I've haven't spent too much time online but from what I've played, there hasn't been any lag. It stayed locked at 30fps for the most part. Only when you have a shit ton of people going around one turn would it slow down at all but even then, it's not bad by any means. It's pretty easy to get a race going. If you join a race while it's in progress, you just watch a grid of what's going on until the race is over. I haven't setup a car club yet.
