Just read the AH manual 8-ball. It covers all aspects of this hardcore sim.
I found the detailed maps, and performance charts including Max Speed, Optimal Corner Speed, each varient history and diffrences and the like most informative.
Before, I was clueless and frustrated like you trying to access this hardcore sim, but with that manual, Im okeydokey.
Did you know the top speed of a 202? Hahaha! Me either, till I read that comprehensive AH manual. It's rockin man!
