I wonder if they'll let those that don't have enough subscribers "buy in" somehow? That would kinda suck to go all that way and not be able to compete.
I would say if you have less than 450 subs, I wouldn't go planning to race. IF you have 485 subs, you can pan handle at the gate and say "subscribe, get me in"... LOL If I know this community, you'd be able to race in 10 minutes
