Anywhere between 30 and 80 I'd say. :wink:
I haven't had less then the high 20s for cars show up at any of my recent meets, and this one is open to all gens of supras and I'm pushing it a fair bit. I have almost 30 people confirmed and I'd expect at least another 20 to show on top of that. We're not doing their famous 80kmph mini indy car carts as those are stupid expensive, require a special license and they only allow 4 cars on the track at once. But the ones we're doing are the next notch down and they're plenty fun, awesome track.
Don't worry about your mechanical skills, this is a meet, not a pissing contest. Come down and have some fun and meet some new people, thats what its all about!
