When racing offline you'll always have the tires at a constant level of grip where as online you may more than likely wear out the fronts trying to run at a fast pace.
If possible I would like to run both classes. I like the idea of a race on saturday, and a race on sunday. Also, I'm in eastern U.S., would you happen to know what time it will be here?
If there are not enough people to justify the division of times, can we assume that the race where both classes will be running simultaneously is on sunday, 10pm GMT?
I'm not fully sure as I don't know which parts of USA are EST, but I think EST is 5 hours behind GMT so it would be 5pm EST. Basically its when I post this message as its 10:15pm here in UK (GMT)
Yes if there is less than 16 (including myself) signed up for this by the weekend both A & B classes will run at the same time in the same race/lobby.
To answer the Aids questions.
TCS & ABS are optional any others are forced off.
Damage will be on but I don't think it does much anyway (since the last time I was online anyway)
Penalties will be on though I'm not sure about the differences between weak & strong.
Also the track listing is in order, Tsukuba first & Nürburgring Nordschleife last (hopefully for a pretty awesome end to the season)
