Been racing a bit of F Class in multiplayer lately. Surprisely its a lot more competive than say A class with it being a lot more difficult to tune up a competive car. I must say though its much more of a challenge and you really have to drive the wheels off your car to get a podium place. The down side though is that its definitely not what you'd call a friendly class with quite a lot of abuse flying, complaints happening and then there's also a large selection of rammers, however, if you can find a good lobby with some like minded drivers then its an awesome experience. I was lucky enough to race with some good people last nite.
