
