If anyone fancies something different for race B, try the Mustang. Not quite as fast as the WRX for outright lap time but still really competitive. Currently sitting on a low 1:33.XXX after a couple of laps, stringing it all together will get me a 1:32.XXX, and in better hands it's definitely capable of more, it can also hit near 150mph before the first corner so good straight-line too.
Crucially it's also fun and not a 4WD understeery snooze fest, definitely worth sacrificing that bit of time to the WRX for something enjoyable.
